Description
Technical Field
[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a vehicle rear panel assembly and a vehicle. Background Technology
[0002] With the development of automobile models and the expansion of automobile uses and usage scenarios, various types of rear tow hooks have become an important standard or optional configuration for many models. In related technologies, rear tow hooks are generally directly connected to the underbody, which is mainly a thin sheet metal stamping and spot welding structure. The structural strength is poor and it is difficult to meet the installation and strength requirements of rear tow hooks. Utility Model Content
[0003] The purpose of this disclosure is to provide a vehicle rear panel assembly and a vehicle to solve the technical problems existing in the related art.
[0004] To achieve the above objectives, the first aspect of this disclosure provides a vehicle rear panel assembly, including an inner rear panel, an outer rear panel, a rear tow hook assembly, and a reinforcing member. The inner rear panel and the outer rear panel are enclosed to form a cavity structure with a first cavity inside. The reinforcing member is disposed in the first cavity and is connected to the inner wall of the inner rear panel and the inner wall of the outer rear panel, respectively.
[0005] The rear tow hook assembly is mounted on the outer wall of the rear inner panel and connected to the reinforcing member located in the first cavity.
[0006] Optionally, the reinforcing member is constructed as a cavity structure with a second cavity formed inside.
[0007] Optionally, the reinforcing member includes a first reinforcing part and a second reinforcing part that are connected to each other, and a second cavity is formed between the first reinforcing part and the second reinforcing part. The shape of the first reinforcing part is adapted to the shape of the inner rear panel, and the first reinforcing part is attached to and welded to the inner wall of the inner rear panel. The shape of the second reinforcing part is adapted to the shape of the outer rear panel, and the second reinforcing part is attached to and welded to the inner wall of the outer rear panel.
[0008] Optionally, the vehicle rear panel assembly further includes at least one support member, one end of which is connected to the side of the reinforcing member near the inner rear panel, and the other end of which is connected to the side of the reinforcing member near the outer rear panel.
[0009] Optionally, the support member includes a support plate and a first flange formed on the edge of the support plate, the first flange and the support plate forming a shell-like structure, the first flange overlapping the inner wall of the reinforcing member.
[0010] Optionally, the rear tow hook assembly is detachably connected to the rear inner panel.
[0011] Optionally, the rear tow hook assembly includes a bolt and a rear tow hook assembly. A through hole is provided on the rear inner panel, and a mounting hole is formed on the rear tow hook assembly. The bolt passes through the mounting hole and the through hole in sequence and connects the rear tow hook assembly to the rear inner panel.
[0012] Optionally, the rear tow hook assembly further includes a threaded sleeve with a threaded hole inside. The threaded sleeve is disposed on the side of the reinforcing member away from the rear inner panel, and the threaded hole is coaxially arranged with the through hole. The bolt passes through the through hole and is threadedly connected to the threaded hole.
[0013] Optionally, the rear tow hook assembly further includes a connecting frame, which includes a first connecting plate, an intermediate plate, and a second connecting plate. The intermediate plate is connected to the first connecting plate and the second connecting plate. The first connecting plate overlaps with the side of the reinforcing member near the inner rear panel, and the second connecting plate overlaps with the side of the reinforcing member near the outer rear panel. The threaded sleeve is connected to the intermediate plate.
[0014] A second aspect of this disclosure provides a vehicle including the vehicle rear bulkhead assembly as described above.
[0015] Through the above technical solution, the reinforcing member is set within the cavity structure formed by the inner and outer rear panels, and the reinforcing member is connected to the inner walls of the inner and outer rear panels, so that the inner and outer rear panels can form an integral structure. The rear tow hook assembly is connected to the inner rear panel and the reinforcing member respectively. On the one hand, when the rear tow hook assembly is subjected to tension, the tension is transmitted to the inner rear panel and the reinforcing member, and then distributed to the outer rear panel through the reinforcing member. This allows the reinforcing member, the inner rear panel, and the outer rear panel to jointly distribute and transmit the load from the rear tow hook assembly. The tension of the rear tow hook assembly is no longer only applied to a local area of the inner rear panel, thereby reducing local stress concentration and improving the overall connection strength. On the other hand, the presence of the reinforcing member allows the entire vehicle rear panel assembly to better resist deformation when subjected to torsional force, improving the bending resistance of the inner rear panel, thereby improving the overall strength and durability of the vehicle rear panel assembly and protecting the structural safety of the vehicle.

Detailed Implementation
[0023] 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.
[0024] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," and "right" are used to indicate orientation or positional relationships only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation structure and operation, and therefore should not be construed as a limitation of this disclosure. The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures.
[0025] Additionally, it should be noted that the terms used, such as "first" and "second," are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description referring to the accompanying drawings, the same reference numerals in different drawings denote the same element.
