Description

Protective film attachment device for electronic devices

[0001] One embodiment disclosed in this document relates to a device for attaching a film to protect a display window of an electronic device.

[0002] Recently, electronic devices such as smart devices and mobile devices include displays and have a structure that protects the displays by applying a cover window to the front of the display.

[0003] As electronic devices are used, there is a risk of damage or breakage of the cover window due to physical factors, such as impact or dropping. Therefore, users may attach a display protection film to the front of the cover window.

[0004] Meanwhile, in the process of attaching a display protective film, the protective film may be attached without being aligned with the display, failing to protect a portion of the window cover. In addition, foreign substances (e.g., moisture, dust, or air) present between the protective film and the display may cause bubbles to form after the protective film is attached, resulting in user inconvenience.

[0005] In particular, foldable models, which have recently seen a surge in usage, have crease areas due to the structural characteristics of their displays. When users use a display protection film attachment device, air bubbles can easily form in these crease areas. To prevent air bubbles, the protective film must be attached to the electronic device at a consistent angle. This requires mitigating the tension applied when attaching the protective film.

[0006] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0007] An attachment device according to one embodiment of the present disclosure can provide a device for attaching a protective film to facilitate alignment with a display of an electronic device.

[0008] An attachment device according to one embodiment of the present disclosure can provide a device that can maintain a constant tension applied when attaching a protective film over a display of an electronic device.

[0009] An attachment device according to one embodiment of the present disclosure may include a first frame positionable on one side of an electronic device, a second frame positionable on the other side of the electronic device, and a bendable member positioned in a height direction of the first frame and having elasticity so as to be bendable by an external force applied when attaching the protective film. The bendable member may include at least one slit arranged in the height direction, and the bendable member may be formed to be bent from the one side of the electronic device to the other side by the external force.

[0010] An attachment device according to one embodiment of the present disclosure may include a first frame positionable on one side of an electronic device, a second frame positionable on the other side of the electronic device, and a bendable member positioned in the height direction of the first frame and having elasticity so as to be bendable by an external force applied when attaching the protective film. One side of the protective film may be fixed to a head portion positioned on an upper side of the bendable member, and the other side of the protective film may be fixed to a protrusion included in the second frame. When a vertical external force is applied from the other side of the protective film toward one side, the bendable member may be formed to bend from the one side of the electronic device toward the other side.

[0011] An attachment device according to one embodiment of the present disclosure can maintain a constant tension applied when attaching a protective film over a display of an electronic device.

[0012] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0025] Electronic devices according to the embodiments disclosed herein may take various forms. Electronic devices may include, for example, portable communication devices (e.g., smartphones) or portable multimedia devices (e.g., tablets). Electronic devices according to the embodiments disclosed herein are not limited to the aforementioned devices and may include various forms of user terminals, including displays.

[0026] The embodiments of this document and the terminology used herein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, phrases such as "A or B," "at least one of A and B," "at least one of A or B," "A, B, or C," "at least one of A, B, and C," and "at least one of A, B, or C" can each include any one of the items listed together in the corresponding phrase, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used simply to distinguish the corresponding component from other corresponding components, and do not limit the corresponding components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as being "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0027] According to some embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the multiple entities may be separated and placed in other components.

[0028] FIG. 1 is a perspective view showing an attachment device (1) and an electronic device (2) according to one embodiment of the present disclosure.

[0029] FIG. 2 is a perspective view showing a first frame (20) and a bendable member (100) included in an attachment device (1) according to one embodiment of the present disclosure.

[0030] Referring to FIGS. 1 and 2, the electronic device (2) may be used collectively to refer to various types of user terminals including a display. The electronic device (2) may include portable communication devices such as smartphones and portable multimedia devices such as tablet PCs. The display may include various types of displays, including rigid displays and flexible displays (e.g., foldable displays). The display may include a touch panel or a cover window at the top to protect the display panel.

[0031] According to one embodiment, the cover window may be damaged or broken due to physical impact, such as impact or dropping, applied to the display, which may result in a deterioration in the quality of the display due to damage to the touch panel and display panel, and may cause the electronic device (1) to malfunction. In addition, damage or breakage of the cover window may cause the surface to become sharp, which may cause injury to the user. Therefore, the user may attach a protective film to the front of the cover window for use.

