Description
近年、電子機器の薄型化および軽量化や携帯性の向上、電子機器内部の部品の破損防止のために、筐体に対して高剛性化が求められている。詳しくは、電子機器を片手で把持してもう一方の手で操作する時、電子機器の運搬時、モニタなどの開閉時に偏った荷重が付与されるため、筐体にねじり方向の力が作用する。また、運搬時に誤って電子機器を落下させてしまった場合にも同様にねじり方向の力が作用する。このため、筐体が高いねじり剛性（torsional rigidity）を有していることが求められている。また、筐体に対して満員電車などの窮屈な場所で圧力が付与されてしまう場合や物を落下させてしまった場合に（厚み方向に荷重が付与された場合）、内部の電子部品やディスプレイなどの液晶部品、特にガラス部材が破損する可能性があるので、筐体が高いたわみ剛性（deflection rigidity）を有していることが求められている。このような背景から、従来までに筐体の剛性を高める技術が数多く提案されている。 In recent years, high rigidity has been demanded for a housing in order to reduce the thickness and weight of an electronic device, improve portability, and prevent damage to components inside the electronic device. Specifically, when the electronic device is gripped with one hand and operated with the other hand, a biased load is applied when the electronic device is transported or when the monitor is opened or closed. . Similarly, if the electronic device is accidentally dropped during transportation, a force in the twisting direction is applied. For this reason, the housing is required to have high torsional rigidity. In addition, when pressure is applied to the housing in a tight place such as a crowded train, or when an object is dropped (when a load is applied in the thickness direction), internal electronic components and displays liquid crystal component of such, particularly there is a possibility that the glass member is damaged, it is required to casing has a high flexural rigidity (deflection rigidity). Against this background, many techniques for increasing the rigidity of the casing have been proposed.
図４および図５は、図２に示す補強部材３の構成の一例を示す断面図である。図４（ａ）に示すように、立ち壁部３２の周縁部からｘｙ平面に対して平行な外方方向に延伸するように接合部３３を設けてもよい。また、図４（ｂ）に示すように、立ち壁部３２の周縁部からｘｙ平面に対して平行な内方方向に延伸するように接合部３３を設けてもよい。また、図５（ａ），（ｂ）に示すように、底面カバー２の平面部２１（または補強部材３の接合部３３）に対する立ち壁部３２の角度αは、４５°以上、１３５°以下の範囲内にあることが望ましい。なお、図５（ａ）は立ち壁部３２の角度αが鋭角である状態を示し、図５（ｂ）は立ち壁部３２の角度αが鈍角である状態を示している。 4 and 5 are cross-sectional views showing an example of the configuration of the reinforcing member 3 shown in FIG. As shown in FIG. 4A, the joint portion 33 may be provided so as to extend from the peripheral portion of the standing wall portion 32 in the outward direction parallel to the xy plane. Further, as shown in FIG. 4B, the joint portion 33 may be provided so as to extend from the peripheral portion of the standing wall portion 32 in an inward direction parallel to the xy plane. Further, as shown in FIGS. 5A and 5B, the angle α of the standing wall portion 32 with respect to the flat portion 21 of the bottom cover 2 (or the joint portion 33 of the reinforcing member 3) is 45 ° or more and 135 ° or less. It is desirable to be within the range. 5A shows a state where the angle α of the standing wall portion 32 is an acute angle, and FIG. 5B shows a state where the angle α of the standing wall portion 32 is an obtuse angle.
