However, the height and width of the front cover 102 may be different from the height and width of the back cover 104 (for example, a little bit different).

Figure 3 shows a top view of the protective housing 100 when in the open position. Figure 3 shows the inner side 108 of the front cover and the outer side 110 of the front cover. This figure also shows the inner side 112 of the back cover and the outer side 114 of the back cover.

Figure 4 shows a bottom view of the protective housing 100 when in the open position. Figure 5 shows a side view of the protective housing 100 when in the closed position.

Referring now to FIG. 6, the back cover 104 is a molded plastic shell with buckles 622 on the upper and lower edges of the back cover 104 to hold the electronic reading device 624 in place. That is, the back cover 104 and the buckle 622 are in the form of a disc, and the electronic reading device 624 is inserted into the disc. The buckle 622 can be made of plastic, carbon fiber, metal, or any other material. In the illustrated embodiment, the back cover 104 is an injection molded plastic shell.

The folding hinge 106 is a soft spine without a base material. The front cover 102 is divided into a plurality of parts by a plurality of folds (such as thermal creases) and folds/creases 618. In the illustrated embodiment, FIG. 6 shows that the front cover 102 is divided into five separate parts, which are defined/separated by three creases and one fold 618. 6 and/or 9 show that the front cover 102 is composed of a first reinforcement portion 602, a second reinforcement portion 604, a third reinforcement portion 606, a fourth reinforcement portion 608, and a fifth reinforcement portion 610. In the illustrated embodiment, the reinforcement portions 602, 604, 606, 608, and 610 are injection molded polycarbonate materials. Figure 6 shows the first crease 612, the second crease 614, the third crease 616, and the fourth crease/crease 618. The first reinforcement portion 602 is in the shape of a triangle, and is bounded by the first crease 612, the second crease 614, and the folding hinge 106. The second reinforcement portion 604 has a triangular shape and is bounded by the first crease 612 and the third crease 616. The second reinforcement portion 604 is smaller than the first reinforcement portion 602 in area. The third reinforcement portion 606 has the same shape and size as the second reinforcement portion 604, but is a mirror image of the second reinforcement portion 604. The third reinforcement portion 606 borders the second crease 614 and the third crease 616. The fourth reinforcement portion 608 and the fifth reinforcement portion 610 form a flap at one end of the front cover 102 opposite to the folding hinge 106. The fourth reinforcement portion 608 and the fifth reinforcement portion 610 are the same size and mirror images of each other. The fourth reinforcement portion 608 and the fifth reinforcement portion 610 are rectangular in shape, but one corner is rounded. The fourth reinforcement portion 608 and the fifth reinforcement portion 610 are separated by a wrinkle 618, which will be described in detail later. The first fold 612, the second fold 614, the third fold 616, and the fold 618 allow the front cover 102 to be folded into a stand that supports and holds the electronic reading device 624 in one of several orientations. See figure 12-14.

The electronic reading device 624 has one or more magnets 626 embedded therein, which interact with one or more closing magnets 620 embedded in the front cover 104 or are attached to one or more closing magnets 620 in the front cover 104. In the illustrated embodiment, there are two magnets 626 and two closing magnets 620. It can be seen from FIG. 10 that when the front cover 102 is closed, one or more closing magnets 620 in the front cover 102 are directly aligned with one or more magnets 626 embedded in the electronic reading device 624. It keeps the front cover 102 closed. In Figure 10, the third crease 616 enables the front cover 102 to completely close the top of the electronic reading device 624, which has an upward curve on the handheld side. It can be seen from FIG. 6 that a closing magnet 620 is located in the fourth reinforcement portion 608 and a closing magnet 620 is located in the fifth reinforcement portion 610. Each closing magnet 620 is equidistant from the fold 618. In an exemplary embodiment, each closed magnet 620 is rectangular, and the long axis of the magnet 620 is parallel to the long axis of the fourth reinforcing portion 608 and the long axis of the fifth reinforcing portion 610. The device magnet 626 may be located in the extended housing portion of the electronic reading device 624, which is used to hold the device with the user's hand.

It can be seen from FIG. 6 that the front cover 102 has a device button recess 628, which accommodates a protruding button 1102 (for example, a page turning button) on the front surface of the electronic reading device 624. In the illustrated embodiment, there are two device button recesses 628, one device button recess 628 is located in the fourth reinforcement portion 608, and the other device button recess 628 is located in the fifth reinforcement portion 610. In the illustrated embodiment, the device button recess 628 is located near the fold 618, and the longitudinal axis of each device button recess 628 is parallel to the third crease 616. The device button recess 628 is not visible from the outer side 110 of the front cover.

The front cover 102 may be covered by a soft material. In the illustrated embodiment, the inner side 108 of the front cover is covered with ultra-fine fiber material. The outer side 110 of the front cover is covered by polyurethane (PU) synthetic leather. In Figure 7, the front cover 102 has an edge 702, which is wrapped by, for example, PU synthetic leather. In the illustrated embodiment, the PU synthetic leather edge 702 of the front cover 110 is covered by an ultrafine fiber lining. In the illustrated embodiment, the edge 704 of the back cover is made of plastic and is not covered by a soft material. It can be seen from FIG. 7 that the weight of the back cover 104 is reduced by including a plurality of grooves (ie, removed parts) on the surface of the back cover 104 (which will contact the electronic device 624). For example, the plurality of grooves may be a honeycomb structure, which allows the removal of material while providing structural strength.

