ところで、前述したセンサ装置は、車両に加わる加速度の誤検出を防止するため、車両に固定した状態における共振周波数が所定周波数以上となるように設定されている。これは、基板固定部、基板弾性固定部及び筐体固定部の数及び配置によって実現されている。しかし、基板固定部が４箇所、基板弾性固定部が１箇所、筐体固定部が３箇所と固定部の数が非常に多い。そのため、部品点数や組付け工数が増加してしまうという問題があった。また、筐体を車両に固定する際に時間がかかり、作業性が悪いという問題もあった。   By the way, the sensor device described above is set so that the resonance frequency in a state of being fixed to the vehicle is equal to or higher than a predetermined frequency in order to prevent erroneous detection of acceleration applied to the vehicle. This is realized by the number and arrangement of the substrate fixing portion, the substrate elastic fixing portion, and the housing fixing portion. However, the number of fixing parts is very large, with four board fixing parts, one board elastic fixing part, and three housing fixing parts. Therefore, there has been a problem that the number of parts and assembly man-hours increase. In addition, there is a problem that it takes time to fix the housing to the vehicle and the workability is poor.

本発明は、このような事情に鑑みてなされたものであり、共振周波数を低下させることなく、固定部の数を低減することができる電子装置を提供することを目的とする。   This invention is made | formed in view of such a situation, and it aims at providing the electronic device which can reduce the number of fixing | fixed parts, without reducing a resonant frequency.

上記課題を解決するためになされた本発明は、加速度を検出する加速度センサと、加速度センサが固定される基板と、基板が収容され固定される筐体と、基板を筐体に固定する基板固定部と、筐体を対象物に固定する筐体固定部と、を備えた電子装置において、筐体固定部は、所定幅の直線状の領域内に直線方向に間隔をあけて２つ設けられ、基板固定部は、所定幅の直線状の領域内であって、２つの筐体固定部の間に直線方向に間隔をあけて２つ設けられていることを特徴とする。   The present invention made to solve the above problems includes an acceleration sensor that detects acceleration, a substrate on which the acceleration sensor is fixed, a housing in which the substrate is accommodated and fixed, and a substrate fixing that fixes the substrate to the housing. In the electronic apparatus including the housing portion and the housing fixing portion for fixing the housing to the object, two housing fixing portions are provided in a linear region having a predetermined width and spaced in a linear direction. The two substrate fixing parts are provided in a linear region having a predetermined width, and two board fixing parts are provided at intervals in the linear direction between the two housing fixing parts.

この構成によれば、筐体固定部と基板固定部が、概ね直線状に設けられている。そのため、共振周波数の低下を抑えることができる。しかも、筐体固定部と基板固定部が、それぞれ２つずつでよい。従って、共振周波数を低下させることなく、固定部の数を低減することができる。   According to this configuration, the housing fixing portion and the substrate fixing portion are provided in a substantially linear shape. Therefore, it is possible to suppress a decrease in resonance frequency. In addition, two housing fixing portions and two substrate fixing portions are sufficient. Therefore, the number of fixed parts can be reduced without reducing the resonance frequency.

Therefore, it is possible to suppress a decrease in resonance frequency. In addition, two housing fixing portions and two substrate fixing portions are sufficient. Therefore, the number of fixed parts can be reduced without reducing the resonance frequency.

第１実施形態によれば、加速度センサ１０２は、左右方向に伸びる幅Ｗの直線状の領域内であって、２つの基板固定部１６、１７の間に設けられている。そのため、共振に伴う加速度の誤検出を抑えることができる。   According to the first embodiment, the acceleration sensor 102 is provided between the two substrate fixing portions 16 and 17 in a linear region having a width W extending in the left-right direction. Therefore, erroneous detection of acceleration accompanying resonance can be suppressed.

第１実施形態によれば、加速度センサ１０２は、一方の基板固定部１７よりも他方の基板固定部１６に近い位置に設けられている。つまり、基板固定部のより近くに設けられている。そのため、共振に伴う加速度の誤検出をより抑えることができる。   According to the first embodiment, the acceleration sensor 102 is provided at a position closer to the other substrate fixing portion 16 than the one substrate fixing portion 17. That is, it is provided closer to the substrate fixing portion. For this reason, erroneous detection of acceleration accompanying resonance can be further suppressed.

第１実施形態によれば、左右方向に伸びる幅Ｗの直線状の領域は、基板１０の中央部を含む領域である。そのため、当該領域が基板１０の縁部に形成される場合に比べ、共振に伴う基板１０の変形を抑えることができる。   According to the first embodiment, the linear region having a width W extending in the left-right direction is a region including the central portion of the substrate 10. Therefore, the deformation of the substrate 10 due to resonance can be suppressed compared to the case where the region is formed at the edge of the substrate 10.

第１実施形態によれば、筐体１１に対する基板１０の固定方向と車両に対する筐体１１の固定方法が同一方向である。具体的には、上下方向である。そのため、共振に伴う変形を確実に抑えることができる。   According to the first embodiment, the fixing direction of the substrate 10 to the housing 11 and the fixing method of the housing 11 to the vehicle are the same direction. Specifically, the vertical direction. Therefore, it is possible to reliably suppress deformation associated with resonance.

なお、第１実施形態では、筐体固定部１４、１５及び基板固定部１６、１７が、左右方向に伸びる幅Ｗの直線状の領域内に形成される一直線上に設けられている例を挙げているが、これに限られるものではない。筐体固定部１４、１５及び基板固定部１６、１７は、当該領域内で前後方向にずれて設けられていてもよい。この場合、筐体固定部と基板固定部が、概ね直線状に設けられる。そのため、一直線状に設けた場合に比べ、共振周波数が多少低下するものの同様の効果を得ることができる。   In the first embodiment, the case fixing parts 14 and 15 and the board fixing parts 16 and 17 are provided on a straight line formed in a linear region having a width W extending in the left-right direction. However, it is not limited to this. The housing fixing parts 14 and 15 and the board fixing parts 16 and 17 may be provided so as to be shifted in the front-rear direction within the region. In this case, the housing fixing portion and the substrate fixing portion are provided in a substantially linear shape. Therefore, the same effect can be obtained although the resonance frequency is somewhat lowered as compared with the case where they are provided in a straight line.

また、第１実施形態では、１つの加速度センサ１０２が、２つの基板固定部１６、１７の間に実装され固定されている例を挙げているが、これに限られるものではない。複数の加速度センサが複数設けられていてもよい。所定幅の直線状の領域内であって、２つの基板固定部の間に実装され固定されていれば、同様の効果を得ることができる。   In the first embodiment, an example is described in which one acceleration sensor 102 is mounted and fixed between the two substrate fixing portions 16 and 17, but is not limited thereto. A plurality of acceleration sensors may be provided. The same effect can be obtained as long as it is mounted and fixed between two board fixing portions within a linear region having a predetermined width.

さらに、第１実施形態では、本発明に係る電子装置をエアバッグ制御装置に適用した例を挙げているが、これに限られるものではない。加速度センサと、基板と、筐体とを備えたものであればエアバッグ制御装置に限らず適用できる。   Further, in the first embodiment, an example in which the electronic apparatus according to the present invention is applied to an airbag control apparatus is described, but the present invention is not limited to this. Any device including an acceleration sensor, a substrate, and a housing can be used without being limited to the airbag control device.
