The invention relates to a docking assembly mechanism for a large battery pack in a cabin. The docking assembly mechanism comprises a module grouping assembly, a battery pack placing trolley, an auxiliary adjusting assembly and a cabin docking assembly, the module grouping assembly is used for forming a battery pack by a plurality of battery modules; the battery pack placing trolley comprises a main beam frame, and a roller guide rail group, a baffle plate assembly and a walking assembly which are arranged on the main beam frame; the roller guide rail group is used for bearing and transferring battery packs; the baffle assembly is used for limiting the battery pack on the roller guide rail group; the auxiliary adjusting assembly is arranged between the roller guide rail set and the main beam frame, and the roller guide rail set evenly supports the battery pack by adjusting the height of the auxiliary adjusting assembly. The in-cabin butt joint assembly is arranged in the energy cabin; the butt joint guide rail group is used for being in butt joint with the roller guide rail group and guiding the battery pack into the energy cabin; and the butt-joint bolt hole seat is used for being matched with a bolt arranged on the battery pack to limit the battery pack on the butt-joint guide rail group. The device is reliable in structure and convenient to operate, and rapid and safe assembly of the large battery pack is achieved.

This utility model discloses a stator bearing assembly machine, which achieves full automation of the stator bearing assembly process through the coordinated layout of the pressing station, bearing feeding mechanism, pressing mechanism, and unloading mechanism. The compact frame integrates all functional units, resulting in a small footprint; automated assembly line operation eliminates manual handling, significantly improving single-piece assembly efficiency; precise connection between bearing feeding and pressing actions ensures high assembly position accuracy, eliminating the misalignment and damage associated with traditional manual assembly; the unloading mechanism automatically removes finished products, ensuring continuous production. The modular design of the overall structure reduces the risk of failure and lowers maintenance costs, making it particularly suitable for the stable mass production of small and medium-sized motor stators. Compared with traditional manual assembly, it effectively improves assembly efficiency and reduces production costs.

This utility model relates to the field of temperature, humidity, and VOC concentration detection technology, and discloses a detection device integrating temperature, humidity, and VOC concentration. It includes a bottom shell and a cover plate disposed inside the bottom shell. A circuit board is disposed inside the bottom shell. Positioning shells are fixedly connected to both sides of the bottom shell. An mounting component is disposed inside the positioning shell, and the mounting component includes a first toothed plate disposed inside the positioning shell. By providing mounting components containing a first toothed plate, a second toothed plate, a spring assembly, and a push rod on both sides of the bottom shell, and cooperating with the mounting plate on the side of the cover plate, the cover plate and the bottom shell can be quickly engaged and fixed. Disassembly and installation can be completed without tools, significantly improving the maintenance and repair efficiency of the detection device. The heat dissipation grooves in the bottom shell help dissipate heat from the circuit board, ensuring the stability of temperature, humidity, and VOC concentration detection. The design of the connecting groove in the cover plate, the positioning holes in the bottom shell, and the positioning pins further improves the assembly and positioning accuracy of the device.