[0032] Hereinafter, in this document, "x-axis direction", "y-axis direction", and "z-axis direction" may be defined as follows. The x-axis direction may be defined as the left direction when the electronic device (2) is viewed from the front (e.g., the direction in which the display is placed). The y-axis direction may be defined as the downward direction when the electronic device (2) is viewed from the front. The z-axis direction may be defined as the upward direction of the electronic device (2). However, in this document, "front-back direction", "left-right direction", and "up-down direction" may be used based on the illustrated drawings, and the shape and position of each component are not limited thereby. For example, when the bendable member (100) included in the attachment device (1) is taken as a reference, the upper side of the bendable member (100) may be understood as the +z-axis direction, and the lower side of the bendable member (100) may be understood as the -z-axis direction.

[0033] According to one embodiment, when a user directly attaches a protective film to the front of a cover window without a separate guide device, it may not be easy to align the protective film with the display. The attachment device (1) described below may be understood as a device for easily attaching the display and the protective film in an aligned state, and the attachment device (1) may include a bendable member for effectively reducing tension generated when attaching the protective film.

[0034] According to one embodiment, the attachment device (1) may be understood as a fixing device or a guide device for facilitating attachment of a film assembly (e.g., film assembly (200) of FIG. 5) attached to the front of the electronic device (2) to protect the display of the electronic device. The attachment device (1) may be understood as an attachment kit composed of a plurality of components.

[0035] According to one embodiment, the attachment device (1) can be positioned on one side and the other side of the electronic device (2) to fix the electronic device (2). The attachment device (1) can include a bendable member (100) that is positioned in the height direction (e.g., the z-axis direction) and is configured to bend in a predetermined direction by an external force applied when attaching a protective film (210) (e.g., the protective film (210) of FIG. 5).

[0036] According to one embodiment, the attachment device (1) may include a first frame (20) and a second frame (20-1). The first frame (20) and the second frame (20-1) may be positioned so as to be positionable on one side and the other side of the electronic device (2). The first frame (20) may be positionable on the upper side of the electronic device (2), and the second frame (20-1) may be positionable on the lower side of the electronic device (2).

[0037] According to one embodiment, the first frame (20) and the second frame (20-1) may have the same shape. Since the first frame (20) and the second frame (20-1) have the same shape, the cost of manufacturing the attachment device (1) can be reduced. Since the first frame (20) and the second frame (20-1) have the same shape, the description of the shape of the first frame (20) described in this document may be applied to the second frame (20-1).

[0038] According to one embodiment, the first frame (20) and the second frame (20-1) may be manufactured from synthetic resin (or plastic). The first frame (20) and the second frame (20-1) may be manufactured by injection molding.

[0039] According to one embodiment, the first frame (20) may include a mounting portion (41, 43) and an extension portion (30) extending in the -y-axis direction from the mounting portion (41, 43). The mounting portion (41, 43) may be configured to allow at least a portion of the side frame to be mounted when the electronic device (2) is fixed to the attachment device (1).

[0040] According to one embodiment, the mounting portions (41, 43) may include a first mounting portion (41) and a second mounting portion (43). The first mounting portion (41) may come into contact with the upper frame of the electronic device (2) when the electronic device (2) is fixed, and the second mounting portion (43) may come into contact with at least a portion of the left frame of the electronic device (2) when the electronic device (2) is fixed.

[0041] According to one embodiment, the extension (30) may include a joining hole (31) and joining protrusions (33, 34). The joining hole (31) may provide a space for the bendable member (100) to be joined, which will be described later. The joining protrusions (33, 34) may be used to join and secure the film assembly (200) to a frame (e.g., the first frame (20) or the second frame (20-1)).

[0042] According to one embodiment, the coupling protrusions (33, 34) may include a first coupling protrusion (33) and a second coupling protrusion (34). The coupling protrusions (33, 34) may be positioned on both sides of the coupling hole (31). The first coupling protrusion (33) and the second coupling protrusion (34) may have different shapes. Since the first coupling protrusion (33) and the second coupling protrusion (34) have different shapes, when the film assembly (200) is fixed to the attachment device (1), the user may be guided to easily align the display and the film assembly (200).

