AI Technical Summary

⚠Technical Problem

In existing electric beds, the lower leg board tends to tilt when the thigh board is raised or lowered, causing the mattress to not fit properly against the lower leg board and posing a risk of slipping out.

⚗Method used

A lifting structure was designed. Through the cooperation of the first link and the second link, the driving component drives the first link to rotate, which in turn drives the second link and the lower leg plate to rise and fall synchronously, ensuring that the lower leg plate remains horizontal and avoiding tilting.

🎯Benefits of technology

It achieves synchronous lifting and lowering of the thigh and calf boards, preventing the calf board from tilting, ensuring that the mattress fits snugly against the calf board, reducing the risk of the mattress slipping out, and improving the user experience and stability of the electric bed.

Abstract

This utility model provides a lifting structure and an electric bed. The lifting structure includes a base frame, a thigh plate, a calf plate, and a lifting assembly. One end of the thigh plate is rotatably connected to the calf plate. The lifting assembly includes a drive component, a first connecting rod, and a second connecting rod. One end of the first connecting rod is rotatably connected to the base frame, and the other end is slidably connected to the calf plate. Both ends of the second connecting rod are rotatably connected to the first connecting rod and one end of the thigh plate, respectively. The drive component is activated to drive the first connecting rod to rotate, which in turn drives the second connecting rod to rotate. Simultaneously, the other end of the first connecting rod slides on the calf plate, so that one end of the calf plate and one end of the thigh plate move up and down synchronously. This application uses the drive component to drive the first connecting rod to rotate and slide on the calf plate, thereby driving the second connecting rod, so that the calf plate and the thigh plate move up and down synchronously. This ensures that the calf plate remains horizontal during the lifting process, preventing it from tilting and thus preventing the mattress from not fitting properly against the calf plate, reducing the risk of the mattress slipping out.
