Rear panel assembly of automobile, vehicle, and installation method of rear panel assembly of automobile.

[0001] This application claims priority to Chinese Patent Application No. 202510107085.1, filed on January 23, 2025, entitled "Automobile Rear Assembly, Vehicle and Method for Installing Automobile Rear Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of automotive technology, and in particular to an automotive rear assembly, a vehicle, and a method for installing the automotive rear assembly. Background Technology

[0003] The torsional stiffness of a car body reflects its ability to resist deformation. The rear panel is an important component of the car's frame, and its torsional stiffness directly affects the torsional stiffness of the car body. However, when the rear panel assembly connects to the rear floor, it is often done through the connection between the inner and outer panels. This results in a smaller cross-section for the rear panel assembly when the rear longitudinal beam height is low, leading to lower torsional stiffness and failing to meet the torsional stiffness requirements of the car body.

[0012] In one possible implementation, the main body further has a second transition section, through which the first end of the first mounting section is connected to the first connecting flange, such that the first connecting flange is parallel to the first mounting section.

[0013] In one possible implementation, the rear panel assembly further includes a reinforcing member located within a first cavity structure.

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0033] In the first aspect, this embodiment relates to a rear panel assembly of an automobile. Figure 1 shows a structural schematic diagram of the inner rear panel assembly 1, Figure 2 shows a structural schematic diagram of the outer rear panel assembly 2, Figure 3 shows a cross-sectional structural schematic diagram of the rear panel assembly of the automobile, Figure 4 shows a cross-sectional structural schematic diagram of the inner rear panel assembly 1, Figure 5 shows a cross-sectional structural schematic diagram of the outer rear panel assembly 2, and Figure 6 shows a structural schematic diagram of the reinforcing member 6.

[0034] Referring to Figure 1 and in conjunction with Figures 2 and 3, the automotive rear panel assembly includes an inner rear panel assembly 1 and a first outer rear panel assembly 2. The inner rear panel assembly 1 includes a first connecting portion 12, a main body portion 11, and a second connecting portion 13 connected sequentially. The main body portion 11 is adapted to connect to the rear floor 3 of the vehicle. For example, the rear side of the rear floor 3 may have a connecting sheet metal 31, which can be fixedly connected to the main body portion 11 via a third connecting portion 311. Here, "rear side" refers to the rearmost side of the vehicle, while "front side" is the forwardmost side of the vehicle, opposite to the rearmost side.

[0035] The first rear outer panel assembly 2 is located on the rear side of the rear inner panel assembly 1, and the first end of the first rear outer panel assembly 2 is connected to the first connecting part 12, and the second end of the first rear outer panel assembly 2 is connected to the second connecting part 13, so that the first connecting part 12, the main body part 11, the second connecting part 13 and the first rear outer panel assembly 2 are enclosed to form the first cavity structure 4.

[0036] In order to form the first cavity structure 4, the two ends of the main body 11 can be connected to the first connecting part 12 and the second connecting part 13 extending toward the first rear outer panel assembly 2 to form a C-shape. The first connecting part 12 overlaps with the first end of the first rear outer panel assembly 2, and the second connecting part 13 overlaps with the second end of the first rear outer panel assembly 2, so that the first rear outer panel assembly 2 and the main body 11 can form an open-shaped first cavity structure 4.

[0037] The middle part of the first rear outer panel assembly 2 can be recessed to the side away from the main body 11 to form a C shape. The first connecting part 12, the main body 11 and the second connecting part 13 can be connected in sequence to form a flat plate. The first end of the first rear outer panel assembly 2 overlaps with the first connecting part 12 and the second end of the first rear outer panel assembly 2 overlaps with the second connecting part 13, so that a first cavity structure 4 is formed between the first rear outer panel assembly 2 and the main body 11.

