Japanese Unexamined Patent Publication No. 2004-39327 (page 5-7, FIG. 4)

  Here, the conventional folding cellular phone has no characteristic parts on the back, and the back of the housing is not an important part of the design. In addition, a display screen such as a large liquid crystal screen is also provided on the back side, and since this display screen is a part that is noticed by the user, the back side of the housing has also become an important part in design. Therefore, in order to differentiate the mobile phone, it is necessary to devise a high-class feeling on the back of the housing, but the mobile phone housing is usually made of plastic or the like because of the demand for weight reduction, It is difficult to improve design because plastic cannot give a high quality texture.

  In addition, in the case of a foldable mobile phone equipped with a digital camera function, an optical system such as a lens of a photography mechanism is arranged on the back of the housing in addition to a large display screen. Lenses and other parts are easily scratched and have low mechanical strength, so they must be reliably protected. In particular, mobile phones are often carried around while being worn, and a large force is easily applied. Therefore, a structure that effectively protects easily damaged parts such as the display screen and the lens of the photographing mechanism is required.

  In addition, since the mobile phone is used by being directly touched, it is necessary to devise a structure in consideration of safety so as not to hurt the user.

  Thus, when designing a mobile phone, it is necessary to devise ways to improve the design of the back side on which parts that are noticed by the user, such as the display screen, are arranged. It is necessary to effectively protect the parts that are easily damaged, and it is also necessary to consider safety so as not to hurt the user, and there is a proposal of a mobile phone that can satisfy such a demand. It is desired.

  The present invention has been made in view of the above problems, and its main purpose is excellent in design, effectively protecting easily damaged parts such as a display screen and a lens, and ensuring safety. It is to provide a mobile phone that can be used.

  In order to achieve the above object, in the mobile phone of the present invention, the first casing and the second casing are held so as to be openable and closable by a hinge, and are opposed to the second casing of the first casing. A folding structure mobile phone having a display screen on both the inner surface and the back surface opposite to the inner surface, a metal plate covering at least the periphery of the display screen is disposed on the back surface of the first housing, The metal plate is disposed so as to be depressed with respect to the first casing in the vicinity of the metal plate.

  In the mobile phone of the present invention, the first casing and the second casing are held so as to be openable and closable by a hinge, and an inner surface of the first casing facing the second casing and the inner surface In a cellular phone with a folding structure that includes a display screen on both the back surface opposite to the first housing and an optical system of a photography mechanism on the back surface of the first housing, on the back surface of the first housing, A metal plate covering at least the periphery of the display screen and the optical system is disposed, and the metal plate is disposed so as to be recessed with respect to the first casing in the vicinity of the metal plate. It is.

  In this invention, the said metal plate can be set as the structure arrange | positioned so that it may become a state depressed also with respect to the said display screen near this metal plate, or the said display screen and the said optical system.

  Moreover, in this invention, the edge part of the outer peripheral part of the said metal plate can be set as the structure bent by the said 1st housing | casing side, The position which opposes the said edge part of the said 1st housing | casing In addition, a groove capable of storing the bent metal plate may be formed.

  Moreover, in this invention, it can also be set as the structure by which the at least one edge part of the opening part or notch part provided in the said metal plate is dropped into the said 1st housing | casing side.

  Moreover, in this invention, it is preferable that the said metal plate is fixed to the said 1st housing | casing with a double-sided tape, and the said metal plate is comprised so that attachment or detachment is possible.

  As described above, according to the configuration of the present invention, the metal plate is disposed around the display screen disposed on the back surface of the mobile phone having the folding structure, the lens of the photographing mechanism, and the like, thereby enhancing the texture and improving the design. In addition, the metal plate can effectively protect easily damaged parts such as a display screen and a lens, and the metal plate can be disposed so as to be recessed with respect to surrounding members. The safety can also be ensured by dropping or bending the end of the metal plate to the housing side.

  As described above, according to the mobile phone having the folding structure of the present invention, the following effects can be obtained.

