Description

  The present invention relates to an electronic device.

  In recent years, various built-in parts are mounted on many electronic devices. Specifically, for example, a mobile phone incorporates a camera or the like that provides an imaging function independent of the call function.

  With such built-in components, the electronic device can provide various functions. That is, in the example of the mobile phone described above, the user can not only make a call using the mobile phone but also acquire, store, and transmit an image.

  In such an electronic device, in order to mount a built-in component, a housing is formed in accordance with the shape of the component. That is, for example, in a mobile phone equipped with a camera, the case of the mobile phone is formed in accordance with the shape of the camera, and the camera is fixed to the case.

  By the way, parts such as cameras may vary in size depending on the specifications. Specifically, for example, the larger the number of pixels that can be captured, the larger the size of the camera. For this reason, when a component is incorporated in an electronic device, a casing that conforms to each specification of the component is formed. Therefore, even if the mobile phone has the same call function and the same appearance design, if the size of the components to be incorporated is different, separate housings that match the size of the components are molded. Is done.

  However, when the built-in parts are different, forming the housing separately according to the size of each part has a problem that the manufacturing cost increases and is not efficient. For example, when manufacturing two types of mobile phones that differ only in camera specifications and share other functions and designs, for example, molds are prepared by preparing different molds for each model. Therefore, the manufacturing process cannot be made common, which is inefficient.

  The disclosed technique has been made in view of the above points, and an object thereof is to provide an electronic device capable of improving the efficiency of the manufacturing process.

An electronic device disclosed in the present application is, in one aspect, an electronic device having a housing case and a component , wherein the housing case includes two plane portions intersecting each other at a predetermined angle, and the two planes. a bottom surface portion that intersects both the predetermined angle section is fixed at a position opposite to the two flat portions, and a spring portion having elasticity to expand and contract in a direction toward the two flat portions and the bottom portion, the And the component is pressed in the direction of the two flat portions by the elastic elastic force of the spring portion and pressed in the direction of the bottom portion, and both the two flat portions and the bottom portion Abut .

  According to one aspect of the electronic device disclosed in the present application, it is possible to increase the efficiency of the manufacturing process.

  Hereinafter, an embodiment of an electronic device disclosed in the present application will be described in detail with reference to the drawings. In the present embodiment, a mobile terminal device such as a mobile phone will be described as an example of an electronic device, but the present invention is not limited to this embodiment.

  FIG. 1 is a diagram illustrating an appearance of a mobile terminal device 100 according to the present embodiment. A mobile terminal device 100 shown in FIG. 1 is a so-called foldable mobile phone, and has a configuration in which a movable-side casing case 101 and a fixed-side casing case 102 are connected via a hinge.

  The movable housing case 101 is formed using, for example, a resin or the like, and components such as an imaging camera 103 are incorporated therein. The camera 103 is an imaging component, is fixed inside the movable housing case 101, and is covered with an exterior panel 104. The exterior panel 104 is transparent without being colored in the portion covering the lens of the camera 103, and enables imaging by the camera 103. A substantially rectangular opening is provided in the center of the exterior panel 104, and a liquid crystal panel 105 for displaying various information is disposed in the opening.

  On the other hand, operation keys 106 used for various operations such as inputting a telephone number are arranged on the fixed housing case 102. The operation key 106 is also used for imaging by the camera 103, switching of display on the liquid crystal panel 105, and the like. That is, the user presses the operation key 106 to perform various operations on the mobile terminal device 100.

  FIG. 2 is a diagram showing the movable casing case 101 of the mobile terminal device 100. As shown in FIG. 2, a camera fixing unit 201 for incorporating the camera 103 is formed in the movable housing case 101. That is, a through hole is formed in a part of the movable housing case 101, and the camera 103 is in contact with and fixed to the inner wall surface of the through hole. Further, the through hole formed in the movable housing case 101 is covered with the exterior panel 104 on the lens side of the camera 103. Therefore, the position of the camera 103 is fixed by contacting the inner wall surface of the through hole and one surface of the exterior panel 104.

