[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, while "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0027] like Figure 1 As shown, this disclosure provides a rear wing device for a truck, which is installed at the rear of the cargo box 3. The rear wing device includes: an upper guide plate 1, which is detachably mounted on the top of the cargo door 31; a first connecting rod 4 and a first support rod 5. The upper guide plate 1 is hinged to the cargo door 31 through the first connecting rod 4 and supported by the first support rod 5. One end of the first connecting rod 4 is hinged to the side of the upper guide plate 1 that is close to the cargo door 31 when it is unfolded, and the other end is hinged to the cargo door 31. One end of the first support rod 4 is hinged to the side of the upper guide plate 1 that is away from the cargo door 31 when it is unfolded, and the other end is hinged to the cargo door 31.

[0028] Through the above technical solution, the upper guide plate 1 is installed on the box door 31. When it is in the unfolded state, it has a turbulence-disrupting effect. By guiding the airflow, it reduces the turbulence and eddies at the rear of the cargo box 3, making the vehicle more stable when driving at high speed and encountering crosswinds, thus improving driving safety. The upper guide plate 1 is set on the top of the box door 31 in an openable and closable manner through the first connecting rod 4 and the first support rod 5. It can be opened when driving and closed when loading and unloading goods, which can reduce the space occupied by the vehicle and avoid obstructing the opening of the box door 31.

[0029] As an optional implementation method, such as Figure 1-2 As shown, the tail fin device also includes a first mounting base 6, which is located on the top of the cargo box 31. One end of the first connecting rod 4 is hinged to the upper side of the first mounting base 6 and can rotate longitudinally along the hinge end, while the other end is hinged to the upper guide plate 1. One end of the first support rod 5 is hinged to the lower side of the first mounting base 6 and can rotate longitudinally along the hinge end, while the other end is hinged to the upper guide plate 1. The first connecting rod 4 and the first support rod 5 are connected to the same mounting base, which facilitates installation and disassembly and saves installation space. When the upper guide plate 1 is unfolded, the first connecting rod 4 and the first support rod 5 rotate upward along the first mounting base 6 to form a linkage mechanism, which together form a triangular support structure, causing the upper guide plate 1 to move upward and one side to fit against the top of the cargo box 3. When it needs to be closed, the first connecting rod 4 and the first support rod 5 rotate downward along the first mounting base 6 and overlap together, causing the upper guide plate 1 to detach from the cargo box 3 and move downward to an angle parallel to the cargo box 31 and fit against the cargo box 31. In other embodiments, the first connecting rod 4 may be connected to the first mounting base 6, one end of the first support rod 5 may be hinged to the upper guide plate 1, and the other end may extend to the bottom of the box door 31.

[0030] In addition, such as Figure 1-3 and Figure 5As shown, the tail fin device also includes an operating component 7. One end of the operating component 7 is hinged to the middle of the first support rod 5, and the other end extends to the lower part of the door 31 to control the opening and closing of the upper deflector 1. Since the upper deflector 1 is located at the top of the door 31 and is relatively high, it is inconvenient for operators to operate. Therefore, the operating component 7 is provided. One end of the operating component 7 extends to the lower part of the door 31. Operators control the first support rod 5 to move up and down through the operating component 7, thereby controlling the opening and closing of the upper deflector 1. In other embodiments, it can also be driven by a motor, allowing for remote control of the motor switch.

[0031] Optionally, two first mounting seats 6 are spaced apart along the extension direction of the upper guide plate 1. The operating component 7 includes a connecting shaft 71, a pull rod 72, a handle 73, and a connecting seat 74. The connecting shaft 71 is horizontally arranged between the two first mounting seats 6 and its two ends are respectively hinged to the two first support rods 5. The pull rod 72 is vertically arranged with the connecting shaft 71. One end of the pull rod 72 is rotatably connected to the connecting shaft 71, and the other end is rotatably connected to the handle 73. The connecting seat 74 is located at the lower part of the door 31. One end of the handle 73 is hinged to the connecting seat 74, and the other end is rotatably connected to the end of the pull rod 72. For example, the handle 73 is constructed in a T-shape. One end of the vertical section of the T-shape is hinged to the connecting seat 74, and one end of the horizontal section is constructed as a handle 76. The other end is rotatably connected to the end of the pull rod 72 to drive the pull rod 72 to move up and down. The first mounting seat 6 is provided with two supports for greater stability. Two first connecting rods 4 and two first support rods 5 are also provided. The two first support rods 5 are connected by a connecting shaft 71. The movement of the two first support rods 5 is controlled by a pull rod 72. When the upper guide plate 1 needs to be unfolded, push the handle 76 upward. The handle 73 rotates upward along the connecting seat 74, pushing the pull rod 72 upward. The pull rod 72 drives the two first support rods 5 upward through the connecting shaft 71, thereby driving the upper guide plate 1 to move. The upper guide plate 1 moves in conjunction with the first connecting rod 4 until the handle 73 is pushed to fit against the box door 31. At this time, the upper guide plate 1 is fitted against the top of the cargo box 3. When the upper guide plate 1 needs to be closed, pull the handle 73 downward. The pull rod 72 drives the first support rod 5 downward to rotate, thereby driving the upper guide plate 1 and the first connecting rod 4 downward. The upper guide plate 1 moves downward away from the top of the cargo box 3 and is parallel to and fitted against the box door 31.

