Description

Technical Field

[0001] This utility model belongs to the field of vehicle structure design technology, specifically relating to a vehicle rear skirt assembly, a vehicle rear structure, and a vehicle. Background Technology

[0002] The rear skirt assembly typically includes components such as an outer rear skirt panel, an inner rear skirt panel, pillar inner panels, and possibly localized reinforcing plates, and is an important part of the vehicle's rear structure. Usually, the rear skirt assembly is welded to the vehicle body as a single unit. In traditional rear skirt assembly structures, the outer rear skirt panel is generally designed to be relatively wide, with the inner rear skirt panel and pillar inner panels overlapping it. The lower edge of the outer rear skirt panel then connects to the rear floor.

[0003] In related technologies, to improve the overall vehicle weight reduction, the rear skirt outer panel needs to be thinned. However, because the rear skirt outer panel is relatively wide, the thinned rear skirt outer panel is prone to problems such as springback and deformation, affecting the precision of the parts and thus the production quality of the rear skirt assembly. In addition, the strength near the connection between the thinned rear skirt outer panel and the rear floor is weakened, which cannot meet the requirements for vehicle stability.

[0004] Therefore, it is necessary to improve the design of the existing rear skirt assembly in order to meet the production quality requirements of the rear skirt assembly after the outer panel of the rear skirt is thinned, and to meet the requirements of vehicle body stability. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a vehicle rear skirt assembly, a vehicle rear structure, and a vehicle, which can facilitate the production quality requirements of the rear skirt assembly after the rear skirt outer panel is thinned, and can facilitate the requirements of vehicle body stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle rear skirt assembly, comprising an inner rear skirt panel and an inner pillar panel and an outer rear skirt panel respectively fixed to the inner rear skirt panel, wherein the inner rear skirt panel is provided with a first body connecting section extending downward and beyond the lower edge of the outer rear skirt panel, the first body connecting section being used to connect with a designated part of the vehicle body structure.

[0007] Furthermore, the inner panel of the pillar is at least partially overlapped and fixed to the inner panel of the rear skirt, and the inner panel of the pillar is provided with a second body connecting section extending downward and beyond the lower edge of the outer panel of the rear skirt. The second body connecting section is used to connect with a designated part of the body structure.

[0008] Furthermore, the two ends of the outer tail skirt panel along its length are respectively fixedly connected to the inner panel of the column.

[0009] Furthermore, the lower edge of the first body connecting section is provided with an elongated protrusion that protrudes inward toward the vehicle interior. The side of the elongated protrusion facing inward toward the vehicle interior in the protrusion direction is flat and is used to connect with the rear floor of the body structure.

[0010] Furthermore, the first vehicle body connecting section is provided with multiple vertically arranged vertical reinforcing ribs, and the lower part of the vertical reinforcing ribs extends downward to the elongated protrusion.

[0011] Furthermore, the second body connecting section is provided with at least one transverse reinforcing rib arranged laterally along the body.

[0012] Furthermore, it also includes a back latch eye reinforcement plate disposed between the inner and outer panels of the tail skirt, and the back latch eye reinforcement plate and the inner panel of the tail skirt form a reinforcement cavity with an approximately triangular cross section; the back latch eye reinforcement plate is provided with at least one reinforcement connecting lug, and the reinforcement connecting lug is fixedly connected to the inner panel of the tail skirt.

[0013] A vehicle rear structure includes a rear skirt assembly as described above, and a rear floor, the rear portion of which is fixedly connected to the pillar inner panel and the rear skirt inner panel, respectively.

[0014] Furthermore, it also includes a rear section of a rear longitudinal beam, the rear part of which is fixedly connected to the inner plate of the column; a side panel connecting plate for connecting to the side panel assembly is fixedly provided on the side of the rear section of the rear longitudinal beam away from the rear floor, the rear part of which is fixedly connected to the inner plate of the column.