  A spring portion that presses the camera 103 toward the inner wall surface of the through hole and one surface of the exterior panel 104 is formed at one corner of the through hole. As will be described in detail below, by adopting a structure in which the camera 103 is pressed by this spring portion, it is possible to incorporate it into one common movable casing case 101 even if the camera size is different.

  FIG. 3 is a perspective view illustrating a configuration of the camera fixing unit 201 according to the present embodiment. As shown in FIG. 3, a through-hole is formed in a part of the movable housing case 101, and the inner wall surface 301 and the inner wall surface 302 adjacent to each other of the through-holes intersect each other vertically. One opening of the through hole is covered with the exterior panel 104, and the bottom surface 303 of the camera fixing portion 201 is formed by one surface of the exterior panel 104 covering the through hole. That is, the camera fixing portion 201 is a concave portion having the inner wall surface of the through hole as a side surface and one surface of the exterior panel 104 as a bottom surface. And in this recessed part, the inner wall surface 301, the inner wall surface 302, and the bottom face 303 cross | intersect mutually perpendicularly | vertically.

  In addition, a spring portion 304 is integrally formed with the movable housing case 101 at a diagonal angle where the inner wall surface 301 and the inner wall surface 302 intersect. The spring portion 304 has an inverted U-shape as a whole, and has elasticity that expands and contracts in a direction toward the corner where the inner wall surface 301 and the inner wall surface 302 intersect. Then, the spring portion 304 presses the camera 103 in the direction of the angle where the inner wall surface 301 and the inner wall surface 302 intersect by elastic force generated by elasticity. For this reason, the camera 103 contacts the inner wall surface 301 and the inner wall surface 302, and the position is fixed. By providing such a spring portion 304, even a camera having a size different from that of the camera 103 can be fixed to the camera fixing portion 201.

  FIG. 4 is a schematic diagram showing a cross section taken along the line II shown in FIG. As shown in FIG. 4, the exterior panel 104 is attached to the movable housing case 101 with a double-sided tape 401. As a result, the inner wall surface 301 and inner wall surface 302 of the through hole formed in the movable housing case 101 and the bottom surface 303 formed by one surface of the exterior panel 104 divide a recess serving as the camera fixing unit 201. A spring portion 304 extends from the movable housing case 101 at a diagonal angle where the inner wall surface 301 and the inner wall surface 302 intersect.

  Specifically, the spring part 304 includes a support plate part 402, a bending part 403, a flat part 404, and a pressing part 405 in order from the end of the movable housing case 101. The support plate unit 402 rises vertically from the end of the movable housing case 101 to the bottom surface 303 and supports the entire spring unit 304. The support plate portion 402 is a plate-like portion having a sufficient length in a direction perpendicular to the bottom surface 303 so that the base connected to the end portion of the movable housing case 101 is deformed to generate an elastic force. In order to ensure this sufficient length, as shown in FIG. 4, the wall thickness of the end portion of the movable casing case 101 connected to the spring portion 304 is thinner than the other portions. By doing so, it is possible to form the support plate 402 having a sufficient length.

  Further, in the vicinity of the base of the support plate portion 402, the surface opposite to the surface facing the inner wall surface 301 and the inner wall surface 302 is curved and connected to the movable housing case 101. Thereby, the elastic force is generated at the base of the support plate portion 402, and the strength is secured so that the base plate of the support plate portion 402 does not break even if the base is deformed.

  The curved portion 403 is curved and extends from one end of the support plate portion 402. The bending portion 403 is bent to generate an elastic force, and the camera 103 is pressed by the elastic force and the elastic force generated at the base of the support plate portion 402.

  The flat surface portion 404 extends in a planar shape from one end of the bending portion 403 toward the bottom surface 303 while being separated from the support plate portion 402. The flat surface portion 404 transmits the elastic force generated at the base of the support plate portion 402 and the bending portion 403 to the pressing portion 405. Further, the flat surface portion 404 is inclined so as to be separated from the support plate portion 402 as it approaches the bottom surface 303, thereby guiding the camera 103 to an appropriate position when the camera 103 is incorporated into the camera fixing portion 201.