[0026] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0027] refer to Figures 1 to 3 As shown, the first aspect of this disclosure provides a vehicle rear panel assembly 1, including an inner rear panel 10, an outer rear panel 20, a rear tow hook assembly 30, and a reinforcing member 40. The inner rear panel 10 and the outer rear panel 20 are enclosed to form a cavity structure with a first cavity 11 inside. The reinforcing member 40 is disposed in the first cavity 11 and is connected to the inner wall of the inner rear panel 10 and the inner wall of the outer rear panel 20, respectively. The rear tow hook assembly 30 is mounted on the outer wall of the inner rear panel 10 and is connected to the reinforcing member 40 located in the first cavity 11.
[0028] Through the above technical solution, the reinforcing member 40 is disposed within the cavity structure formed by the rear inner panel 10 and the rear outer panel 20, and the reinforcing member 40 is connected to the inner walls of the rear inner panel 10 and the rear outer panel 20, so that the rear inner panel 10 and the rear outer panel 20 can form an integral structure. Furthermore, the rear tow hook assembly 30 is connected to the rear inner panel 10 and the reinforcing member 40 respectively. On the one hand, when the rear tow hook assembly 30 is subjected to tension, the tension will be transmitted to the rear inner panel 10 and the reinforcing member 40, and then distributed to the rear outer panel 20 through the reinforcing member 40. This allows the reinforcing member 40, the inner rear panel 10, and the outer rear panel 20 to jointly distribute and transmit the load from the rear tow hook assembly 30. The tension of the rear tow hook assembly 30 is no longer applied only to a local area of the inner rear panel 10, thereby reducing local stress concentration and improving the overall connection strength. On the other hand, the presence of the reinforcing member 40 enables the entire vehicle rear panel assembly 1 to better resist deformation when subjected to torsional force, improving the bending resistance of the inner rear panel 10, thereby improving the overall strength and durability of the vehicle rear panel assembly 1 and protecting the structural safety of the vehicle.
[0029] To improve the structural strength of the aforementioned reinforcing member 40, such as Figure 1 , Figure 2 As shown, in one exemplary embodiment provided in this disclosure, the reinforcing member 40 is constructed as a cavity structure in which a second cavity 400 can be formed. On the one hand, setting the reinforcing member 40 as a hollow cavity structure can reduce the overall weight of the reinforcing member 40 while ensuring structural strength, and can reduce processing costs, thereby achieving lightweighting of the entire vehicle rear panel assembly 1; on the other hand, the presence of the second cavity 400 can provide better energy absorption during a collision, help disperse impact force, reduce damage to other parts of the vehicle body, and further improve vehicle safety.
[0030] Alternatively, in other embodiments provided in this disclosure, the aforementioned reinforcing member 40 may also be formed as a plate-like structure, i.e., a reinforcing plate. In order to improve the strength of the plate-like reinforcing plate, multiple reinforcing ribs or reinforcing bars may be provided on the outer wall of the reinforcing plate.
[0031] Specifically, in the embodiments provided in this disclosure, optionally, such as Figure 2 As shown, the reinforcing member 40 may include a first reinforcing part 41 and a second reinforcing part 42 connected to each other. A second cavity 400 is formed between the first reinforcing part 41 and the second reinforcing part 42. The shape of the first reinforcing part 41 is adapted to the shape of the inner rear panel 10, and the first reinforcing part 41 is attached to and welded to the inner wall of the inner rear panel 10. The shape of the second reinforcing part 42 is adapted to the shape of the outer rear panel 20, and the second reinforcing part 42 is attached to and welded to the inner wall of the outer rear panel 20. The adaptation of the shape of the first reinforcing part 41 to the shape of the inner rear panel 10 and the adaptation of the shape of the second reinforcing part 42 to the shape of the outer rear panel 20 ensures a tight fit between them and the inner walls of the inner rear panel 10 and the outer rear panel 20, so that the force can be evenly distributed between the two reinforcing parts, avoiding local damage caused by excessive force at a single point. Meanwhile, the second cavity 400 formed by their enclosure helps to guide the impact force to a wider area. In addition, the mutual fit of the first reinforcing part 41 and the inner rear panel 10, and the second reinforcing part 42 and the outer rear panel 20 also facilitates welding operations between the above structures.
[0032] To improve the structural strength of the aforementioned reinforcing member 40, in one embodiment provided in this disclosure, such as... Figures 1 to 3 As shown, the vehicle rear panel assembly 1 also includes at least one support member 50. One end of the support member 50 is connected to the side of the reinforcing member 40 near the inner rear panel 10, and the other end of the support member 50 is connected to the side of the reinforcing member 40 near the outer rear panel 20. By providing the support member 50 between the inner rear panel 10 and the outer rear panel 20, the loads from the inner rear panel 10 and the outer rear panel 20 can be better distributed and transferred, reducing local stress concentration and improving the deformation resistance of the vehicle rear panel assembly 1 under dynamic and static conditions. In addition, the presence of the support member 50 can also improve the impact resistance of the vehicle rear panel assembly 1, enhance the rigidity of the overall structure, and ensure that the inner rear panel 10 and the outer rear panel 20 can maintain better shape and function under collision or other external forces, thereby improving the safety and durability of the vehicle.
[0033] In one exemplary embodiment provided in this disclosure, such as Figure 2 As shown, the number of the above-mentioned support members 50 can be three, with two support members 50 spaced apart between the inner rear panel 10 and the outer rear panel 20 along the length direction of the reinforcing member 40.
