This utility model discloses a device and vehicle for controlling the height and posture of a vehicle cab, comprising a height valve assembly and an adjusting linkage assembly. The height valve assembly includes a swing arm, a connecting shaft assembly, a rotor valve plate, a valve core assembly, an upper valve cover, and a lower valve body; the lower valve body has an air inlet, an air outlet, and an exhaust port with a muffler; the rotor valve plate and the valve core assembly cooperate to form a metal shear seal, switching the air path according to the swing arm position, and has a dead zone. The adjusting linkage assembly includes upper and lower connecting rods that can slide relative to each other and are locked by fastening sleeves, with connecting ball heads at both ends. This utility model has the advantages of large displacement, high inflation and deflation efficiency, fast response, good anti-fouling properties, low noise, and convenient adjustment, and is especially suitable for new energy vehicles, effectively improving the smoothness and reliability of the entire vehicle.

The application relates to a semiconductor detector, a CT scanning device and a detector position error measurement system. The semiconductor detector is applied to the CT scanning device and comprises a base structure, a protection layer and an engraved layer. The base structure comprises a semiconductor crystal layer and an electrode layer group, the electrode layer group comprises a planar electrode layer and a pixel electrode layer, the semiconductor crystal layer has a first surface and a second surface which are oppositely arranged along the thickness direction of the semiconductor crystal layer, the planar electrode layer is arranged on the first surface, and the pixel electrode layer comprises a plurality of pixel electrodes which are arranged on the second surface at intervals. The protection layer is arranged on at least part of the surface of the base structure. The engraved layer is formed on the side of the protection layer which is away from the base structure, and the engraved layer carries engraved information. The semiconductor detector can be engraved with marks on the surface without affecting the performance of the semiconductor detector, so that the crystal direction and other information of each semiconductor detector can be quickly identified during the installation process, and the installation efficiency is improved. After the installation is completed, the information of each semiconductor detector can be identified and traced according to the mark information.
