This utility model relates to the field of testing device technology and discloses a testing device for an automotive cockpit controller, comprising: a main cabinet, which is divided into multiple functional layers along a first direction by partitions, the functional layers being suitable for testing at least one function of the automotive cockpit controller; and a darkroom connected to the main cabinet, the darkroom being suitable for forming a dark space; the main cabinet includes: a first side panel, the first side panel being suitable for mounting the object under test for testing in the darkroom. By dividing the main cabinet into multiple functional layers along the first direction, the parallel testing capability of multiple functions of the automotive cockpit controller is realized. This not only optimizes space utilization but also significantly improves testing efficiency, allowing different functional modules to be tested simultaneously, greatly shortening the overall testing cycle. The connection design of the darkroom provides a controllable dark environment for optically related tests, ensuring the reliability and consistency of test data.

This utility model discloses a screw-driven lifting device, including a lifting drive mechanism, a housing, a screw support, a screw, a screw nut, a slider, and a guide rod. A bearing is embedded in the screw support; the outer ring of the bearing is fixed to the screw support, and the inner ring is fixedly connected to the screw, allowing the screw to rotate but preventing axial movement. The screw nut is fitted onto the screw and fixedly connected to the slider. The screw passes through two screw supports and the middle screw nut in sequence, with one end extending out of the housing. The lifting drive mechanism is fixedly installed at the exposed end of the screw. A guide rod passing through the slider guide hole is parallel to the side of the screw, used to guide and limit the slider, preventing rotation or swaying during lifting. The lifting drive mechanism drives the screw to rotate, causing the screw nut and slider to rise and fall smoothly along the screw axis. This device has a compact structure and high guiding accuracy, making it suitable for lifting applications in massage equipment and other devices requiring high space utilization and lifting accuracy.

This invention belongs to the field of full-face rock tunnel boring machine excavation technology, specifically providing a rectangular tunneling excavation device and tunnel boring machine, including a central cutterhead structure, a combined cutterhead structure, and a drive structure. The central cutterhead structure is a conventional full-face rock tunneling cutterhead structure, with an overall circular welded box-shaped structure. The combined cutterhead structure includes a first set of cutterheads and a second set of cutterheads symmetrically arranged along the center of the central cutterhead structure, and the first set of cutterheads, the central cutterhead, and the second set of cutterheads are interconnected to form a rectangular cutterhead structure. The drive structure is used to drive the central cutterhead structure and the combined cutterhead structure to rotate, thereby achieving excavation of the hard rock tunnel face. By setting separately driven central cutterhead structures and combined cutterhead structures, this invention allows for different cutterhead and drive combinations according to actual tunneling conditions; for example, in soft soil layers, cutterheads and drives suitable for soft soil layers can be installed.
