Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an adjustable deflector structure and a vehicle. Background Art

[0002] To maximize cargo capacity, domestic heavy-duty truck users often use extra-wide trailers. However, when a heavy-duty truck cab leaves the factory or is licensed, its maximum external width must meet regulatory requirements. Because the trailer is significantly wider than the cab, the extra-wide portion experiences greater air resistance during driving, increasing fuel consumption.

However, they have poor stability and can only be used when parking to facilitate passengers to get on and off the workbench. The deflectors cannot be flipped out during driving, so they do not help with fuel economy.

[0004] Therefore, it is necessary to design an adjustable guide plate structure to solve the above technical problems. Utility Model Content

[0033] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0034] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0035] Next, the embodiments of this specification are described in detail.

[0036] Reference Figure 1 As shown, the present application discloses an adjustable deflector structure comprising a deflector 10 and a positioning assembly 20. The deflector 10 is rotatably mounted on a vehicle via the positioning assembly 20, and the deflector 10 is rotated outward to increase the width of the cab. For example, the deflector 10 can be mounted at the rear end of the cab. The vehicle referred to herein may be a trailer, heavy truck, or the like.

[0037] The deflector 10 comprises an upper deflector 11 and a lower deflector 12, which are connected to each other. The connection mentioned here can be snap-fitting, welding, or other methods. By dividing the deflector 10 into multiple pieces, the casting process is simplified and transport is facilitated. The length of the upper deflector 11 matches the height of the cab, while the length of the lower deflector 12 matches the height of the vehicle frame below the cab.

[0038] A plurality of partition cavities 13 are provided on the upper guide plate 11 and the lower guide plate 12. The partition cavities 13 not only reduce the overall weight of the guide plate 10 but also improve the rigidity and strength of the guide plate 10, effectively distribute and transmit force, and reduce deformation and stress concentration.

[0039] The adjustable guide plate structure further includes a cover plate 60 , which covers the outer side of the guide plate 10 to make the adjustable guide plate structure more beautiful as a whole.

[0040] To optimize aerodynamic performance and enhance driving stability, the vehicle's front end is designed to be wider at the bottom and narrower at the top. The wider lower portion provides better front stability and wind resistance, while the narrower upper portion helps reduce wind resistance and improve fuel efficiency. This design also enhances visibility and safety. Therefore, the width of the corresponding cover plate 60, located near the positioning assembly 20, gradually increases from bottom to top.

[0041] The positioning assembly 20 includes a first mounting bracket 21 and several second mounting brackets 22. Each of the first and second mounting brackets 211, 221, and rotatable brackets 212, 222 are configured to rotate relative to each other. The deflector 10 is secured to the rotatable brackets 222. The first mounting bracket 21 is equipped with a locking mechanism for locking the deflector's position, while the second mounting bracket 22 is equipped with an adjustment mechanism for adjusting the deflector's position. The locking and adjustment mechanisms work together to adjust the angle of the deflector 10 without the use of tools.

[0042] Reference Figure 2-4 As shown, the locking mechanism includes a latch 31 and a spring 32. The latch 31 passes through the fixed bracket 211 and the rotating bracket 212. The spring 32 is mounted outside the latch 31 and is retained between the end of the latch 31 and the rotating bracket 222. The rotating bracket 222 is provided with a retaining slot 2121. The latch 31 includes a lower section 312 with the same diameter as the retaining slot 2121 and an upper section 311 with a smaller diameter than the retaining slot 2121. The spring 32 is mounted outside the upper section 311. In the locked state, the lower section 312 is located within the retaining slot 2121. In the unlocked state, the upper section 311 is located within the retaining slot 2121.

[0043] The fixed bracket 221 is provided with a fixed post 33 that fits over the outside of the latch 31. The fixed post 33 allows the latch 31 to move up and down, ensuring stable movement of the latch 31. One end of the latch 31 is provided with a first stopper 313 that abuts the spring 32, and the other end of the latch 31 is provided with a second stopper 314 that abuts the rotating bracket 222.

[0044] Reference Figure 5 As shown, the adjustment mechanism includes a pair of limiting gears 41, a limiting bracket 42, and an elastic component. The pair of limiting gears 41 are fixed to the upper and lower sides of the fixed bracket 221, for example, by welding the limiting gears 41 to the upper and lower sides of the fixed bracket 221. Positioning the limiting gears 41 opposite to each other can stabilize the rotation of the limiting bracket 42.