[0043] According to one embodiment, the attachment device (1) may include a bendable member (100). The bendable member (100) may be arranged to be selectively coupled to either the first frame (20) or the second frame (20-1). Hereinafter, it will be assumed that the bendable member (100) is coupled to the first frame (20).

[0044] According to one embodiment, the bendable member (100) can be coupled with a fastening hole (31) of the first frame (20). The fastening hole (31) can have a shape corresponding to a leg (e.g., leg (130) of FIG. 2 or 3) located on the lower side of the bendable member (100). The bendable member (100) can be coupled to the fastening hole (31) by a fitting or force-fitting method.

[0045] In one embodiment, the bendable member (100) may be composed of a synthetic resin (or plastic). The bendable member (100) may be manufactured by injection molding.

[0046] According to one embodiment, the bendable member (100) may include a head (110), a body (120), and legs (130).

[0047] According to one embodiment, the body (120) can be bent by an external force so that the bendable member (100) is bent in a predetermined direction. The body (120) can include a plurality of stoppers (121) and a plurality of slits (123) arranged between adjacent stoppers (121) among the plurality of stoppers (121). The body (120) can be easily bent in a predetermined direction by the stoppers (121) and the slits (123), and can be bent by a critical range.

[0048] According to one embodiment, the head (110) may be positioned on the upper side of the body (120). The head (110) may include a first part (111) and a second part (113) positioned on the lower side of the first part (111). When one side of the film assembly (200) (e.g., the first guide film (220) of FIG. 5) is coupled to the bendable member (100), the first part (111) may provide a function of a catch for fixing the first guide film (220).

[0049] According to one embodiment, one edge of the first portion (111) may be chamfered. For example, since the edge located at the rear of the first portion (111) is chamfered, the first portion (111) may have a generally trapezoidal shape. Since one edge of the first portion (111) is chamfered, when the protective film (210) is completely attached to the display, the film assembly (200) can be easily detached from the first portion (111).

[0050] According to one embodiment, the leg (130) may be positioned on the lower side of the body (120). When the bendable member (100) is coupled to the first frame (20), at least a portion of the leg (130) may be coupled to the fastening hole (31) of the first frame (20). At least a portion of the leg (130) may be coupled to the fastening hole (31) by a fitting or force fitting, and may be coupled by various other methods.

[0051] According to one embodiment, the second frame (20-1) may have the same shape as the first frame (20). The second frame (20-1) may include a mounting portion (41-1, 43-1) and an extension portion (30-1) extending in the y-axis direction from the mounting portion (41-1, 43-1). The extension portion (30-1) may include a fastening hole (31-1) and engaging protrusions (33-1, 34-1) located on both sides of the fastening hole (31-1).

[0052] FIG. 3 is a side view of a bendable member (100) (e.g., the bendable member (100) of FIG. 1) according to one embodiment of the present disclosure.

[0053] FIG. 4 is a side view showing a bendable member (100) before and after bending according to one embodiment of the present disclosure. That is, it can be understood that the state indicated by the dotted line represents the state of the bendable member (100) before bending, and the state indicated by the solid line represents the state of the bendable member (100) after bending.

[0054] FIGS. 3 and 4 may be understood as side views of the bendable member (100) illustrated in FIG. 1 or FIG. 2 viewed from left to right (e.g., in the -x-axis direction). The embodiments of FIGS. 3 and 4 may be optionally combined with the embodiments of FIGS. 1 and 2.

[0055] Referring to FIG. 3, the bendable member (100) may include a head (110), a body (120), and legs (130). The bendable member (100) may include an elastic material so as to be bent in a predetermined direction by an external force. For example, when a film assembly (e.g., a film assembly (200) of FIG. 5) is attached to an electronic device (e.g., an electronic device (2) of FIG. 1), the bendable member (100) coupled to the first frame (20) may be bent from the first frame (20) toward the second frame (e.g., the second frame (20-1) of FIG. 1). By operating the bendable member (100) to be bent in a predetermined direction, the tension generated when a protective film (210) (e.g., a protective film (210) of FIG. 5) is attached can be reduced.

[0056] According to one embodiment, the body (120) may include a plurality of stoppers (121) arranged in the height direction and slits (123) positioned between adjacent stoppers (121) among the plurality of stoppers (121). The plurality of stoppers (121) and the plurality of slits (123) may be arranged in the height direction (e.g., the z-axis direction), and the plurality of stoppers (121) and the plurality of slits (123) may be arranged alternately.

