BEST MODE

Hereinafter, various embodiments of the present disclosure may be described with reference to accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the present disclosure. With regard to description of drawings, similar components may be marked by similar reference numerals.

In the present disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., components such as numeric values, functions, operations, or parts) but do not exclude presence of additional features.

In the present disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.

The terms, such as “first”, “second”, and the like used in the present disclosure may be used to refer to various components regardless of the order and/or the priority and to distinguish the relevant components from other components, but do not limit the components. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the present disclosure, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component.

It will be understood that when an component (e.g., a first component) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another component (e.g., a second component), it may be directly coupled with/to or connected to the other component or an intervening component (e.g., a third component) may be present. In contrast, when an component (e.g., a first component) is referred to as being “directly coupled with/to” or “directly connected to” another component (e.g., a second component), it should be understood that there are no intervening component (e.g., a third component).

According to the situation, the expression “configured to” used in the present disclosure may be used as, for example, the expression “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” must not mean only “specifically designed to” in hardware. Instead, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other parts. For example, a “processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which performs corresponding operations by executing one or more software programs which are stored in a memory device.

Terms used in the present disclosure are used to describe specified embodiments and are not intended to limit the scope of the present disclosure. The terms of a singular form may include plural forms unless otherwise specified. All the terms used herein, which include technical or scientific terms, may have the same meaning that is generally understood by a person skilled in the art. It will be further understood that terms, which are defined in a dictionary and commonly used, should also be interpreted as is customary in the relevant related art and not in an idealized or overly formal unless expressly so defined in various embodiments of the present disclosure. In some cases, even if terms are terms which are defined in the present disclosure, they may not be interpreted to exclude embodiments of the present disclosure.

FIG. 1 is a view illustrating a case 100 and the appearance of an electronic device 200 according to an embodiment of the present disclosure.

Referring to FIG. 1, according to an embodiment, the case 100 may include a fastening part 110, a cover 120, and a connecting part 130. According to an embodiment, the case 100 may be combined with the electronic device 200 by the fastening part 110. According to an embodiment, the fastening part 110 may be attachable and detachable to and from at least part of the electronic device 200. For example, the fastening part 110 may be coupled to at least some of the rear surface 22, the left-side surface 23, the right-side surface 24, the upper-side surface 25, and the bottom-side surface 26 of the electronic device 200.

According to an embodiment, the cover 120 may be in an open or closed state according to a movement of the connecting part 130. According to an embodiment, the cover 120 in the closed state may cover the front surface 21 of the electronic device 200 that faces the first direction 11. According to an embodiment, at least a part of components of the cover 120 may include a transparent (or translucent) material. For example, an area of the cover 120 that corresponds to the display 220, which is exposed through the front surface 21 of the electronic device 200 with the cover 120 in a closed state, may be formed of a transparent (or translucent) material. Accordingly, the user may view images (or contents) displayed on the display 220 of the electronic device 200 even while the cover 120 is closed.

According to an embodiment, the connecting part 130 may connect the fastening part 110 and the cover 120. For example, the connecting part 130 may be attached to at least a partial area of the fastening part 110 and at least a partial area of the cover 120 to connect the fastening part 110 and the cover 120. In another example, the connecting part 130 may extend from at least one of the fastening part 110 and the cover 120 to connect the fastening part 110 and the cover 120.

According to an embodiment, the connecting part 130 may connect the fastening part 110 and the cover 120 through one side surface of the fastening part 110. For example, the connecting part 130 may connect the fastening part 110 and the cover 120 through a left-side surface of the fastening part 110. In another example, the connecting part 130 may connect the fastening part 110 and the cover 120 through an upper-side, right-side, or bottom-side surface of the fastening part 110. According to an embodiment, the connecting part 130 may have a hingedly-moved structure. The connecting part 130 may allow the cover 120 to swing open or close.

FIG. 2 is a view illustrating the structure of the case 100 combined with the electronic device 200 according to an embodiment of the present disclosure.

