Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a side panel rear section assembly and a vehicle. Background Art

[0002] As part of the vehicle body frame, the structure of the rear section of the side panel assembly has a great impact on the strength of the D-pillar assembly, vehicle weight, vehicle collision stiffness, body accuracy, vehicle safety, and pedestrian protection.

[0003] In the existing side panel rear section assembly, the side panel rear section is connected to the rear bumper mounting plate along the vehicle Y direction. The thickness of the rear bumper mounting plate is relatively thin. When the vehicle collides from the side and rear, the crumple space of the rear bumper is insufficient. The collision force is directly transmitted through the rear bumper mounting plate to the side panel outer panel connected to the side panel rear section, resulting in an increased risk of damage to the rear bumper mounting plate, the side panel outer panel and other rear body components, severe deformation of the body D-pillar, and further severe deformation of the luggage compartment, causing injuries to passengers and affecting the safety performance of the entire vehicle. The increased risk of damage to the rear body components also increases the maintenance and repair costs of the entire vehicle.

[0004] In addition, in the existing side panel rear section assembly, the side panel rear section and the side panel outer panel are an integral part. If the step depth of the side panel rear section is increased to increase the collapse space of the rear bumper, this part will crack during molding and cannot be molded. The side panel rear section assembly is not only for installing the rear bumper, but also for installing the rear taillights. The Z-direction installation space and precision requirements for this area are extremely high. If the existing integrated side panel rear section assembly solution is to form a large side wall depth, the side wall draft angle must be increased, which will result in insufficient Z-direction installation space for the vehicle, affecting the installation of the rear taillights and resulting in poor vehicle body precision. Utility Model Content

[0005] The utility model aims to at least solve the technical problems existing in the prior art, such as insufficient crumple space for the rear bumper, easy damage to the rear part of the vehicle body, affecting the safety performance of the entire vehicle, and difficulty in molding the rear section assembly of the side panel, affecting the installation of the rear taillights and the accuracy of the entire vehicle body.

[0006] In order to solve the above technical problems, the utility model provides, on the one hand, a side panel rear section assembly, including a side panel outer panel, a side panel outer panel rear section and a rear section extension plate, wherein the bottom of the side panel outer panel is connected to one end of the side panel outer panel rear section, the other end of the side panel outer panel rear section extends toward the front of the vehicle and is connected to one end of the rear section extension plate, the other end of the rear section extension plate extends toward the front of the vehicle and is connected to the D-pillar inner panel, and the rear section extension plate has a step portion that decreases step by step in a stepped manner.

[0007] In some embodiments, the step portion includes a first side panel portion, a first transverse panel portion, and a second side panel portion connected in sequence, the top of the first side panel portion is connected to the rear section of the side panel outer panel, and the second side panel portion is connected to the D-pillar inner panel.

[0008] In some embodiments, a first energy absorption cavity is formed between the first side panel portion and the D-pillar inner panel; and a collapse space is formed on the side of the first transverse panel portion and the first side panel portion toward the side outer panel.

[0009] In some embodiments, the bottom of the side outer panel is provided with a first connecting flange bent toward the inside thereof, and the first connecting flange is connected to the rear section of the side outer panel in upper and lower parts.

[0010] In some embodiments, the other end of the rear section of the side outer panel is provided with a second connecting flange bent downward, and the second connecting flange is connected to the first side panel portion.

[0011] In some embodiments, the bottom of the side outer panel is also connected to the rear bumper, and the collapse distance between the rear bumper and the second side panel portion is greater than or equal to 170 mm.

[0012] In some embodiments, a connection between the rear section of the side outer panel and the first side panel portion forms a first crush induction point, and a connection between the first side panel portion and the first transverse panel portion forms a second crush induction point.

[0013] In some embodiments, the first transverse plate portion is an inclined plate or a horizontal plate, and the first side plate portion and the second side plate portion are vertical plates or inclined plates.

[0014] In some embodiments, a taillight mounting plate extension plate is further connected between the top of the D-pillar inner panel and the top of the side panel outer panel, and the taillight mounting plate extension plate has a bending portion to form a third crush induction point.

