Shield tail brush capable of monitoring morphological changes in real time

Abstract

The utility model relates to a shield tail brush of real -time monitoring morphological change, especially shield tail brush, its by bottom plate, lower bending plate, steel wire brush group, upper bending plate subassembly and apron are sequentially laminated and are composed, still include the stress sensing module and the signal transmission module who is used to receive and transmit stress sensing module signal in the shield tail brush main part of placing, the stress sensing module includes flexible stress piece, multi -axis stress piece array and elastic support plate, the flexible stress piece the multi -axis stress piece array place between the upper bending plate subassembly and the elastic support plate, the utility model discloses beneficial effect is: this technical scheme is through the lower surface of left inner protection plate and right inner protection plate and embeds flexible stress piece, when shield tail brush is subjected to the deformation of external force effect, flexible stress piece stretches along with, compresses or bends, and its internal conductive network or structure produces microscopic change, and then produces corresponding electric signal.
