Vibration apparatus of electric bed

Abstract

A vibration apparatus of an electric bed includes a bed board having a hollow portion, and a base mount having a main body disposed with the bed board, a through hole communicated with the hollow portion, and at least three suspension arms extending from the main body to the through hole. Each suspension arm has a first end connected with the main body and a second end located in the through hole. At least three supporting members each have a base portion disposed with the main body or the first end of one suspension arm, and an extension portion abutting the second end of another suspension arm. A vibrator is located in the hollow portion and connected with the second ends of the suspension arms. The vibration apparatus of the electric bed is not only structurally stable and durable but also capable of delivering an appropriate vibration force.
