All-directional ultrasound detecting movement mechanism

Abstract

The present invention provides an omni-directional ultrasonic detection motion mechanism and comprises a cabin and an overall mechanism arranged in the cabin. The cabin consists of an upper hatchcover and a lower hatchcover; the overall mechanism consists of a movement input mechanism, a movement transformation mechanism, a direction transform mechanism and an extending displacement increasing mechanism; the movement input mechanism comprises a DC electric machine and a crank block mechanism; the DC electric machine connects with the crank block mechanism; the crank block mechanism connects with the movement transformation mechanism; the direction transform mechanism connects with the movement transformation mechanism; the movement of the extending displacement increasing mechanism is inputted by the same DC electric machine, and the extending displacement increasing mechanism connects with an external connecting lateral plate through a transmission fork, then drives the external connecting lateral plate to movjinakanishe axially; the external connecting lateral plate connects with the lateral plate of an ultrasonic detector of an installation embarkation ultrasonic detector 10. The present invention realizes the space coupling movements of 2 degree of freedom using the single degree of freedom drive, and can realize the required omni-directional space detection of the ultrasonic detector by appropriately arranging the basic parameters such as the crank length, the connecting rod length and the mechanism bias, the teeth number of gear, and so on.

Description

(1) Technical field [0001] The invention relates to a movement mechanism, in particular to an omnidirectional ultrasonic detection movement mechanism. (2) Background technology [0002] With the development of science and technology, there is an urgent need for flexible mobile micro-robots in the fields of anti-terrorist reconnaissance and high-rise building detection. Ultrasonic probes are often mounted on tiny robots to detect obstacles and build maps. [0003] Most of the currently reported ultrasonic detectors mounted on microrobots adopt fixed and distributed installation forms. If the ultrasonic detectors in this form need to realize all-round detection, more detectors need to be distributed, and if the ultrasonic detectors When the detector is not working, it will still be exposed outside, and the dustproof and concealment properties are not good, so it is difficult to meet the requirements of practical applications. And the prior art all belongs to detection cloud ...

Problems solved by technology

[0003] Most of the currently reported ultrasonic detectors mounted on microrobots adopt fixed and distributed installation forms. If the ultrasonic detectors in this form need to realize all-round detection, more detectors need to be distributed, and if the ultrasonic detectors When the detector is not working, it will still be exposed, and the dustproof and concealment are not good, so it is difficult to meet the actual application requirements

However, the existing technologies all belong to the detection pan / tilt, the mechanism is relatively large in size, has no concealment, affects the appearance of buildings, and has a small scope of application.
