[0039] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0040] Reference below Figures 1-8 A rear impact beam assembly 10 according to an embodiment of the present invention is described.

[0041] like Figures 1-8 As shown, the rear anti-collision beam assembly 10 according to an embodiment of the present utility model includes: a rear anti-collision beam body 1 and an energy absorbing member 2.

[0042] Specifically, refer to Figure 1 and Figure 2 The energy absorbing member 2 is located on the lower side of the rear anti-collision beam body 1 and is connected to the rear anti-collision beam body 1. It should be noted that the up-down direction refers to the up-down direction of the vehicle. In the up-down direction of the vehicle, the energy absorbing member 2 is generally located on the lower side of the rear anti-collision beam body 1 and is arranged opposite to the rear anti-collision beam body 1. It can be understood that by providing the energy absorbing member 2, the rear anti-collision beam body 1 and the energy absorbing member 2 can jointly withstand the impact force, thereby improving the structural strength of the rear anti-collision beam assembly 10 and thus improving the protective effect of the vehicle.

[0043] At the same time, the energy absorbing member 2 is arranged on the lower side of the rear anti-collision beam body 1. Compared with the energy absorbing member and the rear anti-collision beam body being arranged in the front and rear directions of the vehicle, it is beneficial to save the front and rear dimensions of the vehicle, increase the front and rear space of the cockpit, and improve the user's riding experience.

[0044] Furthermore, if Figure 2 and Figure 3 As shown, the upper end of the energy absorbing member 2 and the lower end of the rear anti-collision beam body 1 are arranged opposite to each other in the thickness direction of the rear anti-collision beam body 1, wherein the upper end of the energy absorbing member 2 has an avoidance groove, and the lower end of the rear anti-collision beam body 1 is arranged in the avoidance groove. The width direction of the avoidance groove (as shown in FIG. Figure 1 Both side walls (in the front-to-back direction) are connected to the anti-collision beam body (e.g., by welding or fasteners), so that the upper end of the energy absorbing member 2 and the lower end of the rear anti-collision beam body 1 are arranged opposite each other in the thickness direction of the rear anti-collision beam body 1. This improves the connection reliability between the energy absorbing member 2 and the anti-collision beam body, further enhances the structural strength of the rear anti-collision beam assembly 10, and thus further improves the protective effect.

[0045] In addition, when the rear of the vehicle is subjected to a minor collision, the rear anti-collision beam body 1 is partially disposed in the avoidance groove, so that the energy absorbing member 2 is preferentially impacted and deformed, thereby protecting the rear anti-collision beam body 1, thereby reducing or avoiding deformation of the rear anti-collision beam body 1, reducing the number of replacements of the rear anti-collision beam body 1, and thus reducing maintenance costs.

[0046] According to the rear impact beam assembly 10 of the present invention, by locating the energy absorbing member 2 on the lower side of the rear impact beam body 1 and connecting it to the rear impact beam body 1, the rear impact beam body 1 and the energy absorbing member 2 can jointly withstand the impact force, thereby not only improving the structural strength of the rear impact beam assembly 10 and enhancing the protective effect of the vehicle, but also helping to save the front and rear dimensions of the vehicle, increasing the front and rear space of the cockpit, and improving the user's riding experience.

[0047] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 5 As shown, the energy absorbing members 2 are multiple and spaced apart along the length direction of the rear anti-collision beam body 1. Thus, the structural strength of the rear anti-collision beam assembly 10 is further improved, thereby further improving the protection effect.

[0048] Furthermore, the energy absorbing members 2 are provided in a plurality of locations spaced apart along the length of the rear anti-collision beam body 1. Compared to a single, integral energy absorbing member 2 extending along the length of the rear anti-collision beam body 1, this not only reduces the weight of the rear anti-collision beam assembly 10, saving vehicle costs and contributing to vehicle lightweighting, but also allows for the replacement of the energy absorbing member 2 corresponding to the impacted portion of the vehicle in the event of a minor collision. This further reduces maintenance costs compared to replacing an entire energy absorbing member 2.