[0015] Another aspect of the utility model provides a vehicle, comprising the above-mentioned side panel rear section assembly.

[0016] The side panel rear section assembly and the vehicle provided by the embodiment of the utility model are configured as a split structure, comprising a side panel outer panel, a side panel outer panel rear section and a rear section extension panel, wherein the bottom of the side panel outer panel is connected to one end of the side panel outer panel rear section, the other end of the side panel outer panel rear section extends toward the front of the vehicle and is connected to one end of the rear section extension panel, the other end of the rear section extension panel extends toward the front of the vehicle and is connected to the D-pillar inner panel, the rear section extension panel has a step portion that decreases step by step in a step-like manner, and can be installed on the side panel. The larger energy-absorbing cavity enclosed between the side panel rear section assembly and the D-pillar inner panel forms a larger crumple space between the D-pillar inner panel and the rear bumper, effectively protecting the D-pillar assembly and other body frame structures, improving the safety performance and pedestrian protection level of the whole vehicle, and reducing the repair and maintenance costs of the whole vehicle; in addition, the split side panel rear section assembly is easy to process and form, which solves the problem that the energy-absorbing buffer part of the existing integral side panel rear section assembly cannot be formed due to the deep forming depth, and can provide sufficient Z-direction installation space for installing the rear taillights, thereby ensuring the body accuracy of the whole vehicle.

[0031] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0032] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0033] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present invention.

[0034] Figures 1 to 6 The figure shows a schematic diagram of the structure of the side panel rear section assembly provided by the embodiment of the utility model. Figures 1 to 6 As shown, the first embodiment of the utility model provides a side panel rear section assembly 10, including a side panel outer panel 1, a side panel outer panel rear section 2 and a rear section extension plate 3, the bottom of the side panel outer panel 1 is connected to one end of the side panel outer panel rear section 2, the other end of the side panel outer panel rear section 2 extends toward the front of the vehicle and is connected to one end of the rear section extension plate 3, the other end of the rear section extension plate 3 extends toward the front of the vehicle and is connected to the D-pillar inner panel 20, and the rear section extension plate 3 has a step portion 31 that decreases step by step in a stepped manner.

[0035] Specifically, the side panel rear section assembly 10 is located on the left and right sides of the rear bumper 30. After the rear bumper 30 is subjected to a side collision, the collision force can be transmitted to the D-pillar inner plate 20 and other components on the inner side of the vehicle body through the side panel rear section assembly 10, and then transmitted to the passenger compartment. The side collision force includes the X-direction collision force and the Y-direction collision force.

[0036] Among them, the X direction refers to the front and rear direction of the vehicle (the direction in which the vehicle body moves forward or backward), that is, the length direction of the vehicle body; the Y direction refers to the left and right direction of the vehicle, that is, the width direction of the vehicle body; the Z direction refers to the up and down direction of the vehicle, that is, the height direction of the vehicle body.

[0037] The side outer panel 1 is arranged vertically at the rear of the vehicle, the side outer panel rear section 2 is arranged transversely at the front side of the side outer panel 1 and connected to one end of the rear section extension plate 3, and the rear section extension plate 3 is arranged transversely at the front side of the side outer panel rear section 2 and connected to the D-pillar inner panel 20 in front of it. The side outer panel 1, the side outer panel rear section 2, the rear section extension plate 3 and the D-pillar inner panel 20 enclose an energy absorption cavity, which can absorb the collision force transmitted by the side outer panel 1.

[0038] The step portion 31 that gradually decreases in a stepped manner allows the rear extension plate 3 to extend downward in the direction of the vehicle body height and connect with the bottom of the D-pillar inner panel 20, thereby increasing the vertical distance of the rear extension plate 3 in the Y direction of the vehicle, forming a larger first energy absorption cavity 41 between the D-pillar inner panel 20 and the step portion 31, thereby increasing the energy absorption space in the Y direction between the D-pillar inner panel 20 and the side panel rear section assembly 10, and cooperating with the second energy absorption cavity 42 between the D-pillar inner panel 20 and the side panel outer panel 1, which can effectively absorb the collision force transmitted to the D-pillar inner panel 20 through the side panel outer panel 1.

