[0035] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0036] like Figure 1As shown, the rear side panel assembly includes a C-pillar inner panel 10, and the C-pillar inner panel 10 is provided with perforations, which may be avoidance holes 101 and positioning holes 102. The avoidance holes 101 are for a tool gun to pass through, so that the rear wheel cover 20 and the C-pillar inner panel 10 can be connected by a tool gun; the positioning holes 102 are for the positioning pins to be inserted to achieve the overall positioning of the rear side panel assembly. Among them, the tool gun can be an SPR gun and an FDS tightening gun, and the tool gun is used to connect the C-pillar inner reinforcement plate, the C-pillar outer reinforcement plate and the rear wheel cover casting of the rear wheel cover 20 through the Self-Piercing Rivet (self-piercing riveting) or Flow Drill Screw (rotary tapping riveting) process. For some models, the avoidance holes 101 and the positioning holes 102 are both located on the inner side of the vehicle, and away from the inner and outer dividing lines of the vehicle. The avoidance holes 101 and the positioning holes 102 will not affect the sealing of the vehicle.

[0037] For other models, the inner and outer dividing lines of the vehicle are different from those of the above-mentioned models, resulting in the avoidance hole 101 and the positioning hole 102 being located near the inner and outer dividing lines of the vehicle. If the above-mentioned C-pillar inner panel 10 is still used, the sealing of the vehicle will not meet the requirements. The current method is to redesign the C-pillar inner panel 10 to meet the sealing requirements of the vehicle. This results in different models being unable to share the same C-pillar inner panel 10, and different C-pillar inner panels need to be designed for different models. When the vehicle is specifically produced, it is necessary to configure molds for the production of different C-pillar inner panels, which will undoubtedly increase the cost of the rear side assembly. In addition, it is also necessary to consider the matching and debugging of different C-pillar inner panels with related components, which prolongs the development cycle of the entire vehicle.

[0038] In order to solve the above problems, the embodiments of the present disclosure provide a rear side panel assembly, which can realize the sharing of C-pillar inner panels on different models. Figures 2 to 8 As shown, the rear side panel assembly of the disclosed embodiment includes a C-pillar inner panel 1 and a sealing panel 2, which is stacked and connected to the C-pillar inner panel 1. The C-pillar inner panel 1 is provided with at least one through hole 11 extending along its thickness direction, and the sealing panel 2 blocks the through hole 11.

[0039] The C-pillar inner plate 1 is provided with at least one through hole 11 , which can be understood as: the C-pillar inner plate 1 is provided with only one through hole 11 ; or, the C-pillar inner plate 1 is provided with at least two through holes 11 .

[0040] The rear side panel assembly of the disclosed embodiment can meet the sealing requirements of the C-pillar inner panel 1 by providing a sealing plate 2 connected to the C-pillar inner panel 1 and using the sealing plate 2 to block the perforation 11, so that the C-pillar inner panel 1 can meet the sealing requirements, so that when the perforation 11 is located near the inner and outer dividing line of the vehicle, the sealing requirements of the vehicle can also be met, that is, the C-pillar inner panel 1 can be used for a vehicle model in which the perforation 11 is located near the inner and outer dividing line of the vehicle. For a vehicle model in which the perforation 11 is far away from the inner and outer dividing line of the vehicle, it is not necessary to block the perforation 11 of the C-pillar inner panel 1, that is, the sealing plate 2 is not used. In short, when the sealing plate 2 is connected to the C-pillar inner panel 1 and blocks the perforation 11, the C-pillar inner panel 1 is suitable for one of the vehicle models (for example, a vehicle model in which the perforation 11 is located near the inner and outer dividing line of the vehicle); when the sealing plate 2 is not used to block the perforation 11 of the C-pillar inner panel 1, the C-pillar inner panel 1 is suitable for another vehicle model (for example, a vehicle model in which the perforation 11 is far away from the inner and outer dividing line of the vehicle).

[0041] Thus, the C-pillar inner panel 1 can be used for different models, that is, different models can share the same C-pillar inner panel 1, thereby reducing the number of molds used to produce the C-pillar inner panel 1 and reducing the cost of the rear side panel assembly. In addition, matching and debugging problems in the production process caused by different C-pillar inner panels 1 can be avoided, thereby shortening the development cycle of the whole vehicle and improving the efficiency of co-production of different models.

[0042] In addition, when different models can share the same C-pillar inner panel 1, while reducing the number of molds, it can also reduce investments in other fixed hardware and equipment, as well as reduce the production space and number of production personnel of the vehicle, greatly improving the output efficiency per unit area and per unit equipment, and reducing the production cost of the vehicle.

[0043] Optionally, the thickness of the C-pillar inner panel 1 is greater than the thickness of the cover panel 2, or the thickness of the C-pillar inner panel 1 is less than the thickness of the cover panel 2. In other words, the thickness of the C-pillar inner panel 1 is different from the thickness of the cover panel 2.