FIG. 2 illustrates, for example, a state in which the cover 120 is open after the case 100 and the electronic device 200 of FIG. 1 are combined together. Referring to FIG. 2, the fastening part 110 may be coupled to at least one surface (e.g., the rear surface and the side surfaces) of the electronic device 200. According to an embodiment, the cover 120 may be in the open state according to a movement of the connecting part 130. According to an embodiment, the cover 120 may include a base plate 121 and a soft material part 122.

According to an embodiment, the base plate 121 may include a material with a relatively higher hardness than that of the soft material part 122. According to an embodiment, to protect the electronic device 200, the base plate 121 may be formed of a material that is excellent in physical properties (e.g., rigidity, wear resistance, corrosion resistance, and impact resistance). For example, the base plate 121 may include at least one of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS).

According to an embodiment, the base plate 121 may be formed of a transparent (or translucent) material. For example, the base plate 121 may transmit light emitted from a display (e.g., the display 220 of FIG. 1) of the electronic device 200. Accordingly, the user may view contents displayed on the display of the electronic device 200 even while the cover 120 is closed.

According to an embodiment, the soft material part 122 may include a material with a relatively lower hardness than that of the base plate 121. According to an embodiment, the soft material part 122 may be formed of a material that can be deformed by an external force and has a restoring force. For example, the soft material part 122 may include at least one of silicone, rubber, thermoplastic elastomer (TPE), and thermoplastic silicone vulcanizate (TPSiV).

According to an embodiment, the soft material part 122 may be formed of a material that has a specified coefficient of friction or more with respect to a first surface (e.g., the first surface 21 of FIG. 1) of the electronic device 200 when making contact with the first surface of the electronic device 200. For example, the soft material part 122 may be formed of a material that has a specified coefficient of friction or more with respect to the cover glass or the housing of the electronic device 200 when the soft material part 122 makes contact with the cover glass or the housing of the electronic device 200, with the cover 120 in a closed state. For example, the soft material part 122 may include at least one of silicone, rubber, thermoplastic elastomer (TPE), and thermoplastic silicone vulcanizate (TPSiV).

According to an embodiment, the soft material part 122 may be disposed in a second direction (e.g., the second direction 12 of FIG. 1) from the base plate 121, with the cover 120 in a closed state (or may be disposed in a first direction (e.g., the first direction 11 of FIG. 1) from the base plate 121, with the cover 120 in an open state), in which the second direction is opposite to the first direction. For example, the soft material part 122 may be disposed to face the first surface (e.g., the first surface 21 of FIG. 1) of the electronic device 200, with the cover 120 in the closed state.

According to an embodiment, the soft material part 122 may have a ring shape or a broken ring shape (or a band shape with opposite ends not being connected together). According to an embodiment, the soft material part 122 may be disposed in an edge area on at least one side of the base plate 121. For example, in the case where the soft material part 122 has a ring shape, the soft material part 122 may be disposed in edge areas on the four sides of the base plate 121. In another example, in the case where the soft material part 122 has a broken ring shape, the soft material part 122 may be disposed in edge areas on the remaining sides of the base plate 121 other than the side connected to the fastening part 110 through the connecting part 130. According to an embodiment, the soft material part 122 may be spaced a specified distance or more inward from the edge of the fastening part 110.

According to an embodiment, the cover 120 may further include a magnetic material 126. According to an embodiment, the magnetic material 126 may be disposed in the second direction (e.g., the second direction 12 of FIG. 1), which is opposite to the first direction (e.g., the first direction 11 of FIG. 1), from the base plate 121 with the cover 120 in a closed state. For example, the magnetic material 126 may be disposed to face the first surface (e.g., the first surface 21 of FIG. 1) of the electronic device 200, with the cover 120 in the closed state.

According to an embodiment, the magnetic material 126 may generate a magnetic field. A first Hall sensor disposed on the first surface of the electronic device 200 may detect the intensity of the magnetic field generated by the magnetic material 126. The intensity of the magnetic field detected by the first Hall sensor may vary according to a movement of the cover 120, and the electronic device 200 may detect whether the cover 120 is open or closed, based on the intensity of the magnetic field. According to an embodiment, the soft material part 122 may be disposed so as not to overlap the magnetic material 126.

