Patent ID: 8186222

Claim:
A centrifugal force sensing device, comprising: a first rotating shaft; two first movable sleeves, slidingly disposed on the first rotating shaft; a first weight; two first linkages respectively having a first end and a second end, wherein the first ends of the two first linkages are connected to the first weight, and the second ends of the two first linkages are respectively connected to the two first movable sleeves; a restoration element, comprising a fixing block and two first damping elements, wherein the fixing block is fixed at the first rotating shaft and located between the two first movable sleeves, and the two first damping elements are disposed at the first rotating shaft and respectively located between each of the two first movable sleeves and the fixing block; two first contact-based sensing elements, respectively disposed at the two first linkages and located between the two first linkages for generating first sensing information; a second weight; two second linkages respectively having a first end and a second end, wherein the first ends of the two second linkages are connected to the second weight, and the second ends of the two second linkages are respectively connected to the two first movable sleeves; two first fixing sleeves, fixed at the first rotating shaft and respectively located at the outer sides of the two first movable sleeves; and two fixers, fixed at the first rotating shaft and respectively located at the outer sides of the two first fixing sleeves.