[0038] The two ends of the main body 11 can be connected to the first connecting part 12 and the second connecting part 13 extending toward the first rear outer panel assembly 2 to form a C shape, and the middle part of the first rear outer panel assembly 2 can be recessed toward the side away from the main body 11 to form a C shape. The first end of the first rear outer panel assembly 2 overlaps with the first connecting part 12, and the second end of the first rear outer panel assembly 2 overlaps with the second connecting part 13, so that a first cavity structure 4 is formed between the first rear outer panel assembly 2 and the main body 11.

[0039] In this way, the rear inner panel assembly 1 and the first rear outer panel assembly 2 can withstand external pressure. At the same time, the first cavity structure 4 formed by the first connecting part 12, the main body part 11, the second connecting part 13 and the first rear outer panel assembly 2 can improve the torsional stiffness of the automobile rear assembly.

[0040] Referring again to Figure 1, in the prior art, the fourth connecting part 81 at the first end of the second rear outer panel assembly 8 is fixedly connected to the main body part 11 and the third connecting part 311 at the same location, and the second end of the second rear outer panel assembly 8 is fixedly connected to the second connecting part 13, thereby forming a second cavity structure enclosed by the second rear outer panel assembly 8, the first connecting part 12, the main body part 11 and the second connecting part 13.

[0041] In this embodiment, the rear inner panel assembly 1 is connected to the first end and the second end of the first rear outer panel assembly 2 via the first connecting part 12 and the second connecting part 13, respectively, and is connected to the rear floor 3 via the main body part 11 located between the first connecting part 12 and the second connecting part 13. Thus, with a fixed height of the rear longitudinal beam in the Z direction, the Z-direction distance between the first end and the second end of the first rear outer panel assembly 2 is greater than the Z-direction distance between the first end and the second end of the second rear outer panel assembly 8. This allows the first cavity structure 4, formed by the first connecting part 12, the main body part 11, the second connecting part 13, and the first rear outer panel assembly 2, to have a larger cross-section than the second cavity structure, thereby improving the torsional stiffness of the vehicle's rear assembly.

[0042] It should be noted that the Z-axis is the height direction of the vehicle.

[0043] In one example, the rear inner panel assembly 1 can be formed by stamping from sheet metal.

[0044] In one example, the first rear outer panel assembly 2 can be formed by stamping metal sheet.

[0045] In one example, referring to FIG4, the main body 11 has a first mounting section 111 and a first reinforcing section 112. The first mounting section 111 is adapted to be connected to the rear floor 3. For example, the first mounting section 111 is fixedly connected to the rear floor 3 by a third connecting part 311 of the connecting sheet metal 31.

[0046] Furthermore, the first end of the first mounting segment 111 is connected to the first connecting portion 12, and the second end of the first mounting segment 111 is connected to the first end of the first reinforcing segment 112. The second end of the first reinforcing segment 112 is bent towards the rear and connected to the second connecting portion 13. The first included angle 51 formed by the first reinforcing segment 112 and the first mounting segment 111 is an obtuse angle. For example, the first included angle 51 can be 150°, 160°, or 155°, etc.

[0047] For example, the rear inner panel assembly 1 may be formed by sequentially connecting the first connecting part 12, the first mounting section 111, the first reinforcing section 112, and the second connecting part 13.

[0048] Since the main body 11 is connected to the rear floor 3 through the first mounting section 111 and the first reinforcing section 112 bends toward the rear, the rigidity of the main body 11 can be improved on the one hand, and since the first angle 51 formed by the first reinforcing section 112 and the first mounting section 111 is an obtuse angle, the stress performance of the main body 11 can be improved. When the vehicle is subjected to a rear impact or rear pressure, the possible deformation is reduced, and the safety of the vehicle in the event of a car accident is improved.

[0049] It also helps to increase the cross-sectional size of the first cavity structure 4, thereby further improving the torsional stiffness of the rear assembly of the automobile.

[0050] In one example, continuing to refer to FIG4, the main body 11 further includes a second reinforcing section 113. The first end of the second reinforcing section 113 is connected to the second end of the first reinforcing section 112, and the second end extends rearward and connects to the second connecting portion 13. The second included angle 52 formed by the second reinforcing section 113 and the first reinforcing section 112 is an obtuse angle; for example, the second included angle 52 can be 150°, 160°, or 155°, etc. Furthermore, the second reinforcing section 113 is perpendicular to the first mounting section 111.

