The utility model discloses a lifting assisting mechanism for skylight glass, which belongs to the field of skylight glass and comprises the skylight glass arranged on a skylight frame. The power assisting component is arranged between the skylight glass and the skylight frame and comprises an upper swing arm and a lower swing arm, the close ends of the upper swing arm and the lower swing arm are hinged through a hinge joint, and the far ends of the upper swing arm and the lower swing arm are hinged to the skylight glass and the skylight frame at the corresponding ends through hinge pieces correspondingly. A first extension spring is arranged in the upper swing arm, through the arrangement of the power assisting component, when the skylight glass is lifted, the first extension spring, the second extension spring and the steel wire rope are matched to form transverse driving force, upward lifting force is conveyed to the skylight glass, the lifting power of the electric push rod is reduced through the arrangement of the power assisting component, the sound is smaller, and the service life of the skylight glass is prolonged. The power-assisted components on the two sides of the skylight glass are convenient to lift the skylight glass, and besides, the lateral rigidity effect is enhanced.

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 relates to a standpipe, a frame and a two-wheeled vehicle, which comprise a fixed seat, a connecting pipe and a joint which are connected in sequence, the fixed seat is used for installing a handlebar, and the joint is used for being connected with a front fork; the connecting pipe is sectioned in a first plane perpendicular to the extending direction of the connecting pipe to form a cross section, the size of the cross section in the first direction is smaller than the size of the cross section in the second direction perpendicular to the riding direction of the bicycle, and / or the wall thickness of the cross section in the first direction is smaller than the wall thickness of the cross section in the second direction. Such that a moment of inertia of the cross-section with respect to a first axis extending in the first direction is greater than a moment of inertia of the cross-section with respect to a second axis extending in the second direction; the second direction is perpendicular to the first direction. Compared with the mode that a round pipe is adopted in the prior art, the lateral rigidity of the vertical pipe is improved, and the use requirement is met.

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.