[0039] When a large collision occurs at the side and rear of the vehicle, the rear bumper 30 serves as a primary energy absorption component, the side panel rear section assembly 10 serves as a secondary energy absorption component, and the D-pillar assembly (including the D-pillar inner panel 20) serves as a tertiary energy absorption component. The larger energy absorption cavity (including the above-mentioned first energy absorption cavity 41 and second energy absorption cavity 42) enclosed by the side panel rear section assembly 10 and the D-pillar inner panel 20 can increase the secondary energy absorption space, effectively protect the D-pillar assembly and other body frame structures, thereby improving the safety performance of the entire vehicle and the pedestrian protection level, and effectively solving the problem of severe deformation of the body D-pillar during a side and rear collision, resulting in severe deformation of the luggage compartment and high injury value to passengers.

[0040] The rear bumper 30 is arranged vertically at the bottom of the side outer panel 1. Through the transversely arranged side outer panel rear section 2 and rear section extension plate 3, and the step portion 31 arranged on the rear section extension plate 3, the distance between the rear section extension plate 3 and the rear bumper 30 can be increased. This distance is the crushing distance of the rear bumper 30 (the crushing distance when the rear end of the vehicle body comes into rigid contact with an external object), which increases the safety distance during a low-speed collision and improves the pedestrian protection performance. The transversely arranged side outer panel rear section 2 and rear section extension plate 3 and the step portion 31 increase the crushing space of the rear bumper 30. The collision force of the rear bumper 30 can be effectively absorbed through the crushing space, reducing the risk of damage to the vehicle body sheet metal parts such as the bumper mounting bracket during a low-speed collision, thereby reducing the risk of secondary damage to the vehicle (most of the collision force is absorbed by the rear bumper 30 and the crushing space), improving the safety factor of the entire vehicle, and at the same time, reducing the repair and maintenance costs of the entire vehicle.

[0041] like Figure 5 As shown, the crumple space includes a primary crumple space 51 and a secondary crumple space 52. The primary crumple space 51 refers to the space between the rear bumper 30 and one end of the rear section 2 of the side outer panel away from the side outer panel 1, and the secondary crumple space 52 refers to the space between one end of the rear section extension plate 3 away from the D-pillar inner panel 20 and the D-pillar inner panel 20.

[0042] In this embodiment, the lateral (along the vehicle X-direction) extension length of the rear section 2 of the side outer panel and the rear extension plate 3 can be set and the size of the step portion 31 can be adjusted according to actual needs to change the spatial sizes of the first energy absorption cavity 41, the second energy absorption cavity 42, the primary crumple space 51 and the secondary crumple space 52.

[0043] The step portion 31 can also strengthen and solidify the side outer panel rear section 2 and the side outer panel 1 area, improve the overall structural strength of the side outer panel rear section assembly 10, achieve high-strength load-bearing, and improve the collision stiffness of the entire vehicle. At the same time, the side of the step portion 31 facing the side outer panel 1 (or the rear bumper 30) can weaken and guide the collision energy, guide the collision energy to the secondary crumple space 52, achieve secondary energy absorption, and achieve step-by-step weakening of the collision force and step-by-step reduction of the energy. With the high-strength load-bearing function of the step portion 31, the problem of severe deformation of the D-pillar of the vehicle body during a side and rear collision of the vehicle body can be solved.

[0044] In addition, the side panel rear section assembly 10 is configured as a split structure, and the three components of the side panel outer panel 1, the side panel outer panel rear section 2 and the rear section extension plate 3 are processed and formed separately, which is convenient for processing and forming. It solves the problem that the energy absorption and buffering part of the side panel rear section assembly 10 cannot be formed due to the deep forming depth caused by the formability factors of sheet metal and other parts, and can provide sufficient Z-direction installation space to install the rear taillights, thereby ensuring the body accuracy of the entire vehicle.

