Abstract: A laterally diffused metal oxide semiconductor device and a preparation method thereof are disclosed. The semiconductor device includes: a substrate; a body region having a first conductivity type and formed in the substrate; a drift region, having a second conductivity type, formed in the substrate and adjacent to the body region; a field plate structure, formed on the drift region, a lower surface of an end of the field plate structure close to the body region being flush with the upper surface of the substrate, and the end of the field plate structure close to the body region also having an upwardly extending inclined surface; and a drain region, having a second conductivity type, formed in an upper layer of the drift region, and in contact with the end of the field plate structure away from the body region.

Abstract: A battery module and an electric vehicle are provided by the present application. The battery module includes a case body and at least one tray; at least one exhaust port is defined in the case body, at least one tray mounting cavity is defined in the case body, and the case body includes a first mounting surface surrounding a periphery of the tray; the tray is disposed in the tray mounting cavity to divide the tray mounting cavity into a cell accommodating cavity located above the tray and a pressure relief cavity located below the tray, the tray is provided with through holes facing battery cells, the pressure relief cavity is communicated with the through holes and the exhaust port, respectively, and the cell accommodating cavity is configured to accommodate the battery cells; the tray includes a second mounting surface, and the second mounting surface abuts against the first mounting surface.

Abstract: A bi-directional bypass lever assembly for activating an automotive liftgate lock mechanism includes a resetable spring-biased lever that is coupled to an automotive liftgate locking mechanism. The spring-biased lever resets itself automatically upon completion of both the locking mode and unlocking mode by the liftgate lock mechanism.

Abstract: An intermittent rotary motion mechanism for use in an automotive vehicle includes an electromagnetic device, a member moving in response to selective energization of the electromagnetic device, an intermittent motion mechanism and a window wiper shaft coupled to the intermittent motion mechanism. The intermittent motion mechanism moves the wiper shaft in a first wiping positional range when the electromagnetic device moves the member a first predetermined amount. The intermittent motion mechanism further moves the wiper shaft to a park position when the electromagnetic device moves the member a second predetermined amount in a first direction. The wiper shaft is mechanically deterred from movement from the park position concurrently with the electromagnetic device further moving the member past the second predetermined amount in the first direction.
