Description

Technical Field

[0001] The utility model relates to the technical field of fairings, in particular to an adjustable fairing structure for commercial vehicles. Background Art

[0002] A fairing is an air guiding device installed on the top of the cab of a truck or a tractor-trailer. Its main function is to effectively reduce the air resistance of the truck when driving at high speed and reduce fuel consumption. During the process of carrying goods by the truck, the height of the goods is higher than that of the cab, there is a height difference and a certain gap, making the overall vehicle shape discontinuous and the streamline poor. When the truck is running at high speed, when the air flow above the cab hits the upper part in front of the closed carriage, a large separation is generated from the front edge of the carriage top, and the air resistance coefficient value increases accordingly. Therefore, it is more necessary for the truck to install a fairing;

[0003] For example, the published patent No. CN117734839A discloses "an adjustable fairing structure for commercial vehicles and a commercial vehicle" and specifically discloses: a fairing assembly, which is movably installed on the mounting frame to have a guiding state where it moves to the top of the cab, and the front end of the fairing assembly is rotatably connected to the rear end of the mounting frame, while the rear end of the fairing assembly is arranged opposite to the rear side of the cab in an avoidance state. However, in the above technology, when in use, adjusting the fairing is relatively cumbersome and not convenient enough, thus reducing the convenience of the fairing structure in use. Therefore, the utility model proposes an adjustable fairing structure for commercial vehicles to solve the above problems. Summary of the Utility Model

Specific embodiments

[0018] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] According to Figure 1 , 2 , as shown in Figures 3 and 4, this embodiment proposes an adjustable fairing structure for commercial vehicles, including a bottom plate 1. On both sides of the bottom plate 1, side plates 2 are installed. At one end inside the side plates 2, a rotating shaft 3 is installed. Outside the rotating shaft 3, a cover body 4 is arranged. On one side above the side plates 2, a guiding structure is provided. On the top end of the bottom plate 1, an adjusting mechanism is provided.

[0020] The adjusting mechanism includes a connecting rod 5, a fixed cavity 6, an installation cavity 7 and a transmission structure. The connecting rod 5 is installed below the cover body 4. A fixed cavity 6 is installed at the bottom end of the connecting rod 5. The installation cavity 7 is installed at the top end of the bottom plate 1. A transmission structure is arranged inside the installation cavity 7. The transmission structure includes a servo motor 8, a first bevel gear 9, a second bevel gear 10, a threaded rod 11, a threaded sleeve 12, a moving cavity 13, a hinge seat 14, a fixed rod 15, a movable sleeve 16 and a limiting structure. The servo motor 8 is installed below one side of the installation cavity 7. The first bevel gear 9 is installed below one side inside the installation cavity 7. The output end of the servo motor 8 is connected to one end of the first bevel gear 9. The second bevel gear 10 is meshed above the first bevel gear 9. A threaded rod 11 is installed at the top end of the second bevel gear 10. A threaded sleeve 12 is arranged on the outer side wall of the threaded rod 11. A moving cavity 13 is fixedly installed on the outer side wall of the threaded sleeve 12. The top end of the moving cavity 13 extends to the outside of the installation cavity 7. A hinge seat 14 is installed at the top end of the moving cavity 13. The fixed rod 15 is installed inside the fixed cavity 6. A movable sleeve 16 is arranged on the outer side wall of the fixed rod 15. The bottom end of the movable sleeve 16 is connected to the top end of the hinge seat 14. During use, start the servo motor 8 to drive the first bevel gear 9 to rotate. Since the first bevel gear 9 and the second bevel gear 10 are meshed with each other, the second bevel gear 10 is used to drive the threaded rod 11 to rotate. Since the threaded rod 11 and the threaded sleeve 12 form a threaded connection, the threaded sleeve 12 is driven to move. Then, under the limitation of the limiting groove 17 and the limiting block 18, the moving cavity 13 is driven to move by the threaded sleeve 12. At this time, the movable sleeve 16 is driven to move on the outer wall of the limiting groove 17 by the moving cavity 13. With the cooperation of the rotating shaft 3, the cover body 4 is driven to move by the guiding of the guiding rail 19 and the guiding block 20. Then, the cover body 4 can be adjusted to an appropriate height according to actual needs, and the cover body 4 can be adjusted according to the height of the goods, making the adjustment of the cover body 4 more convenient and fast, thus greatly improving the convenience of the flow guiding cover structure during use.

[0021] The limiting structure includes a limiting groove 17 and a limiting block 18. The limiting groove 17 is opened inside the installation cavity 7. A limiting block 18 is arranged inside the limiting groove 17. One end of the limiting block 18 is connected to the outer side of the moving cavity 13. The limiting grooves 17 are opened on both sides inside the installation cavity 7. The limiting grooves 17 are symmetrically distributed about the central axis of the installation cavity 7. During use, with the mutual cooperation between the limiting groove 17 and the limiting block 18, the movement of the moving cavity 13 can be limited during movement, making the movement of the moving cavity 13 more stable.

[0022] The guiding structure includes a guiding rail 19 and a guiding block 20. The guiding rail 19 is installed on one side above the side plate 2. The guiding block 20 is arranged inside the guiding rail 19. One end of the guiding block 20 is connected to one end of the cover body 4. The inner diameter of the guiding rail 19 is larger than the outer diameter of the guiding block 20. A sliding structure is formed between the guiding rail 19 and the guiding block 20. During use, the guiding block 20 moves inside the guiding rail 19, and the guiding of the guiding rail 19 and the guiding block 20 drives the cover body 4 to move, making the cover body 4 more stable and not prone to shaking during adjustment. At the same time, since the guiding rail 19 is relatively narrow, the resistance received during driving is small, thus greatly improving the stability of the fairing structure during use.

[0023] Working principle: When the fairing needs to be adjusted, start the servo motor 8 to drive the first bevel gear 9 to rotate. Since the first bevel gear 9 meshes with the second bevel gear 10, the second bevel gear 10 is used to drive the threaded rod 11 to rotate. Since a threaded connection is formed between the threaded rod 11 and the threaded sleeve 12, the threaded sleeve 12 is driven to move. Then, under the limitation of the limiting groove 17 and the limiting block 18, the moving cavity 13 is driven to move by the threaded sleeve 12. At this time, the moving cavity 13 drives the movable sleeve 16 to move on the outer wall of the limiting groove 17. With the cooperation of the rotating shaft 3, the guiding of the guiding rail 19 and the guiding block 20 drives the cover body 4 to move, and then the cover body 4 is adjusted to an appropriate height according to actual needs.