[0015] A vehicle including the rear structure as described above.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The vehicle rear skirt assembly, rear structure, and vehicle provided by this utility model can facilitate meeting the production quality requirements of the rear skirt assembly after the outer panel of the rear skirt is thinned, and can also meet the requirements of vehicle body stability. Specifically, in this vehicle rear skirt assembly structure, a first body connecting section extending downward and beyond the lower edge of the outer panel of the rear skirt, provided on the inner panel of the rear skirt, can be used to connect with the vehicle body structure, thus eliminating the need for connection through the outer panel of the rear skirt. In other words, the width of the outer panel of the rear skirt can be shortened during design, which reduces problems such as springback and deformation of the thinner outer panel, thereby improving the production quality of the rear skirt assembly. Furthermore, since the connection with the vehicle body structure can be achieved through the first body connecting section on the inner panel of the rear skirt, the inner panel is relatively thicker than the outer panel, and is unaffected by the narrowing of the outer panel, ensuring the stability requirements of the vehicle body connection.

Detailed Implementation

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0026] Please see Figure 1-5This embodiment discloses a vehicle rear skirt assembly, including an inner rear skirt panel 1 and pillar inner panels 2 and an outer rear skirt panel 3 respectively fixed to the inner rear skirt panel 1. The inner rear skirt panel 1 has a first body connecting section 101 extending downward and beyond the lower edge of the outer rear skirt panel 2. The first body connecting section 101 is used to connect with a designated part of the vehicle body structure. It is understood that the outer rear skirt panel 3 is fixed to the outside of the inner rear skirt panel 1, with the side of the inner rear skirt panel 1 closest to the rear of the vehicle being its outside. The pillar inner panels 2 on both sides of the vehicle's lateral direction are respectively fixed to the lateral sides of the inner rear skirt panel 1. The outer rear skirt panel 3 and the pillar inner panels 2 are generally fixed to the inner rear skirt panel 1 by welding. After the outer rear skirt panel 3 is connected to the inner rear skirt panel 1, a cavity reinforcement structure is usually formed between them. The pillar inner panel 2 can be a D-pillar inner panel or a C-pillar inner panel, adapted according to the specific vehicle model. In this embodiment, the pillar inner panel 2 is a D-pillar inner panel. The first body connecting section 101 and the inner rear skirt panel 1 adopt an integral molding structure. Understandably, similar to the connection between the rear skirt assembly and the body of existing vehicles, the body setting here usually refers to the rear floor and / or rear longitudinal beams, etc.

[0027] The aforementioned rear skirt assembly structure facilitates meeting the production quality requirements of the rear skirt assembly after the outer rear skirt panel 3 is thinned, and also meets the requirements for vehicle body stability. Specifically, in this rear skirt assembly structure, a first body connecting section 101 extending downwards and beyond the lower edge of the outer rear skirt panel 3 on the inner rear skirt panel 1 can be used to connect to the vehicle body structure, eliminating the need for connection via the outer rear skirt panel 3. That is, during design, the Z-direction (vehicle height direction) width of the outer rear skirt panel 3 can be shortened. This reduces the likelihood of springback and deformation in the thinner outer rear skirt panel 3, thereby improving the production quality of the rear skirt assembly. Furthermore, since the connection to the vehicle body structure is achieved through the first body connecting section 101 on the inner rear skirt panel 1, the inner rear skirt panel 1, being thicker than the outer rear skirt panel 2, is unaffected by the narrowing of the outer rear skirt panel 3, thus ensuring the stability of the vehicle body connection. In addition, the beneficial effect of the rear skirt assembly of this vehicle is that, since the outer panel 3 of the rear skirt can be thinned and narrowed as a whole, the weight of the extended part of the inner panel 1 of the rear skirt is much less than the weight of the reduced part of the outer panel 3 of the rear skirt, which can help improve the lightweight design of the vehicle.

[0028] In this embodiment, the inner pillar plate 2 is at least partially overlapped and fixed to the inner rear skirt plate 1, and the inner pillar plate 2 is provided with a second body connecting section 201 extending downward and beyond the lower edge of the outer rear skirt plate 1. The second body connecting section 201 is used to connect with a designated part of the vehicle body structure. It is understood that, similar to the connection between the rear skirt assembly and the vehicle body in existing vehicles, the designated part of the vehicle body here typically refers to the rear floor and / or rear longitudinal beams, etc. Specifically, the inner pillar plate 2 is fixed to the inner surface of the inner rear skirt plate 1 by lap welding. The second body connecting section 201 and the inner pillar plate 2 are integrally formed structures. It is understood that inner pillar plates 2 are provided on both sides of the length direction (corresponding to the width direction of the vehicle) of the inner rear skirt plate 1. By overlapping and fixing the inner pillar plate 2 to the inner rear skirt plate 1, the connection strength of the connection points between the two is ensured. Meanwhile, the second body connecting section 201 provided on the inner pillar panel 2 allows for connection with the body structure during assembly, thereby further enhancing the reliability of the connection between the rear skirt assembly and the body structure and better meeting the requirements for vehicle stability. Since the inner pillar panel 2 needs to overlap with the side panel assembly, the second body connecting section 201 also strengthens the connection between the lower part of the inner pillar panel 2 and the connection point with the side panel assembly. It is understandable that, because the inner pillar panel 2 overlaps on both sides of the rear skirt panel 1 along its length, the overall length of the rear skirt panel 1 is shorter than that of the outer rear skirt panel 3, and the rear skirt panel 1 is relatively thicker. Although this widens the rear skirt panel 1, it is less prone to deformation, springback, and other quality issues, ensuring the production quality of the rear skirt panel 1.

