A motor, an active suspension, and a vehicle. The motor comprises a primary structure, at least one secondary structure, and at least one magnetic component. The secondary structure is spaced apart from the primary structure, and the secondary structure is configured as a plate-like structure. The magnetic component is connected to the secondary structure, and the magnetic component is located between the primary structure and the secondary structure.

A motor, an active suspension and a vehicle, the motor comprising a primary structure and a secondary structure. The primary structure comprises at least one fixing surface and coils. The fixing surface is provided with a plurality of first protruding portions, the first protruding portions protruding out of the fixing surface, and the plurality of first protruding portions being arranged at intervals in a first direction. The coils are arranged to surround the first protruding portions, the surrounding center line of each coil being perpendicular to the fixing surface, and the first direction being not parallel to the surrounding center line. The secondary structure is spaced apart from the primary structure, and the secondary structure is arranged opposite to the coils.

A vehicle is provided. The vehicle includes a seat. The seat includes a seat armrest and a seat armrest screen. The seat armrest screen includes a posture adjustment assembly for a display screen. The seat armrest includes an armrest body, the posture adjustment assembly, and the display screen. The armrest body has a screen mounting surface provided with a storage recess. The posture adjustment assembly is arranged on the armrest body. The display screen has a display surface and is mounted on the posture adjustment assembly. The posture adjustment assembly drives the display screen to flip between a storage position and an extension position. When the display screen is in the storage position, the display screen is accommodated in the storage recess, and the display surface is flush with the screen mounting surface. When the display screen is in the extension position, at least part of the display screen is located outside the storage recess, and an edge of the display surface adjacent to the screen mounting surface constitutes a flip edge that is flush with the screen mounting surface.

A muffler system and a vehicle are provided. The muffler system includes a first muffler and a gas purification apparatus, where the gas purification apparatus is disposed in the first muffler, the first muffler is provided with a first gas inlet and a first exhaust outlet, the first gas inlet is configured to receive waste gas generated by an engine, and the first exhaust outlet is configured to discharge the gas.

An electronic lock detection circuit is provided, including an electronic lock and a signal conversion circuit, where the electronic lock and the signal conversion circuit are located in a same detection circuit, and the signal conversion circuit is configured to convert a collected signal of the electronic lock and then send a converted signal to a processor.

An electronic expansion valve (1), a thermal management system, and a vehicle are provided. The electronic expansion valve (1) includes: a valve seat assembly (10), the valve seat assembly (10) being provided with a valve port (121); a valve needle assembly (20), the valve needle assembly (20) being disposed on the valve seat assembly (10) in a reciprocating manner to open or close the valve port (121); and an anti-rotation assembly, the anti-rotation assembly being disposed between the valve seat assembly (10) and the valve needle assembly (20), and the anti-rotation assembly being configured to limit rotation of a portion of the valve needle assembly (20) that at least cooperates with the valve port (121).