[0049] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the rear anti-collision beam body 1 has a first cavity 11, and the first cavity 11 penetrates the rear anti-collision beam body 1 along the length direction of the rear anti-collision beam body 1. The first cavity 11 has at least one first reinforcing rib 12, and the first reinforcing rib 12 divides the first cavity 11 into multiple first sub-cavities 111, and each first sub-cavity 111 penetrates the rear anti-collision beam body 1 along the length direction of the rear anti-collision beam body 1.

[0050] Among them, it should be noted that the first reinforcing rib 12 extends along the length direction of the rear anti-collision beam body 1, so as to facilitate the division of the first cavity 11 into multiple first sub-cavities 111 that penetrate the rear anti-collision beam body 1 along the length direction of the rear anti-collision beam body 1. The first reinforcing rib 12 is spaced apart in the up and down directions of the vehicle, so that the multiple first sub-cavities 111 are spaced apart in the up and down directions of the vehicle.

[0051] It is understood that the provision of the first cavity 11 reduces the weight of the rear impact beam body 1. Furthermore, the provision of multiple first sub-cavities 111 effectively isolates vibration and noise from the rear impact beam body 1, enhancing NVH (Noise, Vibration, and Harshness) performance while also improving energy absorption. The provision of at least one first reinforcing rib 12 within the first cavity 11 further enhances the structural strength of the rear impact beam body 1, thereby increasing the structural strength of the rear impact beam assembly 10. This further reduces overall deformation of the rear impact beam assembly 10, protecting occupant safety.

[0052] For example, Figure 3 and Figure 4In the example shown, there are two first reinforcing ribs 12 and three first sub-cavities 111. However, the present invention is not limited thereto. The first reinforcing ribs 12 may be of other numbers, and the first sub-cavities 111 may be of other numbers. For example, the first reinforcing ribs 12 may be of one, three, five, or six numbers, and the first sub-cavities 111 may be of two, four, six, or seven numbers. It should be noted that the number of first sub-cavities 111 is the number of first reinforcing ribs 12 plus one.

[0053] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the energy absorbing member 2 has a second cavity 21, which penetrates the energy absorbing member 2 along the length direction of the rear anti-collision beam body 1. The second cavity 21 has at least one second reinforcing rib 22, which divides the second cavity 21 into multiple second sub-cavities 211, and each second sub-cavity 211 penetrates the energy absorbing member 2 along the length direction of the rear anti-collision beam body 1.

[0054] It should be noted that the second reinforcing rib 22 extends along the length direction of the rear anti-collision beam body 1, thereby facilitating the division of the second cavity 21 into a plurality of second sub-cavities 211 penetrating the energy absorbing member 2 along the length direction of the rear anti-collision beam body 1.

[0055] As can be appreciated, the provision of the second cavity 21 reduces the weight of the energy absorber 2. The multiple second sub-cavities 211 effectively isolate vibration and noise, improving NVH performance while also enhancing energy absorption. The inclusion of at least one second reinforcing rib 22 within the second cavity 21 further enhances the structural strength of the energy absorber 2, thereby improving the structural strength of the rear impact beam assembly 10. This further reduces overall deformation of the rear impact beam assembly 10, protecting occupant safety.

[0056] For example, Figure 3 In the example shown, there are three second reinforcing ribs 22 and four second sub-cavities 211. However, the present invention is not limited thereto. The number of second reinforcing ribs 22 and the number of second sub-cavities 211 may also be other numbers. For example, the number of second reinforcing ribs 22 may be 1, 2, 5, or 6, and the number of second sub-cavities 211 may be 2, 3, 6, or 7. It should be noted that the number of second sub-cavities 211 is the number of second reinforcing ribs 22 plus one.

[0057] In some embodiments of the present invention, Figures 1-8 As shown, the rear anti-collision beam assembly 10 also includes: an energy absorption box 3, and the energy absorption box 3 is arranged on the front side of the rear anti-collision beam body 1 and is connected to the rear anti-collision beam body 1, and the front end of the energy absorption box 3 is connected to a connecting plate 33, which is suitable for connecting to the rear longitudinal beam of the vehicle (not shown), for example, by welding or fasteners.

