The application discloses a circuit board damping mechanism and a vehicle-mounted device adopting the same. The mechanism is used for fixing a circuit board with a through hole to a bottom plate. The damping mechanism comprises a packaging plate fixedly arranged on the bottom plate; a fixing bolt which comprises a nut and a stud, wherein the stud penetrates through the through hole and is matched with the nut to fix the circuit board on the packaging plate; and a damping gasket which is arranged between the circuit board and a nut of the fixing bolt. In the application, the bearing ring part of the damping rubber ring bears the main weight of the circuit board. When the equipment shakes longitudinally, the bearing ring part and the damping gasket at the upper part form an upper and lower buffer structure, and meanwhile, the circuit board is pressed under the action of the fixing bolt by utilizing the elasticity of the rubber ring, so that longitudinal impact on the circuit board is buffered while the circuit board is prevented from shaking up and down.
本申请公开一种路板减震机构及采用该机构的车载设备,该机构用于将具有通孔的电路板固定到底板,所述减震机构包括:集装板,所述集装板固设在所述底板上;固定螺栓,所述固定螺栓包括螺帽和螺柱,所述螺柱穿过所述通孔配合所述螺帽将所述电路板固定到所述集装板上;减震垫圈,所述减震垫圈设置在所述电路板与所述固定螺栓的螺帽之间。本申请中,减震胶圈的承载圈部承载起电路板的主要重量,在设备出现纵向晃动时,承载圈部与上部的减震垫圈构成上、下缓冲结构,同时利用胶圈本身的弹性在固定螺栓的作用下压紧电路板,避免电路板上下晃动的同时对电路板纵向的冲击进行缓冲。
