Description

Technical Field

[0001] The invention relates to the technical field of air deflector covers, and in particular to a lightweight air deflector device for a truck cab. Background Art

[0002] When a truck is driving, air resistance is proportional to the square of the truck speed. For container trucks that usually travel at high speeds, the effect of the deflector directly affects the truck's fuel consumption and economic benefits. Existing deflectors for container trucks 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 carried by the truck may change or the truck may be empty. In these cases, the drag reduction effect of the existing deflector will be greatly reduced.

[0003] In order to solve the above situation, an adjustable deflector is currently used, and the inclination angle of the deflector can be adjusted according to the height of the container. However, the size of the adjustable deflector is currently fixed and cannot be adjusted according to the width of the truck cab, and has poor adaptability. Summary of the invention

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] like Figure 1-3As shown, this embodiment proposes a lightweight deflector device for a truck cab, and the deflector includes:

[0022] The arc-shaped main body cover 1 has a front end that is rotatably mounted on the middle of the top of the truck cab, and a rear bracket 2 that is mounted inside the rear end;

[0023] The rear bracket 2 and the fairing are flexibly connected, and the rigidity of the tail of the arc-shaped main body cover 1 is strengthened to reduce the probability of cracking caused by wind resistance.

[0024] The wing cover 3 includes two wing covers 3, which are respectively installed on both sides of the arc-shaped main body cover 1. The shape of the wing cover 3 matches the shape of the side of the arc-shaped main body cover 1, and the wing cover 3 is telescopically connected to the arc-shaped main body cover 1.

[0025] Furthermore, it also includes fastening bolts 10, and the two sides of the arc-shaped main body cover 1 are set as a double-layer structure with a cavity inside, and the fender cover 3 extends into the cavity to be telescopic, and the fastening bolts 10 are pressed against the fender cover 3 through the threaded through holes on the arc-shaped main body cover 1. The telescopic length of the fender cover 3 can be adjusted according to the width of the truck cab, and the application range is wide.

[0026] In this way, by telescopically connecting the wing cover 3 to both sides of the arc-shaped main body cover 1, the width of the air deflector can be adjusted according to the width of the truck cab, and the application range is wide.

[0027] Furthermore, if the inclination angle of the arc-shaped main body cover 1 is large, and the rear end of the arc-shaped main body cover 1 is not extended long enough, there will be a gap at the rear, which will weaken the effect of reducing wind resistance. In order to solve this problem, the air guide device in this embodiment also includes a rear cover 4, which is telescopically connected to the rear end of the arc-shaped main body cover 1, and the shape of the rear cover 4 matches the shape of the rear part of the arc-shaped main body cover 1. In this way, the telescopic length of the rear cover 4 can be adjusted according to the inclination angle of the arc-shaped main body cover 1.

[0028] It should be noted that the telescopic length fastening mechanism of the rear cover 4 and the telescopic length fastening mechanism of the fender cover 3 have the same structure, both of which are adjusted by fastening bolts. Of course, other structures can also be used. You can refer to the existing structure and determine it according to actual conditions. This article will not repeat them.

[0029] In this embodiment, an adjustment mechanism is provided between the rear support 2 and the top of the truck cab, and the adjustment structure is used to adjust the inclination angle of the arc-shaped main body cover 1 toward the rear end.

[0030] Specifically, Figure 2As shown, the adjustment mechanism includes an arc-shaped adjustment piece 5 and an adjustment bolt. The arc-shaped adjustment piece 5 is provided with a plurality of adjustment holes 6 arranged along its length direction. A fixing seat 8 is installed at the front end of the arc-shaped main body cover 1 through a hinge 7. The fixing seat 8 is fixedly installed on the top of the truck cab. An adjustment plate 9 is extended rearward from the fixing seat 8. The adjustment plate 9 is provided with threaded holes. The threaded holes are aligned with the respective adjustment holes 6 and fixed by adjusting bolts to adjust the inclination angle of the arc-shaped main body cover 1.

[0031] The angle range of the arc-shaped main body cover 1 rotating along the fixing seat 8 through the hinge 7 is set to 0 to 15 degrees.

[0032] Specifically, the arc-shaped adjustment piece 5 is set to a three-part structure with four adjustment holes 6, so that the inclination angle of the arc-shaped main body cover 1 is adjusted by 5° for each adjustment of one hole, and finally it can be tightened by adjusting bolts. The structure is simple and the adjustable space is large.

[0033] It should be noted that the adjustment mechanism for the tilt angle of the arc-shaped main body cover 1 can also be electric adjustment, such as an electric cylinder, etc., depending on the specific situation.

[0034] Among them, the fairing is made of a composite material with superior strength and rigidity.
