Description

New electric bed

technical field

The utility model relates to an electric bed technology, in particular to a novel detachable electric bed.

Background technique

It is well known that the electric bed can lift and lower the bed board through a driving structure. For example, a push rod motor is used as the power source, and the bed board is lifted and lowered by pushing the bed board with a push rod. However, in this type of driving structure, the motor of the push rod usually pushes the bed board to lift the bed board by extending the push rod. In order to keep the bed board in a raised state, the push rod of the push rod motor must always be in an extended state. And when the user leans on the bed, it will put pressure on the elongated push rod. According to the principle of material mechanics, the longer the length of the force-bearing rod, the easier the force-bearing rod is to bend and deform, and may even break in severe cases; In addition, such drive structures are difficult to install, maintain, and disassemble, which is time-consuming and labor-intensive for after-sales service personnel, and increases after-sales service costs for consumers.