[0029] In this embodiment, the two ends of the rear skirt outer panel 3 along its length are fixedly connected to the pillar inner panel 2. After the rear skirt outer panel 3 is assembled into the vehicle, its length corresponds to the width of the vehicle body. Specifically, the two ends of the rear skirt outer panel 3 are welded and fixed to the corresponding pillar inner panel 2. By extending the rear skirt outer panel 3 and fixing it to the pillar inner panel 2, the structural strength of the rear part of the pillar inner panel 2 is enhanced, thereby enhancing the structural strength near the connection between the pillar inner panel 2 and the side panel assembly, and better ensuring the stability of the vehicle body structure.

[0030] In this embodiment, the lower edge of the first body connecting section 101 is provided with an elongated protrusion 101a that protrudes inward toward the vehicle interior. The side of the elongated protrusion 101a facing inward in the protrusion direction is flat and used to connect with the rear floor 4 of the body structure. Here, the length direction of the elongated protrusion 101a is arranged along the length direction of the rear skirt inner panel 1. It can be understood that the length direction of the elongated protrusion 101a is the width direction of the body. During final assembly, the top surface of the elongated protrusion 101a is attached to and welded to the flange on the rear floor 4. By setting the elongated protrusion 101a and making the top surface of the elongated protrusion 101a flat in the protrusion direction, it is beneficial to achieve a smooth docking with the rear floor 4, further ensuring the connection reliability of the connection part; at the same time, it is beneficial to improve the docking accuracy and reduce the processing accuracy requirements of the rear skirt inner panel 1.

[0031] In this embodiment, the first body connecting section 101 is provided with multiple vertically arranged vertical reinforcing ribs 101b, and the lower part of each vertical reinforcing rib 101b extends downward to the elongated protrusion 101a. Specifically, the multiple vertical reinforcing ribs 101b are arranged at intervals along the length direction of the rear skirt inner panel 1. The vertical reinforcing ribs 101b can be concave or convex rib structures. By providing multiple vertical reinforcing ribs 101b and extending the lower part of each vertical reinforcing rib 101b to the elongated protrusion 101a, the structural strength of the first body connecting section 101 can be effectively enhanced, thereby better ensuring the connection stability between the vehicle rear skirt assembly and the body structure. Moreover, the vertical reinforcing ribs 101b have a simple structure, which is conducive to processing and cost control.

[0032] In this embodiment, the second body connecting section 201 is provided with at least one transverse reinforcing rib 201a arranged laterally along the body. Specifically, one transverse reinforcing rib 201a is provided on each of the two sides of the second body connecting section 201. By providing transverse reinforcing ribs 201a on the second body connecting section 201, the structural strength of the second body connecting section 201 can be enhanced, thereby better ensuring the connection stability between the second body connecting section 201 and the body structure. The transverse reinforcing rib 201a can be a concave or convex rib structure, which is simple in structure and facilitates processing and cost control. If necessary, the second body connecting section 201 can also be thickened to ensure the usage requirements of connection stability with the body structure.