[0058] It can be understood that when the rear of the vehicle is subjected to a strong impact, the crushing deformation of the crash box 3 can absorb some of the impact force, thereby improving protection for the user. The provision of the connecting plate 33 increases the connection area between the crash box 3 and the rear longitudinal beam, reducing stress concentration between the crash box 3 and the rear longitudinal beam.

[0059] In some embodiments of the present invention, Figures 1-8 As shown, the rear anti-collision beam assembly 10 further includes a reinforcing plate 4 , which is located on the outer peripheral side of the energy absorption box 3 and connected to the outer peripheral wall of the energy absorption box 3 and the connecting plate 33 .

[0060] It is understandable that when the rear of a vehicle is subjected to a strong impact, the crushing and deformation of the crash box 3 can absorb a portion of the impact, thereby improving protection for the user. However, when a trailer is towing the vehicle from the rear, the crash box is easily deformed and may even tear during towing.

[0061] In the present invention, reinforcing plates 4 are provided on the outer periphery of crash box 3, allowing them and the crash box 3 to jointly withstand the pulling and impact forces from the trailer. This reduces deformation and tearing of crash box 3 when towing the vehicle, thereby improving the reliability of the vehicle when being towed. Furthermore, this prevents crash box 3 from collapsing and deforming even after minor impacts, raising the threshold for collapse and deformation of crash box 3. This reduces the frequency of replacement and repair of crash box 3, thereby reducing maintenance costs.

[0062] Among them, in the present invention, the reinforcing plate 4 is provided on the lower side of the crash box 3. However, the present invention is not limited thereto, and the reinforcing plate 4 can also be provided on the upper side, left side or right side of the crash box 3.

[0063] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, multiple reinforcement plates 4 are spaced apart along the circumference of the crash box 3. It should be noted that the crash box 3 extends in the front-to-back direction, and the direction surrounding the outer peripheral wall of the crash box 3 is the circumferential direction of the crash box 3. This further reduces deformation and tearing of the crash box 3 when towing the vehicle, thereby improving the reliability of the vehicle when being towed.

[0064] For example, Figure 6 and Figure 7 In the example shown, there are two reinforcing plates 4 spaced apart along the circumferential direction of the energy absorption box 3 , but the present invention is not limited thereto. The number of reinforcing plates 4 may also be other numbers, such as 3, 4, 5 or 6.

[0065] In some embodiments of the present invention, Figure 4 and Figure 6-Figure 8 As shown, the energy absorption box 3 has a third cavity 31, and the third cavity 31 penetrates the energy absorption box 3 along the length direction of the energy absorption box 3. The third cavity 31 has at least one third reinforcing rib 32, and the third reinforcing rib 32 divides the third cavity 31 into multiple third sub-cavities 311, and each third sub-cavity 311 penetrates the energy absorption box 3 along the length direction of the energy absorption box 3.

[0066] It should be noted that the second reinforcing ribs 22 extend along the length direction of the crash box 3 , thereby facilitating the division of the third cavity 31 into a plurality of third sub-cavities 311 penetrating the crash box 3 along the length direction.

[0067] It is understood that the provision of the third cavity 31 reduces the weight of the crash box 3 and improves its energy absorption performance. Furthermore, the provision of multiple third sub-cavities 311 allows the crash box 3 to effectively isolate vibration and noise, enhancing NVH (Noise, Vibration, and Harshness) performance. The provision of at least one third reinforcing rib 32 within the third cavity 31 further enhances the structural strength of the crash box 3, thereby further reducing deformation and tearing of the crash box 3 when towing a vehicle, thereby improving the vehicle's reliability when being towed.

[0068] For example, Figure 3 and Figure 4 In the example shown, there are two third reinforcing ribs 32, and the two third reinforcing ribs 32 are arranged perpendicular to each other, and there are four third sub-cavities 311, but the present invention is not limited to this. The first reinforcing ribs 12 can be other numbers, and the first sub-cavities 111 can also be other numbers. For example, the first reinforcing ribs 12 can be 1, 3, 5 or 6, etc., and the first sub-cavities 111 can be 2, 3, 6 or 7, etc.

