A first reinforcement member 12 which has rigidity higher than the outer peripheral wall 3b is stored in the component storage recessed part 11. The first reinforcement member 12 is prevented from being removed from the component storage recessed part 11 by a double-sided tape 14 (a removal stopper structure).

Description

  The present invention relates to an electronic device having a casing that is partially insufficient in strength, and more particularly to a reinforcing structure thereof.

  Conventionally, for example, as disclosed in Patent Document 1, a housing formed by fitting a pair of cases and using a metal case formed of metal in one of the pair of cases forming the housing is used. There is known an electronic apparatus that has at least one reinforcing plate on a part of the inner surface of a metal case and forms a casing by fixing the other case to the reinforcing plate of the metal case.

JP 2004-7262 A

  However, in the above-described conventional electronic device, the reinforcing plate is directly attached to the inner surface of the metal case so as to ensure the rigidity. Therefore, the size of the reinforcing plate itself is increased, and thus a component such as a display unit provided on the inner side. Will become smaller.

  Although it is conceivable to insert-mold the reinforcing plate into the resin case, the shape of the reinforcing plate is limited due to restrictions on the shape of the mold, and it is not always possible to reinforce a portion having insufficient strength.

  This invention is made | formed in view of this point, The place made into the objective is to reinforce the housing | casing which lacks intensity | strength partially and simply.

  In order to achieve the above object, in the present invention, the reinforcing member is accommodated in a portion where the strength of the main cabinet is insufficient.

Specifically, in the present invention, a main cabinet constituting at least a part of the housing,
A component storage recess that has a recess in the rib that secures rigidity in the main cabinet;
A reinforcing member having rigidity higher than that of the rib housed in the component housing recess,
The reinforcing member is prevented from being detached from the component housing recess by a retaining structure.

  According to said structure, since rigidity can be ensured in the state which the reinforcement member was accommodated in the main cabinet and was prevented from coming off, the rigidity of the whole housing | casing improves. In addition, since a highly rigid reinforcing member can be housed in the component housing recess, it is not necessary to increase the thickness of the rib, and it is not necessary to reduce the components provided in the housing.

  As described above, according to the present invention, a reinforcing member having a rigidity higher than that of a rib is prevented from falling into a component storage recess in which a part of a rib for securing rigidity in a main cabinet constituting at least a part of a housing is recessed. By storing in such a state, it is possible to easily and inexpensively reinforce a housing partially lacking in strength.

(A) And (b) is a perspective view of a 1st reinforcement member. (A) And (b) is a perspective view of a 2nd reinforcement member. FIG. 6 is a view corresponding to FIG. 1 according to a first modification of the embodiment of the present invention. It is FIG. 1 equivalent view which concerns on the modification 2 of embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show a mobile phone 1 (smart phone) as an electronic apparatus according to an embodiment of the present invention. The mobile phone 1 includes a front cabinet 3 as a main cabinet in which a display unit 2 is accommodated, and a rear surface thereof. And a back side cabinet 4 covering the side. Further, the rear surface of the rear cabinet 4 is covered with a rear cover 5. For example, a rectangular plate-shaped rechargeable battery 6 and a circuit board 7 are accommodated in the accommodating space between the front side cabinet 3 and the back side cabinet 4. For example, the back side of the back side cabinet 4 is covered with a waterproof sheet 8. A coaxial cable 9 is arranged on the side of the circuit board 7 so as to extend vertically. The front cabinet 3, the back cabinet 4, and the rear cover 5 constitute a housing 10.

  As shown in FIG. 4, in the front side cabinet 3, a reinforcing frame 3a as a grounding component such as a stainless steel plate is insert-molded on the center side of an outer peripheral wall 3b made of a resin material. In the present embodiment, the outer peripheral wall 3 b constitutes a rib that ensures the rigidity of the front cabinet 3. The outer peripheral wall 3b is located on the left and right of the display unit 2, and the thickness (width) of the outer peripheral wall 3b needs to be reduced as much as possible with the recent enlargement of the display unit 2. Component storage recesses 11 are formed in the upper and lower intermediate portions of the left and right outer peripheral walls 3b. In the present embodiment, the component housing recess 11 is formed at a corner of the outer peripheral wall 3b with the reinforcing frame 3a. A waterproof packing 15 for sealing between the front side cabinet 3 and the back side cabinet 4 is provided on the back side of the component storage recess 11, and the component storage recess 11 and its surroundings are provided to maintain waterproofness. , Rigidity is needed.

