Title:
ULTRATHIN ELECTRIC BED HAVING WAIST PART EJECTION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/161160
Kind Code:
A1
Abstract:
An ultrathin electric bed having a waist part ejection function. A back part plate (11) and a waist part plate (12) are sequentially arranged on a front frame (21); the back part plate (11) is hinged to the waist part plate (12); the waist part plate (12) is fixedly connected to the front frame (21); and the front frame (21) drives the back part plate (11) to overturn relative to the front frame (21). A leg part plate (13) and a foot part plate (14) are sequentially arranged on a rear frame (22); the leg part plate (13) is hinged to the rear frame (22); the foot part plate (14) is fixedly connected to the rear frame (22); and the rear frame (22) drives the leg part plate (13) to overturn relative to the rear frame (22). The waist part plate (12) is provided with an opening (121) for allowing an ejection member (23) to pass therethrough; a fixed end of the ejection member (23) is hinged to the front frame (21); and a driver (24) can drive the ejection member (23) to pass through the opening (121) in a reciprocating manner. The opening (121) capable of accommodating the ejection member (23) is additionally arranged on the waist part plate (12), such that the ejection member (23) is sunk into the opening (121) in the waist part plate (12) when the driver (24) is not in operation, and it is guaranteed that the ejection member (23) does not protrude from the surface of the bed, thereby controlling the overall packaging height, improving the packing amount, reducing transportation costs, further being able to avoid a mattress being squeezed, prolonging the service life of a product, and being more aesthetically pleasing.
