Abstract: Disclosed are a linear actuator control circuit capable of achieving accurate positioning, and a linear actuator. The control circuit comprises a motor driving circuit, a master control circuit and at least one intermediate switch; by disposing the intermediate switch between two ends of a stroke of the linear actuator, the intermediate switch can be triggered when the linear actuator runs to the intermediate switch; after the master control circuit receives information of the intermediate switch, running of the linear actuator is stopped, so that the linear actuator stops running when accurately running to a state that the intermediate switch is triggered, and then, accurate positioning of a sliding block on the linear actuator is achieved.

Abstract: The present disclosure provides a multifunctional cup holder for installation on a sofa and a sofa thereof. The cup holder includes: a base configured to attach to a sofa; a cup body; a flange disposed at an upper end of the cup body; and a control assembly disposed on the flange. A lower end of the cup body is attached to the base. The flange is detachable from the upper end of the cup body, and the flange extends radially inward towards a center of the cup body. The control assembly is removable from the flange and is configured to control operations of the multifunctional cup holder or adjustments of the sofa.

Abstract: The present invention discloses a sofa and a sofa switch, the sofa comprises a sofa body and one or more switches, wherein the sofa body is provided with one or more switch mounting holes, the switch comprises a columnar body and a pressing structure, an internal of the columnar body is provided with a mounting chamber penetrating upwards and downwards, the columnar body is mounted in the mounting holes; an upper end of the columnar body extends outwardly to form an extension part, the extension part fits with the sofa body; the pressing structure comprises a pressing part and a key cap, and the key cap covers above the extension part. The switch has the advantages of simple structure, flexible layout on the sofa, easy replacement and high reliability.

Abstract: The present invention discloses a storage bed with a horizontally lifted bed board, comprising a bed body provided with a storage cavity, a bed board frame covering the bed body, parallelogram lifting mechanisms symmetrically arranged on two sides of the bed board frame, and driving devices, wherein the parallelogram lifting mechanisms are connected to inner side walls of the storage cavity and the bed board frame, and the driving devices drive the parallelogram lifting mechanisms to push the bed board frame to be horizontally lifted towards a footboard direction of the bed body. The parallelogram lifting mechanisms are utilized to push the bed board frame to be horizontally lifted towards the footboard direction of the bed body, so that the bed board frame is prevented from coming into collision against a headboard in a lifting process; it is unnecessary to take down bedclothes when articles are stored or taken.