  In each of the component storage recesses 11, the first reinforcing member 12 or the second reinforcing member 13 made of a bending structure such as a stainless steel plate having higher rigidity than the resin material constituting the outer peripheral wall 3b of the front cabinet 3 is stored. Has been. The first reinforcing member 12 on the right side as viewed from the front shown in FIGS. 1 and 6 has a trapezoidal cross section, for example, and the width W1 of the distal end surface 12a on the distal end side in the insertion direction is the same as that of the proximal end surface 12b on the proximal end side. It is smaller than the width W2 (W1 <W2). For this reason, it is easy to insert into the component storage recess 11. In addition, the press-fitting structure due to the fact that the width W1 of the first reinforcing member 12 on the distal end side in the insertion direction with respect to the component housing recess 11 is smaller than the width W2 on the opposite side of the insertion direction plays a role of retaining one. A double-sided tape 14 is affixed between the front end surface 12 a of the first reinforcing member 12 and the inner surface of the component housing recess 11. The adhesive structure using the double-sided tape 14 is also one of the retaining structures.

  On the other hand, in the left second reinforcing member 13 shown in FIGS. 5 and 7, the width W <b> 3 of the slit 13 a on the distal end side in the insertion direction is larger than the slit width of the first reinforcing member 12. Further, cable holding portions 13b for pressing the coaxial cable 9 by its elasticity are formed on the upper and lower ends, respectively. The coaxial cable 9 inserted in the inside and the 2nd reinforcement member 13 are electrically connected by the upper and lower cable clamping parts 13b. And since the width W3 of the slit 13a of the 2nd reinforcement member 13 is wide, when accommodating the 2nd reinforcement member 13 in the components storage recessed part 11, it inserts, making it elastically deform | transform in the direction which closes the slit 13a. As a result, the second reinforcing member 13 is pressed against the inner surface of the component housing recess 11, so that the coaxial cable 9 is reliably electrically connected to the reinforcing frame 3 a via the second reinforcing member 13. According to this configuration, it is possible to reliably prevent the generation of noise in the coaxial cable 9 while improving the rigidity of the housing 10.

  Furthermore, in this embodiment, the rechargeable battery 6 as a storage component is stored on the opposite side of the component storage recess 11, that is, on the left and right sides of the first reinforcement member 12 and the second reinforcement member 13. The first reinforcing member 12 and the second reinforcing member 13 are also prevented from coming off by the closed structure in which the open side of the component housing recess 11 is closed by the rechargeable battery 6.

  With such a simple configuration, the first reinforcing member 12 and the second reinforcing member 13 can be prevented from coming off.

  By configuring as described above, rigidity can be secured in a state where the first reinforcing member 12 and the second reinforcing member 13 are housed in the front-side cabinet 3 and are prevented from being detached, so that the rigidity of the entire casing 10 is improved. .

  Moreover, since the 1st reinforcement member 12 and the 2nd reinforcement member 13 can be accommodated in the components storage recessed part 11 without thickening the thickness of the outer peripheral wall 3b, components (especially rechargeable battery) provided in the housing | casing 10 can be accommodated. There is no need to reduce 6).

  Therefore, according to the mobile phone 1 according to the present embodiment, it is possible to easily and inexpensively reinforce the casing 10 that is partially insufficient in strength.

  In this modification, the 1st reinforcement member 12 and the 2nd reinforcement member 13 are comprised with the resin molded product. As shown only in the left second reinforcing member 13 in FIG. 8, a member-side engaging portion 13 c that engages with the housing-side engaging claw 11 a provided in the component housing recess 11 is provided on the distal end side in the insertion direction.

  In this modification, even when the first reinforcing member 12 and the second reinforcing member 13 cannot be inserted, or even when the resin material having high rigidity cannot be two-color molded, the rigidity of the housing 10 can be easily increased.

-Modification 2-
FIG. 9 shows a second modification of the embodiment of the present invention, which differs from the above embodiment in that the shape of the second reinforcing member 13 is different.

The arm 13d is grounded. Since the second reinforcing member 13 is also in contact with the reinforcing frame 3a, as a result, the circuit board 7 can be grounded to the reinforcing frame 3a. According to this configuration, since the second reinforcing member 13 can also be used as a grounding component, there is no need to separately provide a grounding component. The grounding arm 13d may be provided on the first reinforcing member 12 side, or may be provided on both.