[0034] In the embodiment where the reinforcing member 40 has a second cavity 400 inside, the supporting member 50 can be disposed inside the second cavity 400 and abut against the two opposing inner walls of the reinforcing member 40.
[0035] Optionally, such as Figure 3As shown, the support member 50 may include a support plate 51 and a first flange 52 formed on the edge of the support plate 51. The first flange 52 and the support plate 51 are formed into a shell structure, and the first flange 52 overlaps with the inner wall of the reinforcing member 40. When connecting the support member 50 and the inner wall of the reinforcing member 40, the first flange 52 formed on the edge of the support plate 51 can increase the contact area between it and the inner wall of the reinforcing member 40, thereby facilitating the welding operation between the two.
[0036] In this disclosure, the rear tow hook assembly 30 is detachably connected to the rear inner panel 10. On the one hand, the detachable connection of the rear tow hook assembly 30 to the rear inner panel 10 facilitates the inspection and maintenance of the rear tow hook assembly 30. Furthermore, when the rear tow hook assembly 30 is not needed, it can be removed to avoid occupying rear space of the vehicle and reduce potential safety hazards. On the other hand, the detachable design allows users to select different types or specifications of tow hooks as needed to adapt to different towing needs or usage scenarios, increasing the versatility of the vehicle.
[0037] Additionally, it should be noted that, as Figures 1 to 2 As shown, this disclosure does not limit the specific detachable method between the rear tow hook assembly 30 and the rear inner panel 10. For example, in an exemplary embodiment provided in this disclosure, the rear tow hook assembly 30 and the rear inner panel 10 can be connected by fasteners. Specifically, the rear tow hook assembly 30 includes bolts and a rear tow hook assembly 32. The rear inner panel 10 is provided with a through hole 12, and the rear tow hook assembly 32 is formed with a mounting hole 3220. The bolts are sequentially inserted into the mounting hole 3220 and the through hole 12 to connect the rear tow hook assembly 32 to the rear inner panel 10. By sequentially inserting the bolts into the mounting hole 3220 and the through hole 12, the rear tow hook assembly 32 is locked onto the rear inner panel 10, thereby fixing the rear tow hook assembly 32.
[0038] Alternatively, in another exemplary embodiment provided in this disclosure, the rear tow hook assembly 30 and the rear inner panel 10 can also be connected by a snap-fit method. Specifically, a snap-fit block is formed on one of the rear tow hook assembly 30 and the rear inner panel 10, and a snap-fit groove is formed on the other of the rear tow hook assembly 30 and the rear inner panel 10, and the snap-fit block is snapped into the snap-fit groove.
[0039] This disclosure does not limit the specific structure of the rear tow hook assembly 32, such as Figure 1 , Figure 2 As shown, in one embodiment provided in this disclosure, the rear tow hook assembly 32 may include a rear tow hook body 321 and a mounting bracket 322. The rear tow hook assembly 32 is connected to the mounting bracket 322. The mounting bracket 322 has the aforementioned mounting hole 3220. Bolts are inserted into the mounting bracket to fix the mounting bracket 322 and the rear tow hook body 321 connected to the mounting bracket 322 to the rear inner panel 10.
[0040] Optionally, the rear tow hook assembly 30 may also include a threaded sleeve 33, which has a threaded hole 330 inside. The threaded sleeve 33 is located on the side of the reinforcing member 40 opposite to the rear inner panel 10, and the threaded hole 330 is coaxially arranged with the through hole 12. Bolts pass through the through hole 12 and are threadedly connected to the threaded hole 330. When the rear tow hook assembly 30 is fixed by bolts, the fit between the threaded sleeve 33 and the threaded hole 330 can provide stronger connection strength, ensuring that the rear tow hook assembly 32 can withstand greater tensile and impact forces during use, thereby improving overall safety.
[0041] To further improve the pull-out resistance of the rear tow hook assembly 32, in one exemplary embodiment provided in this disclosure, the rear tow hook assembly 30 may further include a connecting frame 34. The connecting frame 34 includes a first connecting plate 341, an intermediate plate 342, and a second connecting plate 343. The intermediate plate 342 is connected to the first connecting plate 341 and the second connecting plate 343. The first connecting plate 341 overlaps with the side of the reinforcing member 40 near the rear inner panel 10, and the second connecting plate 343 overlaps with the side of the reinforcing member 40 near the rear outer panel 20. The threaded sleeve 33 is connected to the intermediate plate 342. The design of the connecting frame 34 can distribute the drag force at the threaded sleeve 33 to multiple connection points. The first connecting plate 341, the intermediate plate 342, and the second connecting plate 343 jointly distribute the drag force of the rear tow hook assembly 30, thereby reducing stress concentration at a single connection point and avoiding local fatigue damage to the rear inner panel 10 due to weight concentration in one place.
[0042] A second aspect of this disclosure provides a vehicle including the aforementioned rear panel assembly 1. This vehicle possesses all the beneficial effects of the aforementioned rear panel assembly 1, which will not be elaborated upon herein.
[0043] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0045] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