  The pressing portion 405 extends perpendicularly from the one end of the flat portion 404 to the bottom surface 303. The pressing unit 405 presses the camera 103 by the elastic force transmitted from the plane unit 404 when the camera 103 is incorporated in the camera fixing unit 201. And the press part 405 makes the camera 103 contact | abut to the inner wall surface 301 and the inner wall surface 302, and fixes a position.

  In addition, since the pressing portion 405 extends perpendicularly to the bottom surface 303 in a state where the camera 103 is not incorporated, when the camera 103 is incorporated and pushed into the support plate portion 402 side, the inner wall surface 301 and the inner wall surface 302 are pushed. The surface that faces is directed toward the bottom surface 303. For this reason, the spring portion 304 has elasticity that expands and contracts in the direction toward the bottom surface 303 in addition to the inner wall surface 301 and the inner wall surface 302, and the elastic force transmitted to the pressing portion 405 causes the camera 103 to move to the bottom surface 303. It is also pressed in the direction. As a result, the camera 103 comes into contact with three surfaces of the inner wall surface 301, the inner wall surface 302, and the bottom surface 303, and the position is reliably fixed.

  FIG. 5 is a diagram illustrating a state in which the camera 103 is fixed to the camera fixing unit 201. As shown in FIG. 5, the camera 103 is pressed by the pressing portion 405 of the spring portion 304 and comes into contact with the three surfaces of the inner wall surface 301, the inner wall surface 302, and the bottom surface 303. At this time, the pressing portion 405 presses the camera 103 by the elastic force generated at the base of the support plate portion 402 and the bending portion 403.

  In the state where the elastic force is generated in this way, as shown in FIG. 5, the support plate portion 402 moves away from the inner wall surface 301 and the inner wall surface 302 as it goes from the root to one end connected to the bending portion 403. Tilt. Further, the bending portion 403 is bent with a small inner diameter as compared with a state where the camera 103 is not fixed. In this state, since the camera 103 is pressed toward the inner wall surface 301, the inner wall surface 302, and the bottom surface 303 by the elastic force, the position of the camera 103 is fixed.

  In addition, since the base of the support plate portion 402 and the curved portion 403 have elasticity, even a camera having a size different from that of the camera 103 can be fixed to the camera fixing portion 201. That is, since the difference in camera size is absorbed by the base of the support plate 402 and the elasticity of the curved portion 403, the camera fixing unit 201 can fix the positions of cameras having different sizes.

  Here, the size of the camera that can be fixed to the camera fixing unit 201 according to the present embodiment will be described. The camera fixing unit 201 presses the camera toward the inner wall surface 301, the inner wall surface 302, and the bottom surface 303 by the elastic force generated in the spring unit 304. Therefore, the fixable camera has a size at which an elastic force is generated at least in the spring portion 304.

  In order for an elastic force to be generated in the spring portion 304, the camera has a size enough to push the pressing portion 405 of the spring portion 304 toward the support plate portion 402 when the camera is fixed to the camera fixing portion 201. . That is, the length of the diagonal line of the surface parallel to the bottom surface 303 of the camera is larger than the length L1 from the angle at which the inner wall surface 301 and the inner wall surface 302 shown in FIG.

  On the other hand, if the size of the camera is excessively large, when the camera is fixed, the base of the support plate portion 402 and the bending portion 403 are greatly deformed, and the spring portion 304 may be damaged. For this reason, the length of the diagonal line of the plane parallel to the bottom surface 303 of the camera is preferably smaller than the length L2 from the angle at which the inner wall surface 301 and the inner wall surface 302 shown in FIG. .

  Further, as shown in FIG. 7, in a state where the camera 103 is fixed to the camera fixing portion 201, the pressing portion 405 is pushed into the support plate portion 402 side by the camera 103. At this time, a large pressing force is applied to the camera 103 in the normal direction of the surface of the pressing portion 405. In addition, since the normal direction includes a component toward the bottom surface 303, it is possible to prevent the camera 103 from being pressed toward the bottom surface 303 and the camera 103 to be lifted from the bottom surface 303.

