Described connecting portion comprises shell, be arranged on servomotor in described shell, the reel with two winding slots by described driven by servomotor, be wrapped in rope yarn in described winding slot, be fixedly installed on two wire columns of described enclosure, described wire column end is provided with guide roller, described rope yarn one end is wrapped on described reel, the other end of described rope yarn is fixed on described body tip by described guide roller and body, and two rope yarns on described reel are around on the contrary.
Preferred technical scheme, is equipped with four wire guides on described cavity ring medial surface, described wire guide is arranged on described flexible connection point below.
Further technical scheme, described rope yarn is through wire guide described in each.
Preferred technical scheme, described servomotor is by reel described in gear reducer transmission, and described reel is coaxially connected with described gear reducer.
Preferred technical scheme, described shell is cylindrical.
In technique scheme, shell inward flange is also provided with two bullports, the guide roller of two wire columns is respectively over against two winding slots, and two rope yarns on winding slot are finally fixed in the cavity ring of extreme end through the wire guide in each cavity ring through each corresponding guide roller, bullport respectively again.
Principle of work of the present utility model, on individual module, be provided with body and two connecting portions, in connecting portion, be provided with servomotor and reel, servomotor drives reel rotation, due to two rope yarns on reel around on the contrary, when reel rotates, a rope yarn is strained another rope yarn and is loosened, and can make body draw deflection in to a side of rope yarn tension; And on individual module, be provided with two connecting portions, and in body, be altogether evenly equipped with 4 rope yarns, by servomotor, to the control of reel, can make the multi-aspect deflection of body twist.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, module of the present utility model itself can multi-aspect deflection, has increased the alerting ability of snakelike search and rescue robot, can in rugged environment, advance flexibly;
2, the utility model integral body is cylindrical, and the resistance being subject in when motion is less, is also not easy to be highlighted thing and catches on and cause advancing;
3, the utility model drives reel to rotate by servomotor, controls more accurately, by control, makes the deflection of body more flexible;
4, on wire column of the present utility model, use guide roller to lead to rope yarn, both reduced friction force and made rope yarn operation more smooth, can make again the whole structure of rope yarn folding and unfolding accurate.
