Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically, to a tail wing structure and a vehicle. Background Technology

[0002] Most vehicle rear wings are optional accessories. When a vehicle is traveling at high speed, the rear wing can change the direction of airflow, thereby generating downward pressure. This downward pressure helps to increase the vehicle's grip on the ground, thus improving driving stability.

[0003] Tail fins are typically assembled from upper and lower fins, with a gap between them forming a cavity. To ensure the structural strength of the tail fin, some related technologies incorporate reinforcing ribs and connecting bosses within the cavity. However, these reinforcing ribs and connecting bosses are placed in areas where the tail fin's structural strength is relatively weak, which can easily lead to localized stress concentration and affect the tail fin's operational stability. Utility Model Content

[0037] like Figure 1-9 As shown in the figure, the tail fin structure provided in this embodiment of the present invention includes an upper fin plate 1, a lower fin plate 2, and a reinforcing plate 3, which are stacked and connected in sequence. The reinforcing plate 3 has multiple rib structures on its body, which are formed by multiple parts of the reinforcing plate 3 protruding to the same side. The rib structures are connected to one of the upper fin plate 1 and the lower fin plate 2, and the non-protruding parts of the reinforcing plate 3 are connected to the other of the upper fin plate 1 and the lower fin plate 2.

[0038] In this embodiment, multiple rib structures are provided on the plate body of the reinforcing plate 3. The multiple rib structures are formed by multiple parts of the plate body of the reinforcing plate 3 protruding to the same side. That is, each rib structure is formed by a part of the plate body of the reinforcing plate 3 protruding to the same side of the plate body. The protruding plate surface of the rib structure is connected to one of the upper wing plate 1 and the lower wing plate 2, while the non-protruding plate surface is connected to the other of the upper wing plate 1 and the lower wing plate 2. The connection part is mainly the bonding connection between the plate surfaces, which can effectively disperse stress and reduce the risk of stress concentration.

[0039] Moreover, the upper wing plate 1, the reinforcing plate 3, and the lower wing plate 2 are stacked and connected in sequence. The reinforcing plate 3 is located between the upper wing plate 1 and the lower wing plate 2, and its shape and size can be comparable to the upper wing plate 1 and the lower wing plate 2. That is, the plate body of the reinforcing plate 3 can extend from the left end to the right end and from the front end to the rear end of the tail fin, so that the connecting and bonding surface between the reinforcing plate 3, the upper wing plate 1, and the lower wing plate 2 can fully cover the length and width directions of the tail fin, thereby effectively improving the bending stiffness and overall strength of the tail fin.

[0040] Furthermore, the rib structure formed by these protrusions on the reinforcing plate 3 cleverly utilizes the gap cavity between the upper wing plate 1 and the lower wing plate 2, effectively improving the structural strength of the reinforcing plate 3 itself. Compared with the reinforcing ribs and connecting boss structures mentioned in the background art, the entire reinforcing plate 3 has a simple structure, is easy to manufacture, and only requires a single integrated part, making the assembly process of the tail fin simple and efficient.

[0041] Optionally, the multiple rib structures include a first rib 31 disposed at the front edge of the reinforcing plate 3 and a second rib 32 disposed at the rear edge of the reinforcing plate 3, as well as a rib block 33 disposed between the first rib 31 and the second rib 32.

[0042] A first rib 31 is provided at the front edge of the reinforcing plate 3, and a second rib 32 is provided at the rear edge of the reinforcing plate 3. A rib block 33 is provided on the plate body of the reinforcing plate 3 between the first rib 31 and the second rib 32. The first rib 31, the rib block 33, and the second rib 32 are arranged sequentially from front to back along the width direction of the tail fin, so that the connecting and bonding surfaces between the reinforcing plate 3, the upper wing plate 1, and the lower wing plate 2 can cover the width direction of the tail fin relatively evenly, thereby effectively improving the bending stiffness and overall strength of the tail fin.

[0043] Optionally, the reinforcing plate 3 includes a plurality of ribs 33 spaced apart along the left and right directions of the vehicle body, wherein the first rib 31, the second rib 32 and the ribs 33 at both ends smoothly transition to the plate body at the left and right ends of the reinforcing plate 3.