[0045] In some embodiments, Figures 2 to 6 As shown, the step portion 31 includes a first side panel portion 311 , a first transverse panel portion 312 and a second side panel portion 313 connected in sequence, the top of the first side panel portion 311 is connected to the rear section 2 of the side panel outer panel, and the second side panel portion 313 is connected to the D-pillar inner panel 20 .

[0046] The rear extension plate 3 first extends downward through the first side panel portion 311, then extends toward the front of the vehicle through the first transverse panel portion 312, and then extends downward through the second side panel portion 313 and is closely connected with the D-pillar inner panel 20. The vertical height of the Y-direction energy absorption space is increased by the first side panel portion 311, the crushing distance of the rear bumper 30 is increased by the first transverse panel portion 312, the connection strength with the D-pillar inner panel 20 is ensured by the second side panel portion 313, and the collision force is dispersed by the second side panel portion 313.

[0047] The second side plate portion 313 and the D-pillar inner plate 20 are fitted and connected to increase the connection area between the two and ensure the reliability of the connection between the two. The second side plate portion 313 and the D-pillar inner plate 20 can be fitted and welded, or they can be fixed and connected by fasteners after fitting. A reinforcing plate can be provided between the second side plate portion 313 and the D-pillar inner plate 20 as needed to improve the overall structural strength of the side rear section assembly 10.

[0048] A first energy absorption cavity 41 is formed between the first side panel portion 311 and the D-pillar inner panel 20 , that is, the first side panel portion 311 , the first transverse panel portion 312 and the D-pillar inner panel 20 enclose the first energy absorption cavity 41 , thereby increasing the energy absorption space in the Y direction between the D-pillar inner panel 20 and the side panel rear section assembly 10 .

[0049] A primary collapse space 51 is formed between the first side plate portion 311 (and its extension line) and the rear bumper 30 , and a secondary collapse space 52 is formed on the side of the first transverse plate portion 312 and the second side plate portion 313 facing the rear bumper 30 (or the side outer panel 1 ).

[0050] In this embodiment, the first transverse plate portion 312 is an inclined plate, which can form a larger energy absorption space (or energy absorption cavity) between the D-pillar inner plate 20 and the rear extension plate 3. The first transverse plate portion 312 can also be a horizontal plate. The first side plate portion 311 and the second side plate portion 313 are vertical plates or inclined plates, and the shape of the second side plate portion 313 matches the shape of the lower part of the D-pillar inner plate 20, so that the two are reliably connected, the connection strength of the two is improved, and the D-pillar is prevented from being severely deformed.

[0051] The D-pillar inner panel 20 can be made of thick high-strength steel plate, which can effectively improve the strength of the D-pillar inner panel 20. When the collision force is transmitted to the D-pillar inner panel 20, the impact force can be effectively weakened, the deformation resistance of the vehicle body outer covering can be improved, and the vehicle body firmware can be protected from deformation when the vehicle collides at a low speed.

[0052] In the above embodiment, the first transverse plate portion 312 is provided between the first side plate portion 311 and the second side plate portion 313 to form a single step. In a specific implementation, multiple steps that gradually decrease can be provided between the first side plate portion 311 and the second side plate portion 313 to form multiple force transmission paths and multiple energy absorption spaces between the rear extension plate 3 and the D-pillar inner plate 20, and multiple crush spaces are formed outside the rear extension plate 3 (toward the side of the rear bumper 30), so that the collision force is gradually weakened and the collision energy is gradually reduced through long-distance crushing and energy absorption.

[0053] In some other embodiments, the step portion 31 includes a second transverse plate portion, a first side plate portion 311, a first transverse plate portion 312, and a second side plate portion 313 connected in sequence, that is, the side enclosure outer panel rear section 2 can be overlapped and connected with the second transverse plate portion, and then the second transverse plate portion is connected with the first side plate portion 311, so that two steps can be formed, which can also increase the energy absorption space between the D-pillar inner panel 20 and the side enclosure rear section assembly 10, and increase the collapse space between the side enclosure outer panel rear section 2, the rear section extension plate 3, and the rear bumper 30. In this embodiment, the rear section extension plate 3 adopts a single-step step, which can reduce the weight of the entire vehicle.

