Cable reel

Abstract

The present invention relates to the field of robot application technology. The cable holder includes large roller, hand pushing handle, small roller, chassis, wheel shaft support, wheel shaft, small walking wheels, rocker, large roller walls and small roller wall. The large roller walls and small roller wall are fixed onto the wheel shaft separately, the large roller with the wheel shaft as shaft is fixed between two large roller walls, the small roller with the wheel shaft as shaft is fixed between the large roller wall and the small roller wall, the rocker is connected to the wheel shaft, the wheel shaft is supported on the chassis via its support, the small walking wheels are set below the chassis, and the hand pushing handle is set on the chassis. The present invention has no slip rings, and this results in less complexity, less weight, low cost and continuous signal transmission.

Description

technical field [0001] The invention relates to a cable reel, in particular to a cable reel for a mobile robot, belonging to the technical field of robot applications. Background technique [0002] Cable reels are widely used in electrical and mechanical fields, especially in the field of mobile robots. Although wireless remote control technology is relatively mature now, it has become the biggest bottleneck in the application of mobile robots due to its low reliability. Therefore, cable communication still occupies a very important position in the field of mobile robots. For cabled communication, the cable reel is an essential accessory. Common cable reels are plug and play, such as the cable reels produced by Yangzhou Huatai Cable Plate Factory (http: / / www.cable-plate.com), you must put the wires in place before plugging in the power plug (otherwise , with the rotation of the cable reel, there will be cable winding), which brings great inconvenience to practical applica...

AI Technical Summary

Problems solved by technology

Common cable reels are plug and play, such as the cable reels produced by Yangzhou Huatai Cable Plate Factory (http: / / www.cable-plate.com), you must put the wires in place before plugging in the power plug (otherwise , with the rotation of the cable reel, there will be cable winding), which brings great inconvenience to practical applications, and this kind of cable reel can only be used for power cables, and cannot transmit control, data, sound and other signals, so This kind of cable reel cannot be used in the field of mobile robots

Through literature search, it is found that American Remotec Corporation (URL http: / / www.remotec-andros.com ) A slip ring is added to the cable reel used in the risk-removing robot, which solves the problem of cable winding, and it can transmit data, voice and other signals, which greatly promotes the development of cable communication of mobile robots, but in the actual application process Among them, it also has many shortcomings: 1. The structure is relatively complicated, the cost is high, and the weight is heavy; 2. The slip ring transmits power or signals by contact, which is susceptible to interference and poor reliability, especially for image signals. Larger; 3. Using optical fiber communication, the quality is good and free from interference, but the optical fiber signal cannot pass through the slip ring, and the optical signal can only be converted into an electrical signal before the slip ring, which reduces the advantages of optical fiber
