Frozen rain-preventing skylight mechanism

Abstract

The invention discloses a frozen rain-preventing skylight mechanism which comprises a head cover, a drive mechanism, a sliding mechanism, rainproof eaves and water retaining eaves, wherein the rainproof eaves are arranged at two sides of the lower end of the head cover and are of an V-shaped structure of an obtuse angle, flat edges are fixed on the head cover, and obtuse angle edges extend outside towards the outer side of the head cover to reduce rainwater splashing into the whole skylight mechanism like the eaves as much as possible and to reduce the frost quantity on a sliding rail as much as possible; the water retaining eaves are fixedly arranged at two sides of a skylight opening, so that (1) the rainproof function of the rainproof eaves is further strengthened and the rainwater is finally prevented from entering a cabin body through the skylight, and (2) ice water molten on the guide rail is prevented from entering the cabin body; a heating tape is also pasted on first C-shaped steel at the lower part of the guide rail of the sliding mechanism, ice on the guide rail is molten by heat generated through electrifying and heating, and artificial thawing is not needed; and the drive mechanism plays a role in automatically opening and closing the head cover and is especially suitable for the thawed skylight mechanism. The frozen rain-preventing skylight mechanism is reasonable in design, simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of shelters or van vehicles, and in particular relates to an anti-freezing and rain sunroof mechanism for shelters or van vehicles. Background technique [0002] Shelter or van vehicles are mostly used for engineering vehicles or communication vehicles, and most of them belong to the category of special vehicles. It is necessary to raise the measurement or testing equipment to the top of the vehicle. Therefore, the vehicle is required to have a skylight on the top for the entry and exit of equipment. The setting of the sunroof not only meets the basic work needs, but also plays the role of ventilation in the cabin. [0003] However, in severe cold and freezing environments, such as freezing rain and freezing, the driving mechanisms such as the guide rails of the sunroof will not be able to open due to freezing, affecting normal operations. And there is a safety hazard of slipping and falling. Contents of ...
