A rotary drive for functional furniture

Abstract

The invention discloses a rotary driver for functional furniture, which comprises a casing, the casing is installed on a body frame through a mounting mechanism, a driving mechanism is arranged in the casing, and the output shaft of the driving mechanism is coaxially connected There is a first-stage worm, the first-stage worm meshes with a first-stage worm gear located in the casing, the first-stage worm gear is coaxially connected with a second-stage worm, and the second-stage worm is rotationally connected with the casing , the second-stage worm meshes with a second-stage worm gear, and the second-stage worm gear is coaxially connected with an output square tube shaft extending from the casing, and the output square tube shaft is connected with a transmission plate, and the transmission plate is far away from The end of the output square tube shaft is provided with a pillow frame. The invention has the effect of reducing the pinching of the user by the rotary driver.

Description

technical field [0001] The invention relates to the technical field of rotary drives, in particular to a rotary drive for functional furniture. Background technique [0002] With the development of society, people's pursuit of quality of life is constantly improving. For the choice of furniture, consumers are not limited to a single function, but more hope to maximize the utilization rate of furniture, which is modern thinking. For example, seats or sofas, in addition to the pursuit of comfort, consumers also need seats that can realize various functions such as angle adjustment when used in different scenarios. [0003] Publication number is that the Chinese patent of CN106037340A discloses a kind of electric function sofa headrest mechanism, comprises headrest assembly, backrest assembly, electric push rod. The electric sofa headrest mechanism only needs the electric push rod to drive the headrest assembly and the backrest assembly to operate. When the switching power is...

AI Technical Summary

Problems solved by technology

Although this electric functional sofa headrest mechanism relies on the headrest assembly to realize multi-angle stable adjustment of the headrest mechanism under the drive of the electric push rod, so that consumers can control and adjust according to the angle they want, but in actual use , because the headrest mechanism will move, the lying part will often be separated from the headrest mechanism, thereby forming a gap. When the headrest mechanism performs ups and downs, the gap will become larger and smaller. into the gap, it is easy to cause pinching, this problem needs to be solved urgently