[0069] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 5 As shown, the energy absorbing boxes 3 are multiple and spaced apart along the length direction of the rear anti-collision beam body 1. Therefore, when the rear of the vehicle is hit hard, the multiple energy absorbing boxes 3 collapse and deform to further absorb the impact, thereby further improving the protection of the user.

[0070] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the rear anti-collision beam assembly 10 also includes: a connecting column 5, one end of the connecting column 5 is passed through the rear anti-collision beam body 1 and connected to the rear anti-collision beam body 1, and the other end of the connecting column 5 extends into the energy absorption box 3 and is connected to the energy absorption box 3.

[0071] It can be understood that the provision of the connecting column 5 further improves the structural strength of the energy absorption box 3, thereby further reducing the deformation and tearing of the energy absorption box 3 when towing the vehicle, thereby improving the reliability of the vehicle when towed by a trailer.

[0072] Furthermore, if Figure 7 and Figure 8 As shown, the connecting column 5 has a threaded hole 51 therein, so that the trailer can be connected to the vehicle through threaded fasteners, so that the trailer can be detachably connected to the vehicle, thereby improving the portability when towing the trailer.

[0073] Furthermore, the connecting column 5 and the energy absorption box 3 are an integrated part, which simplifies the process, reduces the assembly and welding steps, increases the structural strength, shortens the production cycle and can effectively reduce the production cost in mass production compared with the traditional trailer threaded pipe welding structure.

[0074] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 5 As shown, the energy absorbing box 3 and the energy absorbing member 2 are spaced apart in the longitudinal direction of the rear anti-collision beam body 1; it can be understood that since the energy absorbing member 2 is spaced apart in the longitudinal direction of the rear anti-collision beam body 1, the structure of the rear anti-collision beam assembly 10 where the energy absorbing member 2 is not provided is relatively weak. However, by arranging the energy absorbing box 3 and the energy absorbing member 2 in the longitudinal direction of the rear anti-collision beam body 1 at intervals, the energy absorbing box 3 can be provided between some adjacent energy absorbing members 2, thereby improving the structural strength and energy absorption effect of the rear anti-collision beam assembly 10, and improving the protection of the vehicle and the user.

[0075] In some embodiments of the present invention, the energy absorption box 3 and the rear longitudinal beam of the vehicle are arranged opposite to each other in the front-rear direction of the vehicle.

[0076] In some embodiments of the present invention, the energy absorbing member 2 is an aluminum member; it is understandable that aluminum has a low material density, which is beneficial for optimizing the weight of the energy absorbing member 2 and contributing to the lightweighting of the vehicle. At the same time, the rear anti-collision beam body 1 is also an aluminum member, which is beneficial for optimizing the weight of the rear anti-collision beam body 1 and contributing to the lightweighting of the vehicle. In addition, the rear anti-collision beam body 1 and the energy absorbing member 2 are made of the same material, which improves the connection performance between the rear anti-collision beam body 1 and the energy absorbing member 2, and further enables the rear anti-collision beam body 1 and the energy absorbing member 2 to better jointly withstand the impact force, thereby further improving the structural strength of the rear anti-collision beam assembly 10 and improving the protective effect of the vehicle.

[0077] In some embodiments of the present invention, the energy absorbing member 2 is connected to the rear anti-collision beam body 1 by welding or riveting. This improves the connection reliability between the energy absorbing member 2 and the rear anti-collision beam body 1, allowing the rear anti-collision beam body 1 and the energy absorbing member 2 to better jointly withstand the impact force, thereby further improving the structural strength of the rear anti-collision beam assembly 10 and enhancing the protective effect of the vehicle.

[0078] A vehicle according to an embodiment of the present invention will be described below.

[0079] The vehicle according to the embodiment of the present invention includes the aforementioned rear anti-collision beam assembly 10 .