[0044] In this optional embodiment, such as Figure 2 and Figure 3 As shown, several ribs 33 are spaced apart along the left-right direction of the vehicle body. This arrangement of ribs 33 along the entire length of the wingplate, i.e., the left-right direction of the vehicle body, significantly increases the bending stiffness and overall strength of the reinforcing plate 3. Furthermore, the first rib 31, the second rib 32, and the ribs 33 at both ends smoothly transition into the side edges of the reinforcing plate 3. Since the upper wingplate 1 and the lower wingplate 2 need to be fitted and fixed at their left and right ends, the side edges of the reinforcing plate 3 are approximately flat, as shown... Figure 8 As shown, a smooth transition can improve the appearance and processability of the reinforcing plate 3, and also avoid stress concentration.

[0045] In addition, the first rib 31, multiple ribs 33 and the second rib 32 are arranged from left to right along the body of the reinforcing plate 3, i.e. the length direction of the tail fin, so that the connecting and bonding surfaces between the reinforcing plate 3, the upper wing plate 1 and the lower wing plate 2 can cover the length direction of the tail fin more evenly, thereby effectively improving the bending stiffness and overall strength of the tail fin.

[0046] Specifically, the smooth transition between the first rib 31 and the side edge of the reinforcing plate 3 is achieved by gradually reducing the height of the protrusions at both ends of the first rib 31 until it reaches zero. The second rib 32 and the ribs 33 at both ends can also have their protrusion height gradually reduced until zero, thus achieving a smooth transition to the side edge of the plates at both ends.

[0047] Optionally, the top and / or bottom surfaces of the reinforcing plate 3 are provided with adhesive-blocking grooves, which are formed by strip-shaped protrusions on the surface of the reinforcing plate 3.

[0048] In this optional embodiment, the reinforcing plate 3, the upper wing plate 1, and the lower wing plate 2 are fixedly connected by adhesive. A glue-blocking groove is provided on the top or bottom surface of the reinforcing plate 3 to facilitate adhesive application and prevent glue loss. Furthermore, the glue-blocking groove is formed by a strip-shaped protrusion on the surface of the reinforcing plate 3, eliminating the need for slotting on the reinforcing plate 3 and avoiding affecting its strength. The height of this strip-shaped protrusion is generally small.

[0049] Optionally, the first rib 31, the second rib 32, and the rib block 33 are connected to the upper wing plate 1, and the reinforcing plate 3 between the first rib 31, the second rib 32, and the rib block 33 is connected to the lower wing plate 2.

[0050] In this embodiment, the first rib 31, the second rib 32, and the rib block 33 are all formed by the upward protrusion of the reinforcing plate 3. The first rib 31, the second rib 32, and the rib block 33 are connected to the upper wing plate 1. The reinforcing plate 3 between the first rib 31, the second rib 32, and the rib block 33 is connected to the lower wing plate 2. That is, on the plate body of the reinforcing plate 3, the plate surface with the protruding rib structure is connected to the upper wing plate 1, while the plate surface without protrusion is connected to the lower wing plate 2. The connection part is mainly the bonding connection between the plate surfaces, which can effectively disperse stress and reduce the risk of stress concentration.

[0051] Optionally, a first adhesive-blocking groove 41 is provided on the top surface of the reinforcing plate 3. The first adhesive-blocking groove 41 is annular and arranged around the edge of the top surface of the reinforcing plate 3.

[0052] In this optional embodiment, such as Figure 2 As shown, the reinforcing plate 3 and the upper wing plate 1 are bonded and fixed together. The first adhesive groove 41 facilitates the application of adhesive to the reinforcing plate 3, preventing adhesive loss. Specifically, the first adhesive groove 41 is an annular groove structure that wraps around the outer edge of the reinforcing plate 3, so that the bonding part between the reinforcing plate 3 and the upper wing plate 1 also wraps around the outer edge of the reinforcing plate 3, and the bonding is carried out along the entire length of the tail wing, resulting in a firm and reliable bond.

[0053] Optionally, the first adhesive groove 41 is composed of two annular first adhesive strips 401 arranged at intervals.

