Damping hinge structure and computer device

ActiveCN224453375UAvoid the risk of water leakageReduce the risk of injury from external forcesDisplay deviceStructural engineering
This utility model relates to a damping hinge structure and computer equipment, including a monitor front cover, a damping hinge, and a monitor rear cover. The monitor front cover is assembled with the monitor and detachably connected to the monitor rear cover. The damping hinge includes a central shaft and two cable guide slots. The central shaft is assembled with the monitor front cover, and the two cable guide slots are located at both ends of the central shaft. Each cable guide slot includes a nut mounting slot and a semi-open cylinder for assembling cables. Threaded connecting rods are provided at both ends of the central shaft, passing through the nut mounting slots and connecting to damping adjustment nuts. The cable guide slots are fixedly connected to the monitor bracket, and their semi-open cylinders have cable passage openings. This application, while allowing adjustment of the monitor angle, also enables cable routing within the device and allows the use of thicker cables without increasing the size of the monitor hinge connection. Furthermore, this application improves assembly manufacturability and after-sales maintainability, reducing manufacturing and after-sales costs.

Projection lens

The invention belongs to the technical field of projection optical lenses, and discloses a projection lens which can form a lens structure with a long back focal length through three lens groups which are respectively used for focusing, zooming and fixing, can obtain higher brightness and contrast through the lens structure with the long back focal length, and is more beneficial to heat dissipation. On the basis, continuous zooming can be achieved through the first zoom lens set, the second zoom lens set and the third zoom lens set which independently move along the optical axis, and meanwhile under the condition that the back focal length is long or the length of the lens is fixed, through the design in the aspects of back focal length control, lens materials and / or lens gluing and the like, continuous zooming can be achieved. The problems of chromatic aberration and difficult light correction caused by a long back focal length lens structure can be solved in the aspects of aberration, chromatic aberration and the like, the contrast ratio and the brightness are better improved, and the purposes of long back focal length, high brightness, low chromatic aberration, low distortion, large aperture and high imaging quality of the projection lens are finally achieved.

A novel design method for cooperative target pose observer based on potential functions

ActiveCN117029822BIt is estimated that the effect is goodbig choiceNavigational calculation instrumentsDesign optimisation/simulationEstimation methodsObserver based
This invention discloses a design method for a cooperative target pose observer based on a novel potential function, used for real-time position and attitude estimation of cooperative targets in space. Common pose estimation methods typically include static and dynamic methods. Dynamic methods combine observation information with the system's kinematic or dynamic information, and under the same conditions, usually yield better estimation results than static methods. As a dynamic estimation method, the observer is valued for its simple structure and ease of application. Addressing the problem of the limited variety of potential functions commonly used in current pose estimation observers, this invention, based on existing potential functions, proposes a method for constructing an observer based on a novel potential function. This method can be used for synchronous relative pose estimation during operations by a space robotic arm on a cooperative target. The observer derived from the novel potential function designed in this invention not only possesses the same theoretical stability characteristics as existing observers but also demonstrates better estimation performance in practical applications.