  The first effect of the present invention is that the design of a mobile phone can be improved. The reason is that the vicinity of the parts that are noticed by the user, such as the display screen, is an important part of the design, and by placing a metal plate made of aluminum or aluminum alloy on this part, the texture of the entire mobile phone This is because it can enhance the quality and create a sense of quality. Moreover, since this metal plate is detachably fixed by a double-sided tape or the like, it can be replaced with any metal plate according to the user's preference.

  In addition, the second effect of the present invention is that it is possible to effectively protect components that are easily damaged. The reason is that by placing a metal plate around perishable parts such as a display screen such as a liquid crystal screen or a lens of a photography mechanism, these parts can be prevented from being damaged even when a strong force is applied. Because it can.

  The third effect of the present invention is that a highly secure mobile phone can be provided. The reason is that the metal plate is not simply arranged around the display screen or the lens of the photography mechanism, but the metal plate is arranged so as to be depressed with respect to a member such as a housing in the vicinity thereof, Further, the end of the metal plate, such as the outer periphery, opening, and notch, is dropped or bent in the direction of the casing, so that even if the user contacts the metal plate, there is no risk of damaging the user.

  As shown in the prior art, a recent mobile phone has a display screen on the back of the housing, and a portion in the vicinity of a part that is noticed by the user such as this display screen is important in terms of design. Since it is a part, it is important to improve the design of the back surface in order to differentiate it from other mobile phones. Further, since easily damaged parts such as a display screen and a lens of a photographing mechanism are exposed on the back surface of the mobile phone, it is also important to protect these parts effectively. Furthermore, it is necessary to ensure safety so as not to hurt the user in any use form.

  Here, a structure in which a metal material is used in order to improve the designability or protect a component that is easily damaged can be considered. However, if a metal material is placed in various places, the weight of the mobile phone increases, and a strong member such as a metal material may damage a user depending on the structure.

  Therefore, the present inventor does not use a lot of metal members, but is an easily noticeable part of the design in the mobile phone, and the metal plate is disposed only around the easily damaged part, In addition, the metal plate is not simply disposed, but is disposed so as to be recessed with respect to the members in the vicinity thereof, and the end portions such as the outer peripheral portion, the opening portion, and the cutout portion of the metal plate are provided. By carrying out processing such as dropping or bending the case, it is possible to effectively protect easily damaged parts and realize a mobile phone that ensures safety.

  Conventionally, decorative boards such as aluminum have been used as decoration methods for TVs, audio equipments, etc., but since these equipments are installed and used, the weight limit is not strict. In addition, since it is difficult to consider that a large force is applied to the device, the decorative board is designed only considering design. Therefore, even if this decorative board is applied to a mobile phone, the above problems cannot be solved, and all the above problems can be solved only by the structure of the present invention.

  In order to describe the above-described embodiment of the present invention in more detail, a cellular phone including a metal plate according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a structure of a mobile phone according to an embodiment of the present invention, FIG. 2 is a sectional view and a partially enlarged view taken along line AA, and FIG. 3 is a sectional view taken along line BB. FIG. 4 is a perspective view showing a state in which the metal plate of the cellular phone according to the present embodiment is removed, FIG. 5 is a cross-sectional view of the upper housing taken along the line CC, and FIG. It is sectional drawing of the upper side housing | casing in a line. Moreover, FIG. 7 is a top view which shows the variation of the structure of the metal plate of a present Example.

  As shown in FIG. 1, a cellular phone 1 having a folding structure according to the present embodiment includes a liquid crystal display element that displays a standby screen, various function setting screens, a web screen, etc. on one housing (upper housing 2). And a display screen formed with EL light-emitting elements, etc., and a photo shooting mechanism for taking still images and moving images, etc. The other housing (lower housing 3) has numeric keys, direction keys, and special functions. A key operation unit in which a plurality of keys such as keys are arranged, a wireless communication unit that performs telephone communication, mail transmission / reception, web screen reception, TV broadcast reception, etc., an internal storage device that stores various setting values, A control unit for controlling the function is provided.