[0057] According to one embodiment, the plurality of slits (123) can facilitate the body (120) from being deformed in a predetermined direction, and the plurality of stoppers (121) can prevent the body (120) from being excessively bent or broken when deformed in the predetermined direction.

[0058] According to one embodiment, a plurality of slits (123) may be formed by removing at least a portion of the body (120). The plurality of slits (123) may be formed in the front (e.g., in the y-axis direction) of the body (120). The slits (123) may include an open end located in the front of the bendable member (100) and a fixed end located in the rear (e.g., in the y-axis direction) of the bendable member (100). Without being limited to what is illustrated, the slits (123) may be formed in the front and / or rear of the body (120), and when the slits (123) are formed in the rear of the body (120), the open end of the slits (123) may be located in the rear of the body (120).

[0059] According to one embodiment, the bendable member (100) may have a predetermined height (h). The body (120) may have a height (h1) that has a predetermined ratio to the height (h) of the bendable member (100). For example, h and h1 may satisfy the relationship h1≥0.8*h. Since the height (h1) of the body (120) has a predetermined ratio to the height (h) of the bendable member (100), the bendable member (100) may be prevented from being detached when coupled to the first frame (20).

[0060] According to one embodiment, the stopper (121) and the slit (123) may have a predetermined thickness in the height direction (e.g., z-axis direction) and a predetermined width in the width direction (e.g., y-axis direction).

[0061] According to one embodiment, the stopper (121) may have a height t1 in the height direction and a thickness d1 in the width direction. The slit (123) may have a height t2 in the height direction and a thickness d2 in the width direction. The thickness d1 of the stopper (121) may be substantially the same as the thickness of the body (120), and the thickness d2 of the slit (123) may be relatively smaller than the thickness d1 of the stopper (121). The height t1 of the stopper (121) may be relatively larger than the height t2 of the slit.

[0062] According to one embodiment, the degree of deformation caused by an external force applied to the bendable member (100) can be determined corresponding to the height t1 and thickness d1 of the stopper (121) and the height t2 and thickness d2 of the slit (123).

[0063] For example, as the thickness d2 of the slit (123) increases, deformation of the body (120) can easily occur, and thus the function of attenuating the tension generated by the external force applied to the bendable member (100) can be strengthened. However, if the thickness d2 of the slit (123) becomes excessively large, there is a possibility that the body (120) may be damaged by the external force applied to the bendable member (100). Therefore, the thickness d2 of the slit (123) can be set to a level of 65% to 85% of the height d1 of the stopper (121), and d2 and d1 can be set to have the following relationship: 0.65≤d2 / d1≤0.85

[0064] For example, as the height h2 of the slit (123) increases, deformation of the body (120) can easily occur, so that the function of reducing tension generated by external force applied to the bendable member (100) can be strengthened. However, if the height h2 of the slit (123) becomes excessively large, there is a possibility that the body (120) may be damaged by external force applied to the bendable member (100). Therefore, the height h2 of the slit (123) can be set to have the following relationship with the height h1 of the stopper (121): 0.3≤h2 / (h1+h2)≤0.4

[0065] Referring to FIG. 4, the bendable member (100) can be bent or bent in a predetermined direction by an external force applied according to the attachment of the protective film (e.g., the protective film (210) of FIG. 5). For example, the bendable member (100) can be bent or bent in the direction from the first frame (e.g., the first frame (20) of FIG. 1) to the second frame (e.g., the second frame (20-1) of FIG. 1). Alternatively, when an attachment device (e.g., the attachment device (1) of FIG. 1) is fixing an electronic device (e.g., the electronic device (2) of FIG. 1), the bendable member (100) can be bent or bent in the direction from the upper frame of the electronic device (1) to the lower frame.

[0066] According to one embodiment, the bendable member (100) can be bent by a predetermined angle (θ) by an external force. For example, the bendable member (100) can be bent forward (e.g., in the y-axis direction in FIG. 1 or 2) with respect to a central axis direction (e.g., in the z-axis direction) coupled with the first frame (20). Here, the predetermined angle (θ) can be defined as the angle between an extension line (s1) before bending and an extension line (s2) after bending based on an extension line connecting the highest point of the head (110) and the lowest point of the body (120).

