The utility model relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle high-definition video transmission device, which comprises a vehicle body integrally designed in a cuboid shape; the telescopic wings are respectively arranged at four corners of the aircraft body; the high-definition camera is fixedly arranged at the lower end of the machine body through a multidirectional clamping mechanism, the multidirectional clamping mechanism comprises side wing clamping plates, the side wing clamping plates are symmetrically and movably arranged at the lower end of the machine body through a distance adjusting mechanism, every two side wing clamping plates are arranged in a rectangular mode, and sliding blocks are fixedly installed on the side walls of the side wing clamping plates; according to the device, a ratchet locking mechanism of the side wing clamping plate and the distance adjusting mechanism eliminates transverse displacement and prevents a camera from shaking, elastic lifting of the L-shaped clamping plate is matched with a damper of the damping mechanism, more than 85% of vertical impact energy is absorbed, it is ensured that images do not shake, the image quality of high-definition video transmission equipment is clear, and the service life of the high-definition video transmission equipment is prolonged. The utility model has the characteristics of strong practicability and fast adaptation capability.

The utility model discloses a kind of starry sky roller blind mechanism for car, comprising: main frame, fixed in sunroof roof interior, the main frame includes shell, slide rail and limit board;Roller blind cloth, roller blind cloth adopts three-layer composite structure, from inside to outside in turn is light-blocking base layer, buffer middle layer and light-transmitting surface layer;Optical fiber bundle, optical fiber bundle is in buffer middle layer in "S" shape path extension to avoid excessive stretch when winding up.Optical fiber bundle penetrates the three-layer structure of roller blind cloth, output end is flush with light-transmitting surface layer and is not outstanding, and the friction scratch when winding up is completely eliminated;Buffer middle layer in "S" shape path design, so that optical fiber can be along path slightly deformed when winding up stretch, avoid direct stress fracture, ensure that there is no extrusion when optical fiber winding, and optical fiber fracture rate is greatly reduced.

The utility model belongs to the field of automobile parts manufacturing technology, specifically, the utility model relates to a kind of reinforcing structure of automobile A column and B column;A kind of reinforcing structure of automobile A column and B column, including reinforcing shell, the reinforcing shell is arranged in A column and B column, reinforcing structure is arranged in the reinforcing shell;First reinforcing plate strengthens the intensity of A column and B column in longitudinal direction, effectively resist longitudinal tensile and compression force, prevent column body to occur longitudinal bending or fracture when colliding;Second reinforcing plate of interval distribution then strengthens horizontal rigidity, so that A column and B column can better keep structural integrity when being subjected to lateral impact, reduce lateral deformation. Both synergies, significantly improve the safety of A column and B column under complex collision working condition.
