Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent furniture and relates to an intelligent furniture mechanical extension structure. Background Art

[0002] Smart home provides consumers with a more convenient, comfortable and safe living environment and is loved by consumers. At present, the smart home market is developing rapidly. A sofa is a common piece of furniture. With the development of smart home technology, some sofas can now be connected to a smart home system to provide functions such as voice control.

[0003] With the development of society, people's needs are getting higher and higher. However, common sofas have a single function and mainly provide a tool for users to sit and lean on. In order to make people use the sofa more comfortably, an extension structure is provided on the sofa to meet people's different needs.

[0004] For example, a Chinese patent document with the publication number CN203633817U discloses a functional sofa with extensibility. The functional sofa includes a sofa seat. The sofa deformation support structure is that a bottom support plate is placed on the ground. A plurality of springs are fixed on the upper part of the bottom support plate. The upper ends of the springs are fixed with a support plate. A left inclined block and a right inclined block are fixed on the support plate. Return springs are fixed on the inclined surfaces of the left inclined block and the right inclined block. The upper ends of the return springs are fixed with a hinge plate. A first connecting rod is hinged on the hinge plate. The other end of the first connecting rod of the hinge plate at the left inclined block is hinged with an arc-shaped rod. The other end of the arc-shaped rod is hinged on a back fixing plate fixed on the back of the backrest part. The other end of the first connecting rod of the hinge plate at the right inclined block is hinged with a second connecting rod. The second connecting rod is hinged on an extension connecting plate fixed on the back of the extension part. This sofa realizes the contraction and extension of the inclined blocks through springs, which is prone to accidents. The deformation control is realized by magnetic attraction, and the control is unstable.

[0005] A patent document with the authorization publication number CN215737982U discloses a high-stability mechanical extension bracket and a sofa, including a sofa and an adjustment bracket. The adjustment bracket mechanism is composed of a guide rail, a limit hole, a slider, a spring, a locking pin and a connecting rod. The bottom of the sofa is fixedly connected with a guide rail. A plurality of limit holes are opened on both sides of the guide rail. When the tray needs to be unfolded, the locking pin is pressed into the slider, so that the spring is compressed. The slider is slid along the guide rail to the side of the tray, so that the connecting rod moves synchronously to support the tray. After reaching the appropriate position, the locking pin resets under the action of the spring elastic force and is inserted into the limit hole at the corresponding position. Through the cooperation of the locking pin and the limit hole, the positions of the slider and the tray are fixed, so that the connecting mechanism will not shake and shift, and the stability during the use of the tray is improved. However, during the use of this sofa, people need to press the slider by hand and then slide the slider, which is not conducive to use in a smart home. Summary of the Utility Model
