Automatically-adjustable dome for truck

Abstract

The invention discloses an automatically-adjustable dome for a truck, which belongs to the technical field of automobile parts. According to the automatically-adjustable dome for the truck, two self-locking structures are fixedly connected to the upper portion of the dome, and two push rod support seat structures are fixedly connected to the top of a cab and movably connected with the slide way cavities of the two self-locking structures respectively; the upper portion of the dome is movably connected with the front end of the top of the cab; the lower portions of two domes are fixedly connected with the both ends of the top of the cab respectively; an electric control device comprises a circuit board located in the interior, as well as a gear-type adjustor, an automatic control switch and a power supply switch which are located in the exterior, and a vehicle power supply is used for supplying power; a sensor and two electric push rods are connected with the electric control device. The automatically-adjustable dome for the truck disclosed by the invention is simple in structure, convenient to operate, safe and reliable, and capable of automatically adjusting the height thereof rapidly and conveniently according to the different heights of the containers carried in the truck or different working conditions such as no-load, thus realizing a good drag reduction effect and saving fuel oil; the height of the dome can also be randomly controlled in a part of occasions, thus improving the adaptability of the device; corrective designs can also be performed aiming at different truck types, thus achieving a wide adaptation range of the truck types.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a height-adjustable wind deflector for trucks (cargo trucks, especially container trucks). Background technique [0002] When the truck is running, part of the power generated by the fuel is used to overcome the air resistance and do work; the air resistance is proportional to the square of the truck speed. For container trucks that are usually running at high speed, the effect of the shroud directly affects the fuel consumption of the truck and economic benefits. Existing container truck deflectors are generally used in a fixed position after installation, and generally only have a good drag reduction effect for containers of one height. However, due to different actual needs, the height of the container loaded on the truck will change or the truck is empty. For these cases, the drag reduction effect of the existing shroud will be greatly reduced. [0003] Altho...

Problems solved by technology

[0004] In order to overcome the inconvenience of adjusting the existing wind deflector and the lack of drag reduction and energy saving effects, the present invention proposes a wind deflector, which can be automatically controlled by the driver or the control module according to the height of the container to realize its own The electric adjustment can achieve better flow diversion and drag reduction effects for different heights of containers on the truck or different working conditions such as empty load