FIG. 3 is a sectional view illustrating the case 100 combined with the electronic device 200 according to an embodiment of the present disclosure.

The sectional view illustrated in FIG. 3 may correspond to an example of a section obtained by cutting the case 100 illustrated in FIG. 2, which is combined with the electronic device 200, along a line 30 across the case 100. Referring to an enlarged image 35 of a partial area 31 of the cover 120 in the sectional view of FIG. 3, the cover 120 may include the base plate 121, the soft material part 122, an intermediate film 123, an adhesive film 124, and a surface film 125. According to an embodiment, at least one of the base plate 121, the soft material part 122, the intermediate film 123, the adhesive film 124, and the surface film 125 may include a transparent material.

According to an embodiment, the base plate 121 may include a fixing groove 127. According to an embodiment, the soft material part 122 may be inserted into the fixing groove 127 and combined with the base plate 121. According to an embodiment, the fixing groove 127 may have a ring shape or a broken ring shape (or a band shape with opposite ends not being connected together). According to an embodiment, the fixing groove 127 may be formed along an edge on at least one side of the base plate 121. For example, in the case where the fixing groove 127 has a ring shape, the fixing groove 127 may be formed along edges on the four sides of the base plate 121. In another example, in the case where the fixing groove 127 has a broken ring shape, the fixing groove 127 may be formed along edges on the remaining sides of the base plate 121 other than the side connected to the fastening part 110 through the connecting part 130.

According to an embodiment, the intermediate film 123 may be disposed between the base plate 121 and the soft material part 122. For example, the intermediate film 123 may be disposed in a first direction (e.g., the first direction 11 of FIG. 1) from the soft material part 122, with the cover 120 in a closed state (or may be disposed in a second direction (e.g., the second direction 12 of FIG. 1) from the soft material part 122, with the cover 120 in an open state).

According to an embodiment, the intermediate film 123 may be used as a base material for forming the soft material part 122 in the manufacturing process. For example, the soft material part 122 may be formed on the intermediate film 123 in the manufacturing process. When the soft material part 122 is attached to the base plate 121 using the adhesive film 124, the adhesive force may be weak due to an adhesive property difference between the base plate 121 and the soft material part 122 in the case where the intermediate film 123 is not present between the base plate 121 and the soft material part 122. According to an embodiment, the intermediate film 123 may be formed of a material with the same adhesive property as, or an adhesive property similar to, that of the base plate 121 to ensure the adhesive force of the adhesive film 124 between the base plate 121 and the soft material part 122. For example, the intermediate film 123 may include at least one of polycarbonate (PC), acrylonitrile butadiene styrene (ABS), and polyethylene terephthalate (PET).

According to an embodiment, the adhesive film 124 may be disposed between the base plate 121 and the intermediate film 123 to bond the base plate 121 and the intermediate film 123. That is, the soft material part 122 may be attached to the base plate 121 through the intermediate film 123 and the adhesive film 124.

According to an embodiment, the soft material part 122 may be directly attached to the base plate 121 without the intermediate film 123 and the adhesive film 124. For example, the soft material part 122 may be formed on the base plate 121 by double injection molding and may be attached to the base plate 121 without the intermediate film 123 and the adhesive film 124.

According to an embodiment, the soft material part 122 may have a width w ranging from 0.4 mm to 10 mm According to an embodiment, the width w of the soft material part 122 may be determined based on the coefficient of friction between the soft material part 122 and a first surface (e.g., the first surface 21 of FIG. 1) of the electronic device 200 when the soft material part 122 makes contact with the first surface of the electronic device 200. For example, the width w of the soft material part 122 may be set to be narrower with an increase in the coefficient of friction between the soft material part 122 and the first surface and may be set to be wider with a decrease in the coefficient of friction between the soft material part 122 and the first surface.