  Therefore, when the camera 103 is fixed to the camera fixing unit 201, the camera fixing unit is used to fix the camera 103 having a size in which the angle α formed between the normal direction of the surface of the pressing unit 405 and the horizontal direction parallel to the bottom surface 303 is an appropriate size. It is preferable to fix to 201. Specifically, the camera 103 having a size with an angle α of approximately 30 to 60 degrees is preferable. In particular, the camera 103 is securely fixed to the camera fixing unit 201 when the angle α is approximately 45 degrees. . That is, by incorporating the camera 103 having a size within a range in which the angle α of the pressing force satisfies the above condition into the camera fixing unit 201, the camera 103 is appropriately pressed in the direction of the inner wall surface 301 and the inner wall surface 302. The pressure is also moderately pressed in the direction of the bottom surface 303.

  Next, a specific example of the method for forming the camera fixing unit 201 according to the present embodiment will be described.

  In the present embodiment, the spring portion 304 of the camera fixing portion 201 is integrally formed with the movable casing case 101. Therefore, when the movable casing case 101 is manufactured by molding a resin using a mold, a mold 801 that matches the inverted U-shape of the spring portion 304 is used, for example, as shown in FIG. It is done. Since the movable-side housing case 101 is provided with the spring portion 304, cameras of various sizes can be fixed to the camera fixing portion 201. Therefore, the mold for manufacturing the movable-side housing case 101 is one. Kind is good. For this reason, the manufacturing process of the some portable terminal device from which the specification and size of a camera differ can be made shared, and efficiency can be achieved.

  In FIG. 8A, when the mold 801 is removed, the mold 801 can be removed by sliding in the direction of the arrow shown in FIG. 8B, for example. By doing so, it is possible to prevent the pressing portion 405 from being caught by the mold 801 and being damaged when the mold 801 is removed.

  As described above, according to the present embodiment, a spring portion having elasticity is provided at one corner of the recess formed in the housing in which the camera is disposed, and the camera is pressed in the diagonal direction of the recess by the spring portion. It is made to contact | abut to the inner wall face and bottom face of a recessed part. For this reason, the difference in camera size can be absorbed by the elasticity of the spring portion, and cameras of various sizes can be fixed in the recesses. As a result, even if the specifications and sizes of the cameras are different, a common housing can be used, and the manufacturing process of the portable terminal device can be made more efficient.

  In the above embodiment, the spring portion 304 has the flat surface portion 404, but the shape of the spring portion is not limited to this. That is, for example, a spring portion 901 having a shape as shown in FIG. 9 can be provided. The spring portion 901 includes a support plate portion 902, a bending portion 903, and a pressing portion 904, and corresponds to the support plate portion 402, the bending portion 403, and the pressing portion 405 of the spring portion 304 described above, respectively. Thus, even in the spring portion 901 having no flat portion, the pressing portion 904 presses the camera by the elastic force generated at the base of the support plate portion 902 and the bending portion 903. Therefore, the camera can be brought into contact with the inner wall surface 301, the inner wall surface 302, and the bottom surface 303 to fix the position.

  In the above-described embodiment, the spring portion 304 is provided at the diagonal of the angle at which the inner wall surface 301 and the inner wall surface 302 intersect. However, a configuration may be adopted in which one spring portion is provided on each facing surface of the adjacent inner wall surface 301 and inner wall surface 302. In the case of this configuration, the camera is pressed in the direction of the inner wall surface 301 and the inner wall surface 302 by the spring portions provided on the respective faces.

  Furthermore, in the above-described embodiment, the spring portion 304 is formed integrally with the movable case body 101 made of resin. However, the spring part may be provided as an independent member. For example, a metal member may be fixed to the housing case and used as the spring part.

  In the above-described embodiment, the camera has been described as an example of a component incorporated in the mobile terminal device. However, various components other than the camera can be fixed using the spring portion. For example, it is possible to fix the position by pressing a liquid crystal panel, a substrate, or the like with an elastic force generated in a spring portion and bringing it into contact with a wall surface in the housing. Even in this case, by molding one type of casing, components of various sizes can be fixed in the casing, and the manufacturing process of the apparatus can be made more efficient by reducing costs.