[0051] For example, the rear inner panel assembly 1 may be formed by sequentially connecting the first connecting part 12, the first mounting section 111, the second reinforcing section 113, the first reinforcing section 112, and the second connecting part 13.

[0052] Since the second reinforcing section 113 extends rearward from the second end of the first reinforcing section 112, it is beneficial to further increase the cross-sectional size of the first cavity structure 4.

[0053] Meanwhile, since both the first included angle 51 and the second included angle 52 are obtuse angles, and the second reinforcing section 113 is perpendicular to the first mounting section 111, the stress performance of the main body 11 can be further improved, and it has stronger resistance to deformation, thereby improving the torsional stiffness of the rear assembly of the automobile.

[0054] In one example, continuing to refer to FIG4, the main body 11 also has a first transition section 114, the first end of the second reinforcing section 113 is connected to the second end of the first reinforcing section 112 through the first transition section 114, and the first transition section 114 is recessed toward the first cavity structure 4.

[0055] For example, the rear inner panel assembly 1 may be formed by sequentially connecting the first connecting part 12, the first mounting section 111, the second reinforcing section 113, the first reinforcing section 112, the first transition section 114, and the second connecting part 13.

[0056] Since the first transition section 114 of the recessed structure connects the second reinforcing section 113 and the first reinforcing section 112, the stiffness of the connection between the second reinforcing section 113 and the first reinforcing section 112 can be improved. At the same time, since the first transition section 114 is recessed towards the first cavity structure 4, it is beneficial to improve the stress performance of the main body 11 when resisting pressure from the rear, improve the deformation resistance of the main body 11 in the event of a car accident, and improve the safety of the vehicle.

[0057] In one example, continuing to refer to Figure 4, the first connecting portion 12 is a first connecting flange, and the main body 11 also has a second transition section 115. The first end of the first mounting section 111 is connected to the first connecting portion 12 through the second transition section 115, making the first connecting flange parallel to the first mounting section 111. Thus, the presence of the second transition section 115 can improve the rigidity of the first mounting section 111 and the first connecting flange, and since the first connecting flange is parallel to the first mounting section 111, it is beneficial to improve the overall planar rigidity between the first mounting section 111 and the first connecting flange, thereby improving the torsional rigidity of the rear assembly of the vehicle.

[0058] In one example, continuing to refer to Figure 1, the first connecting part 12 is a first connecting flange, the second connecting part 13 is a second connecting flange, the first end of the first rear outer panel assembly 2 has a third connecting flange 21, and the second end has a fourth connecting flange 22. The first connecting flange and the third connecting flange 21 are attached to each other and connected, and the second connecting flange and the fourth connecting flange 22 are attached to each other and connected.

[0059] In this way, since the first connecting flange and the third connecting flange 21 are attached to each other and connected, and the second connecting flange and the fourth connecting flange 22 are attached to each other and connected, it is beneficial to transfer the pressure borne by the rear inner panel assembly 1 to the first rear outer panel assembly 2, or the pressure borne by the first rear outer panel assembly 2 to the rear inner panel assembly 1. This allows the rear inner panel assembly 1 and the first rear outer panel assembly 2 to jointly bear the pressure borne by either of them, thereby improving the force transmission performance between the rear inner panel assembly 1 and the first rear outer panel assembly 2, and thus improving the torsional stiffness of the automobile rear panel assembly.

[0060] In one example, referring to Figure 6 and in conjunction with Figure 2, the rear panel assembly further includes a reinforcing member 6 located within the first cavity structure 4. The reinforcing member 6 has a first fitting portion 61, a support portion 62, and a second fitting portion 63. The first fitting portion 61 is fitted and connected to the main body portion 11, and the second fitting portion 63 is fitted and connected to the first rear panel assembly 2. The first end of the support portion 62 is connected to the first fitting portion 61, and the second end is connected to the second fitting portion 63.

