Definitions
- the utility model relates to the design of electronic devices with a flexible display and can be used as a case for a mobile phone, tablet computer, or e-book.
- a foldable electronic device housing comprising a first housing part that is integrated with a first flexible display section, a second housing portion that is integrated with a second flexible display section, and a pivot link structure that connects the first and second housing portions of a foldable electronic device, with the pivot links configured to collapse relative to each other so that they extend radially, as viewed in cross section, from the center to form a bend radius of the flexible display and maintain the flexible display in the closed position of the collapsible electronic device, with the pivot link structure further configured to support the flexible display is in the open position of the foldable electronic device; and the flexible display is configured to wrap around the pivot links when the swivel links fold to form a bend radius as the first and second body parts of the foldable electronic device are closed [RU2596469].
- pivoting links provides a smooth bending of the display, but this device is rather difficult to manufacture and unreliable to use.
- the display when folded, is on the outside of the case, which can damage it.
- Another disadvantage is the increased thickness of the case.
- a folding body of an electronic device is selected, containing two parts connected by cylindrical hinges, on which a flexible display is fixed, each part of the body has an outer wall and four side walls rigidly connected to it [published application US20190208656].
- the technical result of the utility model is to increase the reliability and ease of use of the claimed design, due to the simultaneous provision of smooth bending of the display and tight closing of the two parts of the case in its folded state.
- the subject of the utility model is a folding housing of an electronic device containing two parts connected by cylindrical hinges on which a flexible display is fixed, each part of the housing has an outer wall and four side walls rigidly connected to it, characterized in that a damping elastic substrate is placed under the bending region of the display, which is fixed with its edges parallel to the axis of rotation of the cylindrical hinges on both parts of the housing and is configured to loop around the fold area of the flexible display in the folded state of the housing.
- FIG. 1 is a side view in an unfolded state
- FIG. 2 is a frontal section in a semi-folded state
- FIG. 3 is a frontal section in a folded state.
- Cylindrical hinges 1 connect two housing parts 2 and 3, on which a flexible display 4 is fixed.
- Each of parts 2 and 3 has an outer wall 5 and four side walls rigidly connected to it.
- Three side walls 6 of each part 2 and 3 have the same height, and the height of their fourth side walls 7, connected by hinges 1, is less than the walls 6.
- Under the fold region of the display 4 (the central part of the display 4, located near the axis of rotation of the hinges 1) is located damping substrate 8.
- the edges of the substrate 8, parallel to the axis of rotation of the hinges 1, are fixed on both parts 2 and 3 of the housing, for example, by means of fastening strips 9.
- the substrate 8 is made of a sheet of elastic flexible material, such as a polymer, with the possibility of looping around the fold area of the display in the folded state of the case.
- In internal areas 10 of parts 2 and 3 can accommodate the hardware of the electronic device.
- FIG. 1 In the unfolded state (Fig. 1), two parts of the body 2 and 3, connected by hinges 1, are adjacent to each other by side walls 7, and the substrate 8 is stretched between the strips 9 and adjoins the display 4 in its central region (the area of its fold).
- the substrate 8 is bent together with the display 4 (Fig. 2).
- the two body parts 2 and 3, on which the display 4 is fixed are tightly closed with each other.
- the substrate 8 encloses the bending region of the display 4, forming a loop 11, and thereby prevents the parts of the foldable display from closing in this region and ensures its smooth bending.
- the flexible display 4 folds without a gap,
- the hardware of the electronic device is placed in the regions 10 of the housing parts 2 and 3 so that the regions of the regions 10 near the walls 7 of the housing remain free to form the hinge 11.
- the placement under the bending area of the display 4 of the damping elastic substrate 8, fixed with its edges parallel to the axis of rotation of the cylindrical hinges 1, on both parts 2 and 3 of the housing with the possibility of looping around the bending area of the display 4 (i.e., forming a loop in this area 11) in the folded state of the case allows you to simultaneously ensure the smoothness of bending of the display 4 and the tightness of the closure of the two parts 2, 3 of the case in its folded state and, thereby, increase the reliability and operational convenience of the folding case of the electronic device.
