Standing aid device

A standing aid device, comprising:

• a base assembly, a driving mechanism, and a linkage assembly;
• wherein
• the base assembly comprises a base and a pushing member, the pushing member is arranged above the base in a manner that the pushing member is capable of covering the base;
• the driving mechanism is arranged in the base, and a driving end of the driving mechanism is movable in a horizontal direction;
• the linkage assembly is arranged between the base and the pushing member, and comprises a guide member, a first push rod and a second push rod, wherein one end of the guide member is a connecting end and is hinged to the driving end of the driving mechanism, the driving mechanism pushes the guide member to move, causing another end of the guide member to swing upward, the first push rod has a first end and a second end, the first end is provided with a bent portion which is obliquely upward and extends away from a direction of the second end, the bent portion is hinged to the guide member, the second end is hinged to a bottom surface of the pushing member, the second push rod and the first push rod are arranged crosswise and are hinged at an intersection thereof, one end of the second push rod is slidably engaged with the pushing member, and another end of the second push rod is hinged to the base;
• when the driving mechanism is in a retracted state, the guide member is located at a first position, and said one end of the second push rod is located on top of the guide member and abuts against a top surface of the guide member;
• and
• when the driving mechanism is in an extended state, the guide member is located at a second position, and said one end of the second push rod is separated from the guide member.