[0054] In this optional embodiment, such as Figure 2-8 As shown, the first adhesive groove 41 is composed of two annular first adhesive strips 401 arranged at intervals. That is, the groove structure formed between the two annular first adhesive strips 401 is the first adhesive groove 41. The first adhesive strips 401 are all annular and arranged around the top edge of the reinforcing plate 3. The first adhesive strip 401 is a strip-shaped protrusion set on the top surface of the reinforcing plate 3. The height of this strip-shaped protrusion is generally small. In addition, the spacing between the two first adhesive strips 401 is adaptively designed according to the actual adhesive force requirements, the edge size of the reinforcing plate 3, etc.

[0055] Optionally, such as Figure 3 As shown, the first adhesive groove 41 includes a front end section 411 disposed on the first rib 31, a rear end section 412 disposed on the second rib 32, and a side section 413 disposed on the left and right ends of the top surface of the reinforcing plate 3.

[0056] The entire first adhesive groove 41 consists of four sections. The front end section 411 is located on the top surface of the first rib 31. The adhesive liquid stored in the front end section 411 can bond the top surface of the first rib 31 to the upper wing plate 1. The rear end section 412 is located on the second rib 32. The adhesive liquid stored in the rear end section 412 can bond the top surface of the second rib 32 to the upper wing plate 1. There are two side sections 413, one on each side, located on the side edge of the reinforcing plate 3.

[0057] Optionally, a second adhesive groove 42 is also provided on the top surface of the reinforcing plate 3, and the second adhesive groove 42 is located on the rib 33.

[0058] In this optional embodiment, a glue-blocking groove is also provided on the top surface of each rib 33 to facilitate the application of adhesive for bonding with the upper wing 1. Specifically, the second glue-blocking groove 42 can be in the shape of a long rectangular strip, and the long rectangular second glue-blocking groove 42 is arranged along the left and right direction of the vehicle body so that the bonding area extends along the length direction of the tail wing, increasing the bonding area and bonding strength.

[0059] Optionally, the second adhesive groove 42 is composed of a second adhesive strip 402, such as... Figure 3-8 As shown, the second rubber strip 402 is a rectangular ring, which is a strip-shaped protrusion set on the top surface of the rib 33. The height of this strip-shaped protrusion is generally small.

[0060] Optionally, a plurality of third adhesive grooves 43 are provided on the bottom surface of the reinforcing plate 3, and the third adhesive grooves 43 are provided on the non-protruding parts of the reinforcing plate 3.

[0061] In this optional embodiment, such as Figure 3-9 As shown, the reinforcing plate 3 and the lower wing plate 2 are also bonded together. Multiple third adhesive grooves 43 are provided, all of which are annular, to facilitate the application of adhesive to the bottom surface of the reinforcing plate 3, so as to facilitate the bonding of the reinforcing plate 3 and the lower wing plate 2.

[0062] Optionally, each third groove 43 surrounds one or more ribs 33.

[0063] In this optional embodiment, the third adhesive groove 43 is annular, and each third adhesive groove 43 surrounds one or more ribs 33. The ribs 33 are spaced apart along the left and right direction of the vehicle body. The third adhesive grooves 43 do not overlap or cross each other. In this way, the third adhesive grooves 43 and the bonding area are also arranged along the left and right direction of the vehicle body, so that the adhesive area is more evenly distributed and the bonding strength is high.

[0064] like Figure 9 As shown, there are six ribs 33 and three third glue grooves 43. Each third glue groove 43 surrounds two ribs 33, and a long rectangular fourth glue groove 44 is provided between the two ribs 33 surrounded by each third glue groove 43.

[0065] Optionally, the third adhesive groove 43 is composed of two annular third adhesive strips 403 arranged at intervals. The third adhesive strips 403 are both annular and are strip-shaped protrusions set on the bottom surface of the reinforcing plate 3. The height of these strip-shaped protrusions is generally small.

[0066] Optionally, the first rib 31 has a U-shaped cross-section, and the bottom plate of the U-shaped cross-section is connected to the upper flange 1.

