The invention relates to an extension mechanism of a service robot. The extension mechanism comprises a rack, a drawer guide rail, an air cylinder, a wire wheel, a steel wire, a reset mechanism and a wire wheel connector, wherein the drawer guide rail comprises a movable rail and a fixed rail; an accommodating cavity is formed in the rack; openings are formed in the front end and the rear end of the rack and communicate with the accommodating cavity; the fixed rail is installed in the accommodating cavity; the movable rail is in sliding connection with the fixed rail, and the front end of the movable rail extends out of the front opening of the rack; the air cylinder comprises a fixed part and a telescopic part, and the fixed part of the air cylinder is fixed on the rack; the wire wheel connector is fixedly connected with the telescopic part of the air cylinder, and the wire wheel is rotationally connected with the wire wheel connector; the steel wire is wound on the wire wheel, one end of the steel wire is connected with the fixed part of the air cylinder, and the other end of the steel wire is connected with the rear end of the movable rail; and the reset mechanism is installed at the rear end of the rack and connected with the rear end of the movable rail. According to the extension mechanism, the extension distance can be extended under the condition of single driving length, and the invention belongs to the technical field of robots.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to an extension mechanism of a service robot. Background technique [0002] With the rapid development of science and technology today, all kinds of robots emerge in endlessly. It is an unstoppable development trend to use artificial intelligence robots to replace humans to perform simple tasks, and service robots are one of the key industries for development, and service robots Object delivery by robots is an important function of service robots. A structure protruding forward is necessary for object transmission, but the current common structures such as rack and pinion drive and cylinder direct drive all have the problems of long drive source length, large space occupation, and complex reset structure. This problem also contradicts the trend of miniaturization and light weight of service robots in the future, so a structure protruding forward with extended moving distance is prop...