  Here, the conventional folding cellular phone is not provided with any characteristic parts on the back surface of the upper housing 2 (the surface opposite to the inner surface (inner surface) in the folded state). It was not an important part. However, recent cellular phones 1 have a large display screen on the back of the upper housing 2 so that the contents of the e-mail can be confirmed even when the upper housing 2 and the lower housing 3 are closed. Since the display screen is a part that is noticed by the user, the back surface of the upper housing 2 is also an important part in the design, and a device for improving the design of the back surface is required. .

  Further, in a cellular phone with a folding structure having a function of a digital camera, an optical system such as a lens of a photography mechanism is disposed on the back surface of the upper housing 2 together with the display screen, but these components are easily damaged. In addition, a rear display unit cover 6 is provided on the surface of the display screen, and a camera cover 5 is also provided on the surface of an optical system such as a lens of a photography mechanism. However, such a cover is intended to prevent damage when the above parts come into contact with other articles, and the cover itself is made of plastic, glass, etc., so when a large force is applied However, these parts cannot be adequately protected. Further, a structure in which the housing itself is formed of metal or the like to protect the above parts is conceivable. However, if a large amount of metal is used, the mobile phone 1 cannot be reduced in weight, which is not preferable.

  Therefore, in the mobile phone 1 of the present embodiment, attention is paid to the design so that the design can be improved, the easily damaged parts can be effectively protected, and the increase in weight can be suppressed as much as possible. A plate-like metal plate 4 made of aluminum or aluminum alloy is attached only around parts that are easily damaged (especially in the vicinity of the rear display screen or the lens of the photo shoot mechanism), creating a sense of quality through the metal texture. In addition to functioning as a decorative member that improves design, the metal plate functions as a protective member.

  The metal plate 4 is not limited to the shape shown in the drawing as long as it has at least a shape that covers the periphery of a component that is noticeable and easily damaged. Further, the material of the metal plate 4 is not limited to aluminum or aluminum alloy, but may be any metal material that is lightweight, high in strength and inexpensive, and the thickness of the metal plate 4 is not particularly limited, and functions as a protective member. Any thickness can be used.

  Further, the surface form of the metal plate 4 is not particularly limited as long as it can realize a high-class feeling and differentiation that cannot be realized by finishing plastic or the like depending on the texture. For example, the surface of the metal plate 4 is smoothed and glossy. Alternatively, a minute unevenness may be provided on the surface of the metal plate 4 to make it matt, or the surface of the metal plate 4 may be painted or a pattern may be formed. In addition, when the surface of the metal plate 4 is in a glossy state, the visibility of the display screen may be deteriorated. In that case, for example, as shown in FIG. 7, a variation such as providing a matte part 10 in an area near the display screen on the back and making the other area a glossy part 9 to give a high-class feeling is possible. .

  Also, the metal plate 4 fixing structure is not particularly limited, but the metal plate 4 needs to be prevented from being easily detached by vibration or impact, and the surface of the metal plate 4 is scratched or the user can Since it may be possible to replace another metal plate 4, it is preferable to have a detachable fixing structure. For example, it may be configured to be attached to the upper housing 2 with an adhesive member such as a double-sided tape. it can.

  Here, unlike the key operation unit, the display screen on the back and the lens of the photography mechanism are not directly touched by the user, but the mobile phone 1 is often carried around and worn on the body. It is necessary to consider safety so that the user is not accidentally injured when touched. Therefore, in the mobile phone 1 of the present embodiment, the metal plate 4 is not simply attached to a predetermined position of the upper housing 2, but the surface of the metal plate 4 is made of another member (see FIG. 2 and FIG. 3). The upper housing 2, the rear display unit cover 6, the lens cover 5, etc.) are recessed.