[0067] In this optional embodiment, such as Figure 4-7 As shown, the first rib 31 has a U-shaped cross-section, which increases the bending stiffness of the reinforcing plate 3, reduces the deflection deformation of the plate under load, and makes the load more evenly distributed on the entire plate, avoiding local stress concentration. Specifically, the first rib 31 is long and strip-shaped, arranged along the length of the tail wing, i.e., the left and right direction of the vehicle body, extending to both ends of the tail wing and smoothly transitioning with the left and right edge edges of the reinforcing plate 3.

[0068] In addition, the bottom plate of the U-shaped section of the first rib 31 is connected to the upper flange 1 by adhesive bonding. The U-shaped bottom plate of the first rib 31 is provided with a glue-blocking groove for applying adhesive. The specific structure can be as described above for the front end section 411. Figure 3 As shown.

[0069] Optionally, such as Figure 3-8 As shown, the cross-sectional shape of the second rib 32 includes U-shape and V-shape. The bottom plate of the U-shaped section and the side plate away from the first rib 31 are used to connect with the upper wing plate 1, and the side plate of the V-shaped section away from the first rib 31 is used to connect with the upper wing plate 1.

[0070] U-shaped ribs typically have a larger cross-sectional area, providing better load-bearing capacity and bending stiffness; their shape allows the ribs to better distribute the load and reduce stress concentration. In contrast, V-shaped ribs have a relatively smaller cross-sectional area, but offer higher stiffness and strength in certain directions.

[0071] In this optional embodiment, the cross-sectional shape of the second rib 32 is designed to be variable, allowing for optimal design based on the stress conditions and spatial arrangement in different areas. In areas with higher stress, the cross-sectional area of ​​the rib can be increased to improve load-bearing capacity; while in areas with lower stress, the cross-sectional area can be reduced to save material. This design not only ensures the stability of the structure under different stress conditions but also improves material utilization and enhances the overall structural strength. The second rib 32 is also elongated, arranged along the length of the tail wing, i.e., the left-right direction of the vehicle body, extending to both ends of the tail wing. The height of the protrusions at both ends gradually decreases until they reach zero, achieving a smooth transition.

[0072] In addition, the connection between the second rib 32 and the upper wing plate 1 can be by bonding. The bottom plate of the U-shaped section of the second rib 32 and the side plate away from the first rib 31, as well as the side plate of the V-shaped section away from the first rib 31, are provided with adhesive-blocking grooves for applying adhesive. The specific structure can be as described in the rear end section 412 above.

[0073] Optionally, the second rib 32 includes a first segment 321, a second segment 322, a third segment 323, a fourth segment 324, and a fifth segment 325 connected in sequence. The cross-sections of the first segment 321, the third segment 323, and the fifth segment 325 are all V-shaped, and the cross-sections of the second segment 322 and the fourth segment 324 are all U-shaped.

[0074] In this optional embodiment, such as Figure 3 As shown, the second rib 32 is specifically designed as five segments, with the middle and two side segments using a V-shaped cross section and the other two segments using a U-shaped cross section.

[0075] In addition, such as Figure 3 As shown, several notches can be provided on the front sidewall of the first rib 31 and the second rib 32. These notches are used to avoid the fastening structure between the upper wing plate 1 and the lower wing plate 2. The adhesive-blocking groove at the notch is also broken, and the structural adhesive is viscous and will not flow out excessively from the notch, thus not affecting the bonding. The cross-section of the rib 33 is also U-shaped, and the width of its U-shaped cross-section is wider than that of the first rib 31.

[0076] In addition, it should be noted that this application does not restrict the shape of the reinforcing plate 3, that is, it does not restrict the specific shape, bending angle, etc. of the reinforcing plate 3; the reinforcing plate 3 is adapted to the upper wing plate 1 and the lower wing plate 2 to form the overall shape of the tail wing structure, so the shape of the reinforcing plate 3 can be matched according to the actual design.

[0077] This utility model embodiment also provides a vehicle having the above-described tail wing structure.

[0078] Because of the vehicle's technological improvements and the same technical effects as the tail wing structure, the connection between the reinforcing plate 3, the upper wing plate 1 and the lower wing plate 2 on the tail wing structure is mainly a bonding connection between the plate surfaces, which can effectively disperse stress and reduce the risk of stress concentration; moreover, the bonding surface can fully cover the length direction of the tail wing, effectively improving the bending stiffness and overall strength of the tail wing.

[0079] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