[0045] A plurality of grooves 411 are provided on the limiting gear fan 41. One end of the limiting bracket 42 is rotatably connected to the rotating bracket 222. The other end of the limiting bracket 42 is provided with a limiting tooth 421. The limiting tooth 421 can move between the plurality of grooves 411 and is fixed in one of the grooves 411 through an elastic component.

[0046] The elastic assembly includes an elastic member 43 and a positioning shaft 44. The fixed bracket 221 includes a body 2211 and a positioning portion 2212 extending outward from one end of the body 2211 near the rotating bracket 222. The positioning shaft 44 is fixed to the end of the positioning portion 2212. The ends of the elastic member 43 are respectively fixed to the positioning shaft 44 and the other end of the limiting bracket 42. The elastic member 43 can be a spring or an elastic rubber member, etc.

[0047] Reference Figure 1 and Figure 5 As shown, the adjustable deflector structure also includes an adjusting rocker arm 50, which includes a connecting rod 51 installed on the limiting bracket 42 and a hand-held portion 52 protruding from the connecting rod 51, which facilitates operation by personnel.

[0048] The connecting rod 51 is provided with a plurality of mounting portions 53 , which respectively correspond to the limiting brackets 42 on the plurality of second mounting brackets 22 . The mounting portions 53 are mounted on the limiting brackets 42 by screws for easy disassembly.

[0049] There are three second mounting brackets 22, two of which are mounted on the upper guide plate 11, and one second mounting bracket 22 is mounted on the lower guide plate 12. The upper portion of the upper guide plate 11 is not rigid enough, so the thickness of the upper portion of the upper guide plate 11 is greater than that of the lower and middle portions.

[0050] A first mounting bracket 21 and multiple second mounting brackets 22 are installed between two adjacent partition chambers 13. The first mounting bracket 21 is positioned above the multiple second mounting brackets 22. This design is due to the fact that the vehicle's front end is wider at the bottom and narrower at the top, so the rotation axis above the front end and the rotation axis below the front end are not aligned in the same vertical direction. By installing another mounting bracket above, namely the first mounting bracket 21, the rotation axis is adjusted so that the first mounting bracket 21 and multiple second mounting brackets 22 can rotate about the same axis, thereby improving the rotational stability of the deflector 10.

[0051] The deflector 10 is fixed to the rotating brackets 212 and 222 with screws for easy removal. The rotating brackets 212 and 222, the fixed brackets 211 and 221, and the position-limiting bracket 42 are provided with weight-reducing holes 23. This reduces the overall weight of the rotating brackets 212 and 222, the fixed brackets 211 and 221, and the position-limiting bracket 42 while also increasing their rigidity and strength, effectively distributing and transmitting forces and reducing deformation and stress concentration.

[0052] The positioning assembly 20 of this application allows the deflector 10 to expand outward and adapt to vehicles of varying widths, enabling secure positioning at multiple angles, reducing the vehicle's drag coefficient and improving fuel economy. Simultaneously, the deflector 10 can be adjusted back to its original position to meet vehicle width requirements during vehicle registration or annual inspection. The locking and adjustment mechanisms are simple and easy to operate, allowing for tool-free adjustment.

[0053] The present application also provides a vehicle including the above-mentioned adjustable deflector structure, wherein the fixing brackets 221 and 211 are fixed to the rear end of the vehicle's cab. The deflector 10 can be fixed at multiple angles, thereby achieving matching of the cab with trailers of different widths.

[0054] The present application also discloses a method for adjusting an adjustable deflector structure: when the deflector 10 is in the initial position, first pull the latch 31 of the first mounting bracket 21 downward to unlock it, so that the upper section 311 of the latch 31 will move in the limiting slot 2121. Then manually move the adjustment rocker arm 50 to overcome the pulling force of the elastic member 43, so that the limiting tooth 421 in the limiting bracket 42 is disengaged from the groove 411 of the limiting tooth fan 41, so that the limiting tooth 421 moves. According to the requirements of the outward expansion size of the deflector 10, the limiting tooth 421 is allowed to slide into the corresponding groove 411 for limiting. At the same time, the lower section 312 of the latch 31 in the first mounting bracket 21 will move into the limiting slot 2121 and be fixed in position under the joint action of the elastic member 43. At this time, the upper side deflector 11 and the lower side deflector 12 will synchronously adjust the outward expansion angle.

[0055] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
