Description
Technical Field
The utility model relates to the technical field of furniture, concretely relates to automatic regulating apparatus of sofa.
Technical Field
The SOFA is a foreign vocabulary, which is transliterated by English "SOFA". The origin of the sofa dates back to the ancient Egypt era of 2000 at the earliest, and people at that time use wooden piles or stones to make tools for people to sit on, and later found that the sofa is a little more comfortable when people sit on the wooden piles or stones, and the sofa is a prototype. In the furniture appliance of the Pukraine Rui dug out by pompe in the famous historical city, a deck chair made of ivory and ebony has already been manufactured at a higher level. The early soft-packed sofas appeared at the end of the 16 th century and at the beginning of the 17 th century. The sofas of the time were primarily filled with natural elastic materials to provide a soft body-contacting surface. The material mainly comprises horsehair, bird feather, plant villi, etc., and natural goose down or other fabrics are used for covering the outside. It is not only more comfortable than hard seating, but also more gorgeous. The product is popular with people as soon as the product appears. Through the development of more than two thousand years, the change of the sofa is huge no matter the manufacturing material, the shape, the structure, the color and the precision, and the sofa is today compared with the sofa. Many new materials and new technologies show the body in the sofa manufacturing process, new varieties such as steel structure sofas, aluminum profile sofas, all-plastic sofas and inflatable sofas which are novel and unique appear, and the formation of the sofas is strengthened. Meanwhile, the shape of the sofa is continuously changed, and the sofa is more novel, elegant and beautiful and has strong time sense. In the aspect of structural design, the structure is more scientific and reasonable, and meanwhile, the structure is increasingly tightly combined with human engineering, so that the structure can better adapt to the requirements of human body shapes and physiological conditions. However, the existing sofa has some problems, such as the flexible adjustment is not available, and the sofa can bring people's enjoyment better.
The present adjustable sofa is mainly manually adjustable, such as chinese patent application No. cn201610517543.x, which discloses a telescopic frame for a seating unit, comprising a fixed bottom bar, a front support bar and a rear support bar rotating in a vertical plane, a cushion plate and a back plate arranged on top of the front support bar and the rear support bar and connected with each other, at least one ottoman couch, and an ottoman assembly extending and retracting the at least one ottoman. The manually adjusted sofa needs a person sitting on the sofa to use great force to pull the adjusting handle, which is inconvenient for some people with small strength, and the lifting of the front footrest is very unstable when adjusting the lifting of the front footrest, usually the front footrest is lifted steeply under the action of the force of the adjusting bracket, which may threaten our old users and has potential safety hazards; the user is required to press down the front plate with force by the legs when the front plate of the foot rest is put down, which is also inconvenient for part of the users.
Chinese patent with application number CN201510451426.3 discloses an electric sofa frame, including base support, bracket pushing mechanism, bracket mechanism, backrest mechanism and electric putter, bracket pushing mechanism connects bracket mechanism and backrest mechanism, and electric putter drives backrest mechanism.
