Description

Technical Field

[0001] This utility model relates to the field of truck wind resistance technology, and in particular to a device for reducing truck wind resistance. Background Technology

[0002] Trucks, also known as freight vehicles or cargo trucks, are automobiles primarily used for transporting goods, and sometimes also refer to vehicles that can tow other vehicles. They belong to the category of commercial vehicles. This includes dump trucks, tractor-trailers, off-road trucks for off-highway and roadless areas, and various vehicles manufactured specifically for special needs.

[0003] The wind resistance of trucks mainly comes from the following aspects: First, the large frontal area and high chassis of trucks make air resistance a major issue. Second, the boxy rear cargo box design also increases air resistance. Increased wind resistance in trucks leads to increased load, resulting in higher fuel consumption, lower fuel efficiency, and higher operating costs. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for reducing wind resistance in trucks includes a truck body, the truck body including a cab and a cargo box, an upper airflow guide assembly is provided on the top of the cab, a side airflow guide assembly is provided between the cab and the cargo box, and a skirt airflow guide assembly is provided at the bottom of the outer wall of the cargo box.

[0007] Preferably, the upper airflow guide assembly includes an upper airflow guide plate disposed on the top of the vehicle front, a long shaft welded to the bottom outer wall of the upper airflow guide plate, symmetrically distributed fixed seats rotatably connected to the outer wall of the long shaft, and a spring fixedly connected between the fixed seats and the upper airflow guide plate.

[0008] Preferably, the side guide assembly includes a symmetrically distributed connecting frame fixed between the front of the vehicle and the carriage by screws, a side guide plate welded to the outer wall of one end of the connecting frame, and a side guide shroud hinged to the outer walls of both sides of the side guide plate.

[0009] Preferably, the skirt guide assembly includes a skirt guide plate fixedly connected to the bottom of both sides of the carriage by screws, and an arc-shaped guide plate disposed on the outer wall of one end of the skirt guide plate.

[0010] Preferably, symmetrically distributed connecting shafts are welded to the outer wall of the long shaft, and a short shaft is welded to the outer wall of one end of each of the two connecting shafts. The short shaft is fixedly connected to the bottom outer wall of the upper guide plate.

[0011] Preferably, a rubber compensation plate is adhered to one outer wall of the upper guide plate.

[0012] Preferably, the outer wall of one side of the side guide plate is provided with equally spaced diversion strips, and the inner wall of the side guide shroud is welded with symmetrically distributed reinforcing blocks.

[0013] Preferably, the outer wall of one side of the skirt guide plate is provided with symmetrically distributed flow dividers.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The device designed to reduce truck wind resistance is an upper airflow deflector installed on the truck cab. It is equipped with a self-adjusting upper airflow deflector. The elasticity of the spring can control the rubber compensation plate at one end of the upper airflow deflector to always be in contact with the surface of the truck cab, which is in line with aerodynamics and helps to reduce truck wind resistance and reduce the load on the truck when it is running.

[0016] 2.

[0017] 3. The device designed to reduce wind resistance in trucks features side skirts at the bottom of both sides of the truck bed. These skirts guide the airflow around the truck, changing its direction and further reducing wind resistance, improving fuel efficiency, and lowering operating costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1, refer to Figure 1-2 A device for reducing wind resistance of a truck includes a truck body 1, the truck body 1 includes a cab 2 and a cargo box 3, and an upper air guide component 4 is provided on the top of the cab 2, a side air guide component 5 is provided between the cab 2 and the cargo box 3, and a skirt air guide component 6 is provided at the bottom of the outer wall of the cargo box 3.

[0027] In this embodiment, an upper airflow deflector 4 is installed on the truck front 2, equipped with a self-adjusting upper airflow deflector 7. The elasticity of the spring 10 can control the rubber compensation plate 18 at one end of the upper airflow deflector 7 to always be in contact with the surface of the truck front 2, which is in line with aerodynamics and helps to reduce the truck's wind resistance and reduce the load when the truck is driving.

[0028] Example 2, refer to Figure 3-4 A device for reducing wind resistance in trucks, the side guide assembly 5 includes a symmetrically distributed connecting frame 13 fixedly connected between the front of the truck 2 and the truck body 3 by screws, a side guide plate 11 welded to the outer wall of one end of the connecting frame 13, and a side guide shroud 12 hinged to the outer walls of both sides of the side guide plate 11.

[0029] In this embodiment, under the action of the side guide assembly 5, the combination of the side guide plate 11 and the side guide cover 12 shortens the distance between the front of the truck 2 and the truck body 3, thereby further reducing the wind resistance between the two and further saving the truck's fuel consumption.

[0030] Example 3, refer to Figure 5A device for reducing wind resistance in trucks, the side skirt guide assembly 6 includes a side skirt guide plate 14 fixedly connected to the bottom of both sides of the truck body 3 by screws, and an arc-shaped guide plate 15 disposed on the outer wall of one end of the side skirt guide plate 14.

[0031] In this embodiment, skirt guide components 6 are provided on both sides of the bottom of the truck body 3, which guides the air around the truck, changes the direction of airflow, and can further reduce wind resistance, improve fuel efficiency, and reduce operating costs.

[0032] Reference Figure 2 Symmetrically distributed connecting shafts 16 are welded to the outer wall of the long shaft 8, and a short shaft 17 is welded to the outer wall of one end of each of the two connecting shafts 16. The short shaft 17 is fixedly connected to the bottom outer wall of the upper guide plate 7.

[0033] Reference Figure 2 A rubber compensation plate 18 is bonded to one side of the outer wall of the upper guide plate 7.

[0034] Reference Figure 3-4 The side guide plate 11 has equidistantly distributed diversion strips 19 on one outer wall, and the side guide cover 12 has symmetrically distributed reinforcing blocks 20 welded to its inner wall.

[0035] Reference Figure 5 The outer wall of one side of the skirt guide plate 14 is provided with symmetrically distributed diversion strips 21.

[0036] Working principle: Three sets of airflow guiding structures are distributed on the truck body 1, namely the upper airflow guiding assembly 4, the side airflow guiding assembly 5, and the skirt airflow guiding assembly 6. Among them, the elasticity of the spring 10 is used to keep the rubber compensation plate 18 at one end of the upper airflow guiding plate 7 in contact with the surface of the truck head 2, thereby reducing the truck's wind resistance. On this basis, the combination of the side airflow guiding plate 11 and the side airflow deflector 12 shortens the distance between the truck head 2 and the truck body 3, further reducing the truck's wind resistance. In addition, the skirt airflow guiding plate 14 and the arc-shaped airflow guiding plate 15 can guide the air around the truck and change the direction of airflow, thereby further reducing the truck's wind resistance.