[0061] In this way, when the main body 11 is subjected to external force, the force can be transmitted to the first rear outer panel assembly 2 through the support part 62 and the second fitting part 63 via the first fitting part 61. Since the first fitting part 61 is fitted with the main body 11 and the second fitting part 63 is fitted with the first rear outer panel assembly 2, the force can be dispersed to a certain extent, thereby further improving the force transmission performance between the first rear outer panel assembly 2 and the main body 11.

[0062] When the first rear outer panel assembly 2 is subjected to external force, the force can be transmitted to the first rear outer panel assembly 2 through the second fitting part 63, the support part 62 and the first fitting part 61. Since the first fitting part 61 is fitted with the main body part 11 and the second fitting part 63 is fitted with the first rear outer panel assembly 2, the force can be dispersed to a certain extent, thereby further improving the force transmission performance between the first rear outer panel assembly 2 and the main body part 11.

[0063] Thus, the reinforcing member 6 is located inside the first cavity structure 4, which can improve the structural stiffness and torsional deformation resistance of the cavity structure 4, and help the rear inner panel assembly 1 and the first rear outer panel assembly 2 resist deformation that may be caused by external pressure.

[0064] In one example, the reinforcement 6 can be formed by stamping a sheet metal.

[0065] In one example, as shown in Figure 2 and in conjunction with Figure 6, the reinforcing member 6 can be located in the middle of the first cavity structure 4 and is in a U-shape. Each of the support portion 62 and the second fitting portion 63 includes two parts. One side of the first fitting portion 61 is fitted to the main body portion 11. The first ends of the two support portions 62 are respectively connected to the two ends of the first fitting portion 61, and the second ends extend toward the first rear outer panel assembly 2 and are respectively connected to the two second fitting portions 63 extending along the first rear outer panel assembly 2.

[0066] In this way, the second fitting part 63 has a larger fitting area with the main body part 11. When the first rear outer panel assembly 2 is subjected to external force and the force is transmitted to the main body part 11, it can better prevent the main body part 11 from deforming, thereby helping to maintain the stability of the vehicle's interior space.

[0067] In one example, referring to Figure 5, the main body 11 has a first mounting section 111, which is adapted to be fixedly connected to the rear floor 3 via a first connecting edge 311. The first rear outer panel assembly 2 has a second mounting section 23 and a third reinforcing section 24. The first end of the second mounting section 23 is connected to the second connecting portion 13, and the second end is connected to the first end of the third reinforcing section 24. The second end of the third reinforcing section 24 is bent forward and connected to the first connecting portion 12. The third included angle 53 formed between the third reinforcing section 24 and the second mounting section 23 can be an obtuse angle. For example, the third included angle 53 can be 150°, 160°, 155°, etc.

[0068] For example, the first rear outer panel assembly 2 can be formed by sequentially connecting the third connecting flange 21, the third reinforcing section 24, the second mounting section 23 and the fourth connecting flange 22, thereby giving the first rear outer panel assembly 2 strong rigidity.

[0069] The second mounting section 23 is parallel to the first mounting section 111, the first fitting part 61 is at least fitted and connected to the first mounting section 111, and the second fitting part 63 is at least fitted and connected to the second mounting section 23.

[0070] For example, as shown in Figure 5 and with reference to Figure 6, the first fitting part 61 can be fitted with the main body part 11, and the second fitting part 63 can include a first fitting flange 631 and a second fitting flange 632. The first fitting flange 631 can be fitted and connected with the second mounting section 23, and the second fitting flange 632 can be fitted and connected with the third reinforcing section 24.

[0071] In one example, both the first fitting flange 631 and the second mounting section 23 may have corresponding first mounting holes 6311. The vehicle rear assembly also includes a first fastener, which may be rod-shaped. The rod-shaped first fastener passes sequentially through the first mounting holes 6311 of the first fitting flange 631 and the first mounting holes 6311 of the second mounting section 23. Thus, the first fitting flange 631 and the second mounting section 23 are fixedly connected together by the second fastener 32.

