Abstract: A step, a step device and a vehicle are provided. The step includes a plurality of step segments, at least one connection step segment and a fastener, adjacent step segments include a first step segment and a second step segment, a first end of the connection step segment is slidably and detachably connected to the first step segment, a second end of the connection step segment is slidably and detachably connected to the second step segment, and the fastener is configured to fasten the connection step segment and the first step segment and to fasten the connection step segment and the second step segment.

Abstract: A step device is provided, including a step, a limiting assembly, and a driving assembly. The step includes a fixed board and a movable board. A first end of the movable board is rotatably coupled to a first end of the fixed board, so that a second end of the movable board has a first position and a second position. In the first position, the second end of the movable board is far away from the fixed board, and a top surface of the movable board is substantially flush with a top surface of the fixed board. In the second position, at least a part of the movable board overlaps with the fixed board in a thickness direction of the fixed board. The limiting assembly is used to limit the movable board in the first position or the second position. The driving assembly is coupled to the movable board to drive the movable board to rotate relative to the fixed board.

Abstract: A protective shell for a vehicle winch includes a first shell and a second shell. The first shell has a first end and a second end that are oppositely arranged in a first direction. The first end of the first shell is detachably connected to a rope guide of the vehicle winch. The first shell includes a through hole penetrating the first shell along the first direction and configured to accommodate at least a part of a buffer member of the vehicle winch. The second shell is detachably connected to the second end of the first shell to open and close the through hole.

Abstract: A step device includes: a mounting seat including a limiting part and configured to be mounted to a vehicle body; a step seat including an engaging part; a step mounted on the step seat; and an extension and retraction assembly connected to the mounting seat and the step seat, the extension and retraction assembly being configured to drive the step seat to move between an extended position where the engaging part is separated from the limiting part and a retracted position where the engaging part is engaged with the limiting part.

Abstract: A lighting device (100) for creating a living environment atmosphere, including an LED lighting source (102), a transparent housing (110) and an atmosphere optical film (112). The light-emitting angle of the LED lighting source is greater than or equal to 45 degrees, and the transparent housing is configured to clad the LED lighting source and has an atmosphere light filtering portion (104) and a lighting transparent bottom (106). The atmosphere optical film is located on a surface of the atmosphere light filtering portion and has a plurality of high refractive index layers (112b/112d/112f/112h/112j/112l/112n) and a plurality of low refractive index layers (112a/112c/112e/112g/112i/112k/112m/112o) arranged in a staggered manner.