[0067] For example, the predetermined angle (θ) may be 20° to 30°. Since the bendable member (100) is bent by the predetermined angle, the attachment device (1) can maintain a constant tension generated when attaching the protective film (210), and thus, the angle of inclination between the protective film (210) and the display of the electronic device (2) can be maintained constant while attaching the protective film (210).

[0068] According to one embodiment, when the bendable member (100) is bent, the ends of adjacent stoppers (121) among the plurality of stoppers (121) may contact each other. When the bendable member (100) is bent to the maximum, the ends of adjacent stoppers (121) may contact each other, thereby allowing the bendable member (100) to bend within a preset range. As the bendable member (100) is bent, the shape of the slit (123) may be deformed. For example, as the bendable member (100) is bent, the shape may be deformed such that the size of the slit (123) is reduced.

[0069] According to one embodiment, the bendable member (100) may have various shapes other than those illustrated in FIGS. 3 and 4. In this regard, this will be described with reference to FIGS. 9a to 10b.

[0070] FIG. 5 is a perspective view illustrating an attachment device (1) (e.g., attachment device (1) of FIG. 1), an electronic device (2) (e.g., electronic device (2) of FIG. 2), and a film assembly (200) according to one embodiment of the present disclosure.

[0071] FIG. 6 is a side view of an attachment device (1), an electronic device (2), and a film assembly (200) according to one embodiment of the present disclosure, viewed from one direction. FIG. 6 may be understood as a side view of FIG. 5.

[0072] At least some of the configurations illustrated in FIGS. 5 and 6 may correspond to those illustrated in FIGS. 1 to 4. Therefore, overlapping descriptions will be omitted and the differences will be primarily explained.

[0073] The embodiments of FIGS. 5 and 6 can be optionally combined with the embodiments of FIGS. 1 to 4.

[0074] Referring to FIGS. 5 and 6, the film assembly (200) may include a protective film (210) corresponding to a display of the electronic device (2), a first guide film (220) positioned on an upper side of the protective film (210), and a second guide film (230) positioned on a lower side of the protective film (210). The first guide film (220) and the second guide film (230) may secure the film assembly (200) to the attachment device (1) so that the protective film (210) is aligned with the display. The first guide film (220), the protective film (210), and the second guide film (230) may be integrally formed to form the film assembly (200).

[0075] According to one embodiment, the film assembly (200) can be fixed to the attachment device (1). For example, the first guide film (220) can be fixed to the head (110) of the bendable member (100), and the second guide film (230) can be fixed to the coupling protrusions (33-1, 34-1) of the second frame (20-1). To this end, the first guide film (220) can have an opening formed at a position corresponding to the shape of the first part (e.g., the first part (111) of FIG. 3) of the head (110), and the second guide film (230) can have an opening formed at a position corresponding to the shape of the coupling protrusions (33-1, 34-1).

[0076] According to one embodiment, due to the openings formed in the first guide film (220) and the second guide film (230), when a user attaches the protective film (210), the display of the electronic device (2) and the protective film (210) can be easily aligned.

[0077] According to one embodiment, when the film assembly (200) is secured to the attachment device (1), the film assembly (200) may be positioned to be inclined with respect to the electronic device (2) or a floor surface (e.g., an xy plane).

[0078] Although not shown, the film assembly (200) may be configured by stacking at least a plurality of layers. For example, the film assembly (200) may be configured by three layers. The layer where the film assembly (200) is substantially attached to the display of the electronic device (2) will be referred to as the first layer. The film assembly (200) may include the first layer, a second layer disposed on the back surface of the first layer, and a third layer disposed on the front surface of the first layer. The second layer and the third layer may protect the first layer from physical damage, such as scratches. The first and second layers may have, for example, an area as large as the protective film (210), and the third layer may have, for example, an area substantially the same as the entire film assembly (200).

[0079] For example, the film assembly (200) illustrated in FIGS. 5 and 6 can be understood as having the second layer located on the back surface of the first layer removed. In the state illustrated in FIGS. 5 and 6, a user can attach a protective film (210) using a squeegee member (e.g., the squeegee member (300) of FIGS. 7 and 8). The process of attaching the protective film (210) to the electronic device (2) will be described below with reference to FIGS. 7 and 8.