[0072] In one example, the first fastener may be a bolt. For instance, the nut at the first end of the bolt abuts against the second mounting section 23, and the second end of the bolt passes sequentially through the first mounting hole 6311 of the second mounting section 23 and the first mounting hole 6311 of the first fitting flange 631. The nut is then screwed onto the second end of the bolt and abuts against the first fitting flange 631. Thus, the first fitting flange 631 is fixedly connected to the second mounting section 23 by the bolt and the nut.

[0073] In another example, the first fastener can be a pin. For instance, the first end of the pin has a pin cap that abuts against the second mounting section 23, and the second end of the pin passes sequentially through the first mounting hole 6311 of the second mounting section 23 and the first mounting hole 6311 of the first fitting flange 631, and is riveted to the first fitting flange 631. Thus, the first fitting flange 631 is fixedly connected to the second mounting section 23 by the pin.

[0074] In another example, the first fastener may be a screw. For example, the first end of the screw has a screw cap that abuts against the second mounting section 23, and the second end of the screw passes through the first mounting hole 6311 of the second mounting section 23 and is screwed into the first mounting hole 6311 of the first fitting flange 631, wherein the first mounting hole 6311 of the first fitting flange 631 is a screw hole.

[0075] Since the second mounting section 23 is parallel to the first mounting section 111, and the first fitting part 61 fits with the first mounting section 111 and the second fitting part 63 fits with the second mounting section 23, the resistance of the reinforcing member 6 to pressure from the rear side can be improved, thereby further improving the structural strength and torsional stiffness of the rear panel assembly of the vehicle.

[0076] In one example, the connection between the first fitting flange 631 and the second mounting section 23, as well as the connection between the second fitting flange 632 and the third reinforcing section 24, can be fixedly connected by welding or SPR riveting. This improves the stability of the connections between the first fitting flange 631 and the second mounting section 23, and between the second fitting flange 632 and the third reinforcing section 24, preventing shaking or impacts that could cause abnormal noises, and thus improving the vehicle's NVH (Noise, Vibration, Harshness) performance.

[0077] In one example, before the first fitting flange 631 and the second mounting section 23 and the second fitting flange 632 can be welded or SPR riveted to the third reinforcing section 24, the first fitting flange 631 and the second mounting section 23 can be pre-positioned by the first fastener, thereby improving the connection efficiency and accuracy between the first fitting flange 631 and the second mounting section 23 and the second fitting flange 632 and the third reinforcing section 24.

[0078] In one example, the first fitting portion 61 and the first mounting section 111 can be connected by adhesive. For example, by applying damping adhesive between the first fitting portion 61 and the first mounting section 111 to fix the first fitting portion 61 and the first mounting section 111, it is beneficial to improve the NVH performance of the vehicle.

[0079] In one example, both the first fitting portion 61 and the first mounting section 111 have a third mounting hole 612. The rear panel assembly also includes a third fastener, which may be rod-shaped. The rod-shaped third fastener passes sequentially through the third mounting hole 612 of the first fitting portion 61 and the third mounting hole 612 of the first mounting section 111. Thus, the first fitting portion 61 and the first mounting section 111 can be fixedly connected together by the third fastener. For example, the third fastener may be a bolt.

[0080] In one example, the first connecting flange and the third connecting flange 21, as well as the second connecting flange and the fourth connecting flange 22, can be fixedly connected by welding or SPR riveting.

[0081] In one example, the first fitting portion 61 further has an extension 611 extending between the first connecting flange and the third connecting flange 21, such that the extension 611 is clamped between the first connecting flange and the third connecting flange 21. This improves the stability of the connection between the reinforcing member 6 and the rear inner panel assembly 1 and the first rear outer panel assembly 2.

[0082] In one example, depending on the material of the rear floor 3, the body of the rear floor 3 and the connecting sheet metal 31 can be integrally formed or they can be independent structural parts that are fixedly connected together by bolts, screws or other means.