  More specifically, as shown in FIG. 2A, the metal plate 4 of this embodiment is formed so as to partially contact the end of the rear display unit cover 6 and press the rear display unit cover 6. However, the metal plate 4 is formed so that the periphery of the rear display unit cover 6 is thin and the upper plate 2 and the rear display unit cover 6 are recessed with the metal plate 4 attached. The mounting structure and thickness are set. Further, as shown in FIG. 3, the mounting structure and thickness are set so that the metal plate 4 is also recessed with respect to the camera cover 5. In addition, the metal plate 4 should just be arrange | positioned so that it may be in the state where it was depressed with respect to the upper side housing | casing 2 of this metal plate 4 vicinity. Further, the metal plate 4 only needs to be disposed so as to be in a depressed state with respect to the members in the vicinity thereof. However, if the metal plate 4 is excessively depressed, the function as a protective member cannot be performed. Then, as shown in FIG. 2B, the surface of the metal plate 4 is set to be approximately 0.3 mm lower than the surface of the upper casing 2 in the vicinity thereof and approximately 0.2 mm lower than the rear display unit cover 5. The metal plate 4 can function as a protective member.

  In this way, the metal plate 4 is arranged so as to be recessed with respect to the members in the vicinity of the metal plate 4 (the upper housing 2 or the upper housing 2, the rear display unit cover 6, and the camera cover 5). Thus, the risk of hurting the user can be avoided, but the user may be hurt by the edge of the end of the metal plate 4 when the mobile phone 1 is strongly pressed against the body. Therefore, in the cellular phone 1 according to the present embodiment, not only the unevenness relationship between the surface of the metal plate 4 and the members in the vicinity thereof is taken into account, but also the occurrence of the above problem occurs by applying predetermined processing to the end of the metal plate 4. Also avoid.

  More specifically, as shown in FIG. 4A, the metal plate 4 has an opening for the rear display unit cover 6, an opening for the camera cover 5, an opening for the incoming LED lens 7, a camera light. A notch for the lens 8 is provided, and if the human body comes into contact with the end of the metal plate 4 (the outer periphery of the metal plate 4, the opening, the notch, etc.), the user may be injured. Therefore, a structure (see FIG. 2 (b)) in which the end is dropped into the inside (upper housing 2 side) with respect to the opening or notch of the metal plate is provided, and the outer periphery of the metal plate 4 is provided. On the other hand, a structure (see FIG. 2B) is provided in which the end is bent inward (upper housing 2 side).

  Further, in order to realize the above bending structure, as shown in FIGS. 5 and 6, the upper housing 2 is also provided with a groove 2a for allowing the end of the metal plate 4 to escape, and the above dropping structure is realized. In addition, as shown in FIGS. 2 and 3, a recess for allowing the end of the metal plate 4 to escape is also provided on the outer periphery of the rear display unit cover 6 and the camera cover 5. The groove 2a and the recess may have any shape that can release the dropping structure or the folding structure of the metal plate 4, and may be larger than the dropping structure or the bending structure of the metal plate 4. A groove 2a for fitting with the folding structure of the plate 4 may be provided. In the case of the fitting structure, the metal plate 4 can be fixed to the upper housing 2, and thus a fixing member such as a double-sided tape is omitted. Can do.

  As described above, in the present embodiment, among the components of the mobile phone 1, a metal made of aluminum or aluminum alloy around the components such as the rear display screen and the lens which are easily noticed and easily damaged. The plate 4 is fixed with a double-sided tape and the like, and the surface of the metal plate 4 is disposed so as to be recessed with respect to a nearby member. Further, the outer peripheral portion, opening, notch, etc. of the metal plate 4 By dropping or bending the end of the metal plate 2 toward the inner housing 2, the texture of the metal plate 4 improves the design and improves the design that can not be realized by finishing plastic, etc. It is possible to realize a mobile phone 1 that effectively protects easily damaged members and further sufficiently enhances safety.

  In the above embodiment, the metal plate 4 is provided around the rear display screen and the lens unit. However, the metal plate 4 is exposed on the surface of the mobile phone 1 and is arranged so as to cover at least a part of the member that is easily noticed and easily damaged. It only has to be installed. In the above embodiment, the case where one metal plate 4 is provided is shown. However, two or more metal plates 4 (for example, a first metal plate around the rear display unit and a second metal plate around the lens, etc.). ) May be provided individually. Further, in the present embodiment, the cellular phone having the folding structure has been described, but the present invention is not limited to the above-described embodiment, and can be similarly applied to a straight-type cellular phone.
