Title
(EN) Stopping block for inertial sensor
(ZH) 用于惯性传感器的阻挡块
Abstract
(EN)
The invention provides a stopping block for an inertial sensor. The stopping block is arranged on the surface of a substrate and used for blocking inertial movement of a mass block and comprises a body, wherein the position, in contact with the inertial mass block, of the body is a round corner, and the surface of the body and the surface of the substrate are made of the same material. The surfaceof the stopping block and the surface of the substrate are made of the same material so that the firmness degree of the stopping block can be increased by utilizing the characteristic of tight binding of homogeneous materials and the stopping block is not prone to shedding from the substrate. In addition, the position, in contact with the inertial mass block, of the body is the round corner so that the effective contact area between the stopping block and the mass block can be increased, and the possibility can be reduced that the stopping block is damaged after being bumped.

(ZH)
本发明提供了一种用于惯性传感器的阻挡块,设置在一基底表面,用于阻挡质量块的惯性移动,包括:本体,所述本体与所述惯性质量块接触的位置为圆角,且所述本体与所述基底表面为同一材料。本发明阻挡块与基底表面为同一材料,利用同质材料结合紧密的特点,可以增加阻挡块的牢固程度,不易从基底上脱落;并且将阻挡块与质量块接触的位置为圆角,可以增大阻挡块与质量块之间的有效接触面积,降低阻挡块被撞击后破损的可能性。