[0083] For example, as shown in Figure 1, the connecting sheet metal 31 and the body of the rear floor 3 can be fixedly connected together by the second fastener 32. The connecting sheet metal 31 can be L-shaped, and both the body of the rear floor 3 and the first side of the connecting sheet metal 31 have second mounting holes. The second fastener 32 can be rod-shaped, and the rod-shaped second fastener 32 passes sequentially through the second mounting holes of the rear floor 3 and the connecting sheet metal 31, thereby fixing the connecting sheet metal 31 and the body of the rear floor 3 together by the second fastener 32. For example, the second fastener 32 can be a bolt, nut, pin, or screw.

[0084] In one example, the rear bumper assembly also includes multiple rear bumper mounting brackets 7. For instance, the rear bumper mounting brackets 7 may include three, five, or four as shown in Figure 3. The rear bumper can be mounted using the rear bumper mounting brackets 7.

[0085] In this embodiment, the rear inner panel assembly 1 is connected to the first end and the second end of the first rear outer panel assembly 2 via the first connecting part 12 and the second connecting part 13, respectively, and is connected to the rear floor 3 via the main body part 11 located between the first connecting part 12 and the second connecting part 13. With a fixed height of the rear longitudinal beam in the Z direction, the Z-direction distance between the first end and the second end of the first rear outer panel assembly 2 is large, thereby enabling the first cavity structure 4 formed by the first connecting part 12, the main body part 11, the second connecting part 13 and the first rear outer panel assembly 2 to have a large cross section, thereby improving the torsional stiffness of the automobile rear panel assembly.

[0086] Secondly, this embodiment also provides a vehicle that includes a rear-mounted vehicle assembly as described in any of the first aspects.

[0087] The vehicle in this embodiment uses the rear axle assembly of this application and has all the beneficial technical effects of the embodiments of the first aspect of this application.

[0088] Thirdly, this embodiment also provides a method for installing a vehicle rear panel assembly. The method for installing a vehicle rear panel assembly as described in the first aspect includes the following steps:

[0089] First step: Connect the main body 11 of the rear inner panel assembly 1 to the rear floor 3. For example, the first connecting edge 311 of the main body 11 and the rear floor 3 can be fixedly connected together by welding or SPR riveting.

[0090] The second step involves connecting the first end of the first rear outer panel assembly 2 to the first connecting part 12, and connecting the second end of the first rear outer panel assembly 2 to the second connecting part 13, so that the first connecting part 12, the main body 11, the second connecting part 13, and the first rear outer panel assembly 2 enclose each other to form the first cavity structure 4. For example, the first end of the first rear outer panel assembly 2 and the first connecting part 12, as well as the second end of the first rear outer panel assembly 2 and the second connecting part 13, can be fixedly connected together by welding or SPR riveting.

[0091] In one example, the rear panel assembly further includes a reinforcing member 6 located within the first cavity structure 4. The reinforcing member 6 has a first fitting portion 61, a support portion 62, and a second fitting portion 63. The first fitting portion 61 is fitted and connected to the main body portion 11, and the second fitting portion 63 is fitted and connected to the first rear panel assembly 2. The first end of the support portion 62 is connected to the first fitting portion 61, and the second end is connected to the second fitting portion 63. The installation method of the rear panel assembly further includes a third step, located between the first and third steps, in which the second fitting portion 63 is fixedly connected to the first rear panel assembly 2. Furthermore, the second step also includes fitting and connecting the main body portion 11 to the first fitting portion 61.

[0092] The method for installing the rear panel assembly of a car in this embodiment is used to install the rear panel assembly of the car of this application, and the resulting rear panel assembly of the car has all the beneficial technical effects of the embodiments of the first aspect of this application.

[0093] Furthermore, the installation method of the rear panel assembly of the automobile first connects the inner rear panel assembly 1 to the rear floor 3, and then connects the first end of the first outer rear panel assembly 2 to the first connecting part 12 and the second end to the second connecting part 13. This facilitates the connection of the inner rear panel assembly 1 and the first outer rear panel assembly 2 by means of resistance welding or SPR riveting, thereby improving the torsional stiffness of the automobile rear panel assembly.
