Title: ELECTRICALLY POWERED BED
Abstract:
Provided is an electrically powered bed, comprising: a base bed frame (1); a leg combination bed frame (2) articulated with the base bed frame (1) and able to pivot freely; a leg drive-mechanism support beam (3); a leg drive mechanism (4) comprising a first end part (41) and a second end part (42) for receiving driving force and enabling the leg drive mechanism (4) to pivot, said first and second end parts being articulated to the leg combination bed frame (2), and a pivot arm (43) arranged between the first end part (41) and the second end part (42) and articulated with the leg drive-mechanism support beam (3); and a leg drive motor (5), one end of which is articulated at the lateral frame edge near the leg drive-mechanism support beam (3) and the other end of which is articulated with the second end part (42) of the leg drive mechanism (4); when the leg drive motor (5) pushes the leg combination bed frame (2), it extends approximately along a straight line; therefore, one need only arrange an outer cover that is short in height in order to conceal the drive mechanism and the drive motor, making the outward appearance lighter, thinner, and more aesthetically pleasing.
