The present application relates to the technical field of laser countermeasure equipment, and provides a laser countermeasure launching device, which comprises a platform, a laser launcher arranged above the platform, a sighting scope fixed to one side of the platform, and a correction structure fixed to the top end of the platform. The correction structure is arranged to, when an electric push rod drives a moving plate on one side above the platform to move through a connecting plate, make the moving plates on both sides above the platform move reversely under the action of a hinged rod and a movable plate, enhance the stability of the moving plate when moving under the action of a sliding seat, make the moving plate after moving drive a clamping seat to move reversely through a supporting seat, make the clamping seat after moving clamp one side of the laser launcher, and make the laser launcher centrally fixed left and right. Under the action of the clamping seat, the laser launcher is centrally fixed up and down, and then the center line of the laser launcher and the center line of the sighting scope are collinear, thereby completing parallel calibration of the optical axis and the visual axis, and ensuring that the laser hits the target accurately when aiming.

The present application relates to a kind of flexible solar wing for sun synchronous orbit satellite constellation and on-orbit control method, solar wing is flexible stacked structure, stack on satellite body in retracted state, solar wing includes oppositely arranged single wing, the single wing includes: substrate assembly, it is configured to carry out photoelectric conversion, the substrate assembly includes: rigid substrate and several flexible substrates;Unfolding mechanism, it is configured to provide unfolding stiffness for solar wing, to ensure that the flexible substrate keeps planar form;And unfolding motor, it is configured to drive the unfolding mechanism unfolding or folding, to realize the retraction or unfolding of solar wing;First solar wing driving mechanism and lifting mechanism are provided between oppositely arranged single wing.The present application is overall used flexible stacked structure form retraction envelope size small, light in weight, does not need additional use satellite attitude control system to carry out attitude adjustment and realizes sun tracking.

The invention discloses an ear clamping type earphone and a wearing method, the ear clamping type earphone comprises a first convex part, a second convex part and a connecting arm, the first convex part is provided with a first contact surface in contact with the front surface of the auricle of a human body, and the second convex part is provided with a second contact surface in contact with the back surface of the auricle of the human body; when the earphone is clamped in the auricle of the human body, the direction of pressure acting on the front side of the auricle by the first contact surface is inclined to the deformation direction of the connecting arm, and the direction of pressure acting on the back side of the auricle by the second contact surface is inclined to the deformation direction of the connecting arm, so that torque opposite to the direction is generated on the earphone. During wearing, the first convex part is located in the auricle conchae cavity on the front face of the auricle, the second convex part is located on the back face of the auricle, and the connecting arm abuts against the helix; the ear clamping type earphone is stably worn on the auricle through three-position contact. According to the invention, an asymmetric and three-dimensional space torsion design is adopted, so that the whole earphone and the auricle form three contact areas, stable wearing is formed, a user can obtain stable hearing feeling, and the user experience is improved.