[0032] Optionally, such as Figure 4 As shown, the tail fin device also includes a fixing device 12, which is detachably mounted on the connecting seat 74 and engaged with the handle 73. The fixing device 12 is used to fix the handle 73, prevent the upper guide plate 1 from moving due to the movement of the handle 73, and increase the stability of the support.

[0033] Optionally, such as Figure 5As shown, the connecting seat 74 has connecting plates 75 on both sides near the upper guide plate 1 to form a receiving groove for the handle 73 to enter and exit. The end of the connecting plate 75 away from the door 31 has a connecting hole. The fixing device 12 includes a fixing pin 121 and an elastic arc-shaped retaining ring 122. One end of the fixing pin 121 passes through the two connecting holes and extends out of the receiving groove. One end of the arc-shaped retaining ring 122 is hinged to the end of the fixing pin 121, and the other end is sleeved with the end of the fixing pin 121 that passes through the connecting hole. The handle 73 moves upward to push the upper guide plate 1 to After unfolding, insert the fixing pin 121 into the two connecting holes to lock the handle 73. Then pull the arc-shaped retaining ring 122 outward to attach one end of the arc-shaped retaining ring 122 to the end of the fixing pin 121 that passes through the connecting hole, thus fixing the fixing pin 121 and preventing it from coming off the connecting hole. When it is necessary to close the upper guide plate 1, simply pull one end of the arc-shaped retaining ring 122 to disengage it from the fixing pin 121 and then pull out the fixing pin 121. This is convenient to use. When not in use, the fixing pin 121 can also be inserted into the connecting hole for later use.

[0034] As an optional implementation method, such as Figure 1-3 As shown, the tail fin device also includes a side guide plate 2, a second connecting rod 9, and a second support rod 8. The side guide plate 2 is designed to be openably mounted on the side of the cargo door 31. The side guide plate 2 is hinged to the cargo door 31 via the second connecting rod 9 and supported by the second support rod 8. Both cargo doors 31 are equipped with an upper guide plate 1 and a side guide plate 2. The upper guide plate 1 and the side guide plate 2 on the two cargo doors 31 form an inwardly contracting trapezoidal structure, which has a turbulence-disrupting effect when deployed. By guiding the airflow, it reduces turbulence and eddies at the rear of the cargo box. It can be opened when driving and closed when loading and unloading, reducing the space occupied by the vehicle and avoiding obstruction of the opening of the cargo door 31.

[0035] Optionally, such as Figure 2 and Figure 6 As shown, the tail fin device also includes a second mounting base 10, which is located on the outer edge of the door 31. The second connecting rod 9 and the second support rod 8 are both connected to the second mounting base 10. The second connecting rod 9 and the second support rod 8 are connected to the same mounting base, which facilitates installation and disassembly and saves installation space.

[0036] Optionally, such as Figure 2 and Figure 6As shown, one end of the second connecting rod 9 is hinged to the side of the second mounting base 10 near the side edge of the door 31 and can rotate laterally along the hinge end; the other end is hinged to the side of the side guide plate 2 near the door 31 when it is unfolded. The second support rod 8 includes a support rod 82 and a gas spring 81. One end of the support rod 82 is hinged to the side of the second mounting base 10 away from the side edge of the door 31 and can rotate laterally along the hinge end; the other end is hinged to the side of the side guide plate 2 away from the door 31 when it is unfolded. The second mounting base 10 has a mounting plate 11 on the side away from the side edge of the door 31. One end of the mounting plate 11 extends out of the second mounting base 10 in a direction away from the door 31 and has a mounting hole. One end of the gas spring 81 is connected to the side of the second mounting base 10 near the side edge of the door 31. The mounting hole is hinged, and the other end is hinged to the side of the support rod 82. When the side guide plate 2 needs to be unfolded, the operator pushes the side guide plate 2 outward by hand. The second support rod 8 and the second connecting rod 9 rotate outward along the second mounting seat 10 to form a triangular support structure. One side of the side guide plate 2 abuts against the cargo box 3. At the same time, the gas spring 81 unfolds. The gas spring 81, the mounting plate 11, and the second support rod 8 together form a triangular support structure to fix and support the second support rod 8. When the side guide plate 2 needs to be closed, push the side guide plate 2 inward or pull the gas spring 81 inward to make the second support rod 8 and the second connecting rod 9 rotate inward along the second mounting seat 10. The side guide plate 2 moves inward and fits against the box door 31. In actual use, the upper guide plate 1 should be closed first, and then the side guide plate 2 should be closed. The side guide plate 2 presses on the upper guide plate 1. In order to avoid the mounting plate 11 and the gas spring 81 from hindering the closing of the upper guide plate 1, the second mounting base 10 located above can be connected only to the second connecting rod 9 without connecting the second support rod 8.

[0037] This disclosure also provides a truck, including: the aforementioned truck tail wing device, the tail wing device having a turbulence-disrupting effect, reducing turbulence and eddies at the rear of the cargo box 3 by guiding airflow, making the vehicle more stable when driving at high speed and encountering crosswinds, and improving driving safety.