It can be seen from Figure 8 that the outer side 114 of the back cover is covered by, for example, PU synthetic leather. The PU synthetic leather is laminated to the plastic shell (inserted into the plastic shell). In the illustrated embodiment, the inner side 112 of the back cover is only plastic. In the illustrated embodiment, the inner side 112 of the back cover is plastic with one or more layers of paint in it.

FIG. 9 shows the arrangement of various magnets and discs in the protective housing 100. Figure 9 shows the closed magnet 620 previously described in Figure 6. In addition to the closing magnet 620, the front cover 102 has a plurality of built-in stand magnets 902. In the illustrated embodiment, there are three stand magnets 902. However, it may have two, four, five, or any number of stand magnets 902. The back cover 104 has a plurality of corresponding stand trays 904 embedded in the back cover 104. In the illustrated embodiment, the stand tray 904 is made of metal (such as steel). In the illustrated embodiment, there are three stand trays 904. However, there may be two, four, five, or any number of stand trays 904. When the front cover 102 is folded into a stand, the stand plate 904 interacts with the stand magnet 902 embedded in the front cover 102 or the stand plate 904 is attached to the stand magnet 902 embedded in the front cover 102.

It can be seen from FIGS. 9 and 11A that the back cover 104 has a back cover plate 906 embedded in a molded plastic case. In the illustrated embodiment, the back cover plate 906 is made of metal (such as steel). When the front cover 102 is folded behind the back cover 104 for reading, as shown in Figures 11A and 11B, the back cover plate 906 interacts with the closing magnet 620 embedded in the front cover 102 or the back cover plate 906 is attached to the embedded The closing magnet 620 in the front cover 102.

It can be seen from FIG. 9 that the front cover 104 also has an embedded Hall sensor magnet 908. When the front cover 104 is closed and close to the display screen, the Hall sensor magnet 908 interacts with the Hall sensor in the electronic reading device 624, causing the electronic reading device 624 to enter a sleep mode. Similarly, when the front cover 104 is opened, the electronic reading device 624 wakes up. The Hall sensor magnet 908 has a magnet shield 910, so that when the front cover 104 is folded behind the back cover 104 for reading, the electronic reading device 624 will not enter the sleep mode.

Figures 12, 13, and 14 show that the front cover 102 is folded into a shelf. In FIG. 12, due to the interaction between the plurality of stand magnets 902 embedded in the front cover and the plurality of stand disks 904 embedded in the back cover 104, the first reinforcement 602 is attached to the back cover 102. In this position, each of the plurality of stand magnets 902 is aligned with the corresponding stand plate 904. The second reinforcement portion 604 is folded back along the first crease 612, and the third reinforcement portion 606 is folded back along the second crease 614. The edge of the second reinforcement portion 604 contacting the third crease 616 and the edge of the third reinforcement portion 606 contacting the third crease 616 are in contact with each other and are kept stable with each other by closing the magnet 620. Specifically, the closing magnet 620 in the fourth reinforcement portion 608 and the closing magnet 620 in the fifth reinforcement portion 610 are attached to each other, so that the fourth reinforcement portion 608 is folded on the fifth reinforcement portion 610 due to the wrinkles 618. Once the front cover 102 is in the folded configuration just described, the protective housing 100 containing the electronic reading device 624 can be placed in a vertical standing orientation (as shown in Figures 15A and 15B) and a horizontal standing orientation (as shown in Figures 15A and 15B). 15C and 15D shown). Figures 13 and 14 show the configuration of the folded front cover 102 when the stand is in the vertical orientation shown in Figure 15B. When the folding hinge 106 is placed on a flat surface and the folding front cover 102 is in the standing configuration shown in Figure 12, the stand will be in the horizontal orientation shown in Figure 15C.

There is a correct direction to fold the fourth reinforcement part 608 and the fifth reinforcement part 610 around the fold 618. The correct folding direction is shown in Figure 16, and the incorrect folding direction is shown in Figure 17. In order to prevent the user from folding the flaps in an incorrect direction and failing to set the stand, the wrinkles 618 can be completely folded toward the inner side 108 of the front cover (that is, the side of the front cover with ultra-fine fibers), but cannot be completely folded. The ground is folded toward the outer side 110 of the front cover (that is, the side where the front cover has PU synthetic leather). It can be seen from FIG. 18 that the inner side 108 of the front cover has an inner gap 1802 of the front cover, which is very narrow and located between the fourth reinforcement portion 608 and the fifth reinforcement portion 610. The narrow inner gap 1802 of the front cover allows the fourth reinforcement portion 608 and the fifth reinforcement portion 610 to be correctly and completely folded. See figures 20A and 20B. It can be seen from Figure 19 that due to the angled edges (chamfers) of the fourth reinforcement portion 608 and the fifth reinforcement portion 610, the outer side of the front cover 110 has a wider outer side of the front cover than the inner gap 1802 of the front cover Gap 1902. In the illustrated embodiment, the angled edge may be 45 degrees with respect to the vertical. However, the angled edge can be at any angle with respect to the vertical (for example, between 30 and 60 degrees). The angled edges of the fourth reinforcement portion 608 and the fifth reinforcement portion 610 avoid folding of these two reinforcement portions, as shown in FIG. 20C.