[0054] In some embodiments, Figure 5As shown, the bottom of the side outer panel 1 is provided with a first connecting flange 11 bent toward the inside thereof, and the first connecting flange 11 is connected to the side outer panel rear section 2 up and down. By providing the first connecting flange 11 on the side outer panel 1, it is convenient to connect with the side outer panel rear section 2, and the first connecting flange 11 can be welded with the side outer panel rear section 2. The side outer panel rear section 2 can be processed and formed by a front drawing process, and the side outer panel rear section 2 is easy to form, which solves the problem that the integral side rear section assembly 10 structure cannot be formed due to the large forming depth. At the same time, the space of the side rear section assembly 10 in the Z direction of the vehicle is increased, which is convenient for installing components such as rear taillights and ensuring the accuracy of the vehicle body. The thickness and plate model of the side outer panel rear section 2 can be set according to different collision levels to meet the different safety performance requirements of the vehicle.

[0055] In some embodiments, Figures 3 to 5 As shown, the other end of the side outer panel rear section 2 is provided with a second connecting flange 21 bent downward, and the second connecting flange 21 is connected to the first side plate portion 311. Similar to the above-mentioned first connecting flange 11, the downward second connecting flange 21 facilitates the connection between the side outer panel rear section 2 and the first side plate portion 311 of the rear section extension plate 3, and the second connecting flange 21 and the first side plate portion 311 are welded along the vehicle X direction and / or Y direction, so that the side outer panel rear section 2 and the rear section extension plate 3 can be reliably connected.

[0056] The split side panel rear section assembly 10 reduces the difficulty of developing and processing the side panel rear section assembly 10 , and can meet the development and processing requirements of the side panel rear section assembly 10 for different vehicle models with a shorter development cycle and lower development costs.

[0057] In some embodiments, the collapse distance between the rear bumper 30 and the second side plate portion 313 is greater than or equal to 170 mm.

[0058] The second side panel 313 is closely connected to the D-pillar inner panel 20 . The distance L between the second side panel 313 and the rear bumper 30 is the crush distance of the rear bumper 30 . The crush distance is greater than or equal to 170 mm, which can effectively prevent the D-pillar from being deformed in collision.

[0059] Furthermore, a first collapse distance L1 of the primary collapse space 51 is greater than or equal to 110 mm, and a second collapse distance L2 of the secondary collapse space 52 is greater than or equal to 60 mm, wherein L=L1+L2.

[0060] In some embodiments, Figure 5As shown, the connection between the rear section 2 of the side outer panel and the first side panel portion 311 forms a first crush induction point 61, and the connection between the first side panel portion 311 and the first transverse panel portion 312 forms a second crush induction point 62. When the vehicle is subjected to a side collision, the first crush induction point 61 and the second crush induction point 62 can effectively guide the collision energy to the air space area, realize long-distance crush energy absorption, and improve the collision stiffness of the whole vehicle.

[0061] In some embodiments, Figure 5 As shown, a taillight mounting plate extension plate 40 is also connected between the top of the D-pillar inner panel 20 and the top of the side panel 1, and the taillight mounting plate extension plate 40 has a bending portion 401 to form a third crush induction point 402. The bending portion 401 can extend the force transmission path and increase the effective energy absorption of the air separation area (the bending portion 401 area); at the same time, the collision force borne by the top of the side panel 1 can be guided to the top of the D-pillar inner panel 20 through the third crush induction point 402 of the bending portion 401, and the collision force borne by the side panel 1 can be guided to different positions of the D-pillar inner panel 20 through different force transmission paths in conjunction with the first crush induction point 61 and the second crush induction point 62, so as to achieve effective dispersion of the collision force and avoid serious deformation of the vehicle body D-pillar. The bending portion 401 is preferably a V-shaped structure.

[0062] The second embodiment of the utility model provides a vehicle including the above-mentioned side panel rear section assembly 10. The vehicle corresponds to the side panel rear section assembly 10 of the above-mentioned embodiment. Any optional items in the embodiment of the side panel rear section assembly 10 are also applicable to the embodiment of the vehicle and will not be described in detail here.
