Title:
POWER-ASSISTED BACK-PUSH BEDSTEAD AND ELECTRIC BED
Document Type and Number:
WIPO Patent Application WO/2024/040715
Kind Code:
A1
Abstract:
A power-assisted back-push bedstead and an electric bed. The power-assisted back-push bedstead comprises a fixing frame (1), a backrest support (2) and a power-assisting support (4), wherein the power-assisting support (4) has a boosting arm (401) synchronously rotating with the power-assisting support (4), and a free end of the boosting arm (401) abuts against a back face of the backrest support (2) at least when the backrest support (2) is in a folded state. The power-assisted back-push bedstead further comprises a slider and an electric push rod (3), wherein the slider is linked to the power-assisting support (4), and when the slider slides, the power-assisting support (4) can be driven to rotate; the electric push rod (3) is connected to the backrest support (2) and the slider; when the slider is driven by the electric push rod (3) to slide from a first position to a second position, the backrest support (2) rotates to unfold from the folded state; and when the slider stays at the second position, the backrest support (2) can be driven by the electric push rod (3) to continue to rotate to unfold relative to the fixing frame (1), so as to adjust an inclination angle of the backrest support (2). The power-assisted back-push bedstead and the electric bed have a small package size, and the electric push rod (3) can rapidly unfold the backrest support (2) merely by means of a relatively small force in an initial state.