[0033] In this embodiment, a back latch eye reinforcing plate 5 is also included, disposed between the inner rear skirt panel 1 and the outer rear skirt panel 3, and the back latch eye reinforcing plate 5 and the inner rear skirt panel 1 form a reinforcing cavity 5a with an approximately triangular cross-section; the back latch eye reinforcing plate 5 is provided with at least one reinforcing connecting lug 501, and the reinforcing connecting lug 501 is fixedly connected to the inner rear skirt panel 1. Specifically, the back latch eye reinforcing plate 5 is obliquely braced on the back of the inner rear skirt panel 1, and the upper and lower parts of the back latch eye reinforcing plate 5 are welded and fixed to the inner rear skirt panel 1, respectively. Here, "a reinforcing cavity 5a with an approximately triangular cross-section" means that the cross-section of the reinforcing cavity 5a in the longitudinal direction of the vehicle body is approximately triangular. "Approximately triangular" means that it is not a triangle in the strict standard sense. Here, there are two reinforcing connecting lugs 501, which are symmetrically arranged on the lateral sides of the upper part of the back latch eye reinforcing plate 5. By forming an approximately triangular reinforcing cavity 5a between the rear door latch eye reinforcing plate 5 and the tail skirt inner plate 1, and by setting a reinforcing connecting lug 501, the structural strength near the connection area between the rear door latch and the tail skirt inner plate is effectively enhanced, which can effectively reduce the risk of deformation in the latch installation area.

[0034] Furthermore, in this embodiment, to enhance the structural stability of the back latch eye reinforcement plate 5 and reduce the risk of deformation and failure, multiple reinforcing ribs 502 are provided in the middle of the back latch eye reinforcement plate 5 in the transverse direction. Reinforcing flanges 503 are respectively designed on the edges of both sides of the back latch eye reinforcement plate 5 in the transverse direction. By providing the designed reinforcing flanges 503, the torsional strength of the back latch eye reinforcement plate 5 is effectively improved. In this embodiment, a back latch eye nut plate 8 is also fixedly provided on the back latch eye reinforcement plate 5. Multiple connecting ear plates 801 are provided in the circumferential direction of the back latch eye nut plate 8. The connecting ear plates 801 fix the back latch eye reinforcement plate 5 to the back latch eye nut plate 8. By adding multiple connecting ear plates 801, the installation reliability of the back latch eye nut plate 8 is effectively improved. Through the above structural improvements, the strength of the components of the back latch eye reinforcement plate 5 and the strength of the tail skirt assembly are greatly enhanced, especially the strength of the back latch mounting surface, improving the deformation resistance of the back latch.

[0035] This embodiment also discloses a vehicle rear structure, including a rear skirt assembly and a rear floor 4 as described above. The rear portion of the rear floor 4 is fixedly connected to the pillar inner panel 2 and the rear skirt inner panel 1, respectively. Here, the rear portion of the rear floor 4 refers to the rear portion in the front-rear direction of the vehicle body. Specifically, the rear portion of the rear floor 4 is provided with an upwardly folded connecting flange, which is welded and fixed to the pillar inner panel 2 and the rear skirt inner panel 1. More specifically, the connecting flange is connected to an elongated protrusion 101a. By fixing the rear floor 4 to the pillar inner panel 2 and the rear skirt inner panel 1 respectively, the overall connection strength between the vehicle rear skirt assembly and the vehicle body structure is good, resulting in good stability in use.

[0036] In this embodiment, the rear structure of the vehicle also includes a rear longitudinal beam rear section 6, the rear of which is fixedly connected to the inner column plate 2. A side panel connecting plate 7 for connecting to the side panel assembly is fixedly provided on the side of the rear longitudinal beam rear section 6 away from the rear floor 4, and the rear of the side panel connecting plate 7 is fixedly connected to the inner column plate 2. Specifically, a connecting plate is fixed to the rear of the rear longitudinal beam rear section 6, and the rear longitudinal beam rear section 6 is welded or screwed to the inner column plate 2 via the connecting plate. Typically, there are two sets of rear longitudinal beam rear sections 6, with the rear floor 4 fixedly connected between the two sets. Correspondingly, there are also two sets of side panel connecting plates 7, each set positioned laterally on the outer side of the corresponding rear longitudinal beam rear section 6. The rear edge of the side panel connecting plate 7 is welded and fixed to the inner column plate 2. In this structural design, by setting up the side panel connecting plate 7 and connecting the rear section 6 of the rear longitudinal beam to the inner plate 2 of the pillar respectively, it is beneficial to disperse the transmission of collision force, thereby improving the stability of the vehicle body structure and reducing the risk of side panel assembly failure and deformation.

[0037] This embodiment also discloses a vehicle, including the rear structure as described above. This vehicle has good body structure stability and facilitates lightweight design of the entire vehicle.