According to an embodiment, the surface film 125 may be disposed in the first direction (e.g., the first direction 11 of FIG. 1) from the base plate 121, with the cover 120 in a closed state (or may be disposed in the second direction (e.g., the second direction 12 of FIG. 1) from the base plate 121, with the cover 120 in an open state).

According to an embodiment, the surface film 125 may have a graphic pattern formed in at least a partial area thereof. According to an embodiment, the surface film 125 may have a specified color. The overall color of the cover 120 may be determined by the surface film 125.

According to an embodiment, to protect the cover 120 from the outside, the surface film 125 may be formed of a material that is excellent in physical properties (e.g., wear resistance, corrosion resistance, and impact resistance). For example, the surface film 125 may include polyethylene terephthalate (PET) to make the surface of the cover 120 hard. In the case where the surface film 125 includes PET, the surface film 125 may have, for example, a hardness of 1H or more. In another example, the surface film 125 may include at least one of polyethylene (PE) and urethane to make the surface of the cover 120 soft. In the case where the surface film 125 includes at least one of PE and urethane, the surface film 125 may have, for example, a hardness of 6B or less.

FIG. 4 is a view illustrating the structure of the case 100 combined with the electronic device 200 according to an embodiment of the present disclosure.

FIG. 4 illustrates, for example, a state in which the cover 120 is closed after the case 100 and the electronic device 200 of FIG. 1 are combined together. Referring to FIG. 4, the fastening part 110 may be coupled to at least one surface (e.g., the rear surface and the side surfaces) of the electronic device 200. According to an embodiment, the cover 120 may be in the closed state according to a movement of the connecting part 130.

FIG. 5 is a sectional view illustrating the case 100 combined with the electronic device 200 according to an embodiment of the present disclosure.

The sectional view illustrated in FIG. 5 may correspond to an example of a section obtained by cutting the case 100 illustrated in FIG. 4, which is combined with the electronic device 200, along a line 40 across the case 100. Referring to an enlarged image 45 of a partial area 41 in the sectional view of FIG. 5, the soft material part 122 included in the cover 120 may make contact with the electronic device 200, with the cover 120 in the closed state. For example, the soft material part 122 may make contact with a first surface (e.g., the cover glass or the housing) of the electronic device 200.

According to an embodiment, the soft material part 122 and the first surface of the electronic device 200 may have a specified coefficient of friction or more therebetween. The soft material part 122 may make contact with the first surface of the electronic device 200 to prevent a movement of the cover 120. The movement of the cover 120 may be more effectively prevented by increasing the coefficient of friction or the contact area between the soft material part 122 and the first surface of the electronic device 200. Even though foreign matter enters between the cover 120 and the electronic device 200, scratches due to the foreign matter may be suppressed by restricting the movement of the cover 120 by the soft material part 122.

Therefore, the following descriptions of the soft material parts 622-1, 622-2, 622-3, and 622-4 will be focused on the difference from the soft material part 122.

According to an embodiment, the soft material parts 622-1, 622-2, 622-3, and 622-4 may be disposed in a second direction (e.g., the second direction 12 of FIG. 1) from the base plate 621, with the cover 620 in a closed state (or may be disposed in a first direction (e.g., the first direction 11 of FIG. 1) from the base plate 621, with the cover 120 in an open state), in which the second direction is opposite to the first direction. For example, the soft material parts 622-1, 622-2, 622-3, and 622-4 may be disposed to face a first surface (e.g., the first surface 21 of FIG. 1) of an electronic device (e.g., the electronic device 200 of FIG. 1), with the cover 120 in the closed state.

According to an embodiment, the soft material parts 622-1, 622-2, 622-3, and 622-4 may be disposed on at least one corner of the base plate 621. For example, the four soft material parts 622-1, 622-2, 622-3, and 622-4 may be disposed on the four corners of the base plate 621, respectively. In another example, the two soft material parts 622-2 and 622-3 may be disposed on the upper left corner and the lower left corner of the base plate 621, respectively.
