2results about How to "Large length" patented technology

A laser device includes a support, a first heat sink, a plurality of laser light sources attached to the support, and a plurality of electrodes bridged between the plurality of laser light sources and the first heat sink. Each of the plurality of laser light sources is movable with respect to the support. Each of the plurality of electrodes is electrically connected to one of the plurality of laser light sources at a first connection portion, and is thermally connected to the first heat sink at a second connection portion. In each of the plurality of electrodes, an extension part between the first connection portion and the second connection portion has flexibility, and a length of the extension part is larger than a linear distance between the first connection portion and the second connection portion.

The utility model discloses a variable mode walking mechanism for all terrain vehicle, including track body, drive wheel body, action support, mobile arm assembly and hydraulic cylinder, the track body is all rubber flexible track, drive wheel body is arranged in the track body and is in contact with the inner wall of track body, action support is arranged on drive wheel body, two mobile arm assembly symmetrical arrangement is on drive wheel body and is connected with action support, two hydraulic cylinders symmetrical arrangement is on drive wheel body, and hydraulic cylinder piston end is connected with mobile arm assembly, this variable mode walking mechanism for all terrain vehicle, simple and reasonable structure, clever design, to realize different track body ground contact length and ground contact area, ensure the high passability under the soft ground, the obstacle passing performance and the high mobility performance under the hard ground, the whole structure symmetry, the processing and manufacturing aspect, system stability is good.