[0044] By setting the thickness of the C-pillar inner panel 1 and the thickness of the cover panel 2 to be different, the thickness of the C-pillar inner panel 1 and the cover panel 2 can be designed separately according to needs, so as to reduce the amount of material of the rear side panel assembly and reduce the weight of the rear side panel assembly while ensuring the structural strength of the rear side panel assembly, which is beneficial to the lightweight design of the vehicle.

[0045] Of course, in other embodiments, the thickness of the C-pillar inner panel 1 may also be equal to the thickness of the cover panel 2 .

[0046] In some embodiments, Figure 3 , Figure 7 and Figure 8 As shown, at least one through hole 11 is an escape hole 111 for escaping a tool gun.

[0047] The tool gun may be an SPR gun or an FDS tightening gun. At least one through hole 11 is a bypass hole 111 for avoiding the tool gun, which can be understood as follows: when there is only one through hole 11, the through hole 11 is a bypass hole 111; when there are at least two through holes 11, only one through hole 11 may be a bypass hole 111, or at least two through holes 111 may be bypass holes 111.

[0048] It is understandable that when assembling the rear side panel assembly with other parts, it is necessary to connect the rear side panel assembly with other parts, for example, connecting the C-pillar inner reinforcement plate, the C-pillar outer reinforcement plate with the rear wheel housing casting. By providing the avoidance hole 111, a tool gun can pass through the avoidance hole 111, so as to adopt the Self-Piercing Rivet (self-piercing riveting) or FlowDrill Screw (rotary tapping riveting) process to achieve the connection between the rear side panel assembly and other parts.

[0049] As a result, bolt connections between the rear side panel assembly and other components are avoided, which not only saves the cost of components such as bolts and nuts, further reducing the cost of the vehicle; it also reduces production hours, further improving the production efficiency of the vehicle.

[0050] In some embodiments, Figure 3 , Figure 7 and Figure 8 As shown, at least one through hole 11 is a first positioning hole 112 for inserting the positioning pin 5. Figure 3 and Figure 6 As shown, the sealing plate 2 is provided with a first protrusion 21, which is protruded in the direction away from the C-pillar inner plate 1, and an avoidance cavity 211 is formed between the first protrusion 21 and the C-pillar inner plate 1, and the avoidance cavity 211 is connected to the first positioning hole 112 to avoid the positioning pin 5.

[0051] At least one through hole 11 is a first positioning hole 112, which can be understood as: when the number of the through hole 11 is only one, the through hole 11 is the first positioning hole 112; when the number of the through holes 11 is at least two, only one through hole 11 can be the first positioning hole 112, or at least two avoidance holes 111 can be the first positioning hole 112.

[0052] It is understandable that, for a vehicle model that does not need to use the cover plate 2, the problem of interference between the cover plate 2 and the positioning pin 5 can be avoided, and the positioning pin 5 can be inserted into the first positioning hole 112 to achieve positioning of the rear side panel assembly. However, for a vehicle model that needs to use the cover plate 2, the problem of interference between the cover plate 2 and the positioning pin 5 is likely to occur, and the cover plate 2 needs to be reasonably designed to ensure that the positioning pin 5 can be inserted into the first positioning hole 112.

[0053] The rear side panel assembly of the disclosed embodiment is provided with a first protrusion 21 protruding in a direction away from the C-pillar inner panel 1 on the cover plate 2, and an avoidance cavity 211 is formed between the first protrusion 21 and the C-pillar inner panel 1 to avoid interference between the positioning pin 5 and the cover plate 2, thereby ensuring the positioning of the rear side panel assembly during vehicle assembly.

[0054] In some embodiments, Figure 3 and Figure 6 As shown, the C-pillar inner plate 1 is provided with a second protrusion 12, and the second protrusion 12 is provided in a direction away from the cover plate 2. The first positioning hole 112 is provided in the second protrusion 12, and the first protrusion 21 and the second protrusion 12 form an avoidance cavity 211.

[0055] By providing a second protrusion 12 protruding in the direction away from the cover plate 2 on the C-pillar inner panel 1, the first protrusion 21 and the second protrusion 12 are used to enclose an avoidance cavity 211, so that the space of the avoidance cavity 211 is larger, thereby more effectively avoiding interference between the positioning pin 5 and the cover plate 2.

[0056] In some embodiments, Figure 3 and Figure 6 As shown, the C-pillar inner plate 1 includes a first connection surface 13, and the cover plate 2 includes a second connection surface 23, and the second connection surface 23 is in contact with the first connection surface 13. The first connection surface 13 and the second connection surface 23 are both annular, and the first connection surface 13 is arranged around the through hole 11.

[0057] By providing a first connecting surface 13 surrounding the through hole 11 on the C-pillar inner panel 1 and providing a second connecting surface 23 on the sealing plate 2, and utilizing the second connecting surface 23 to fit with the first connecting surface 13, the sealing area between the sealing plate 2 and the C-pillar inner panel 1 can be increased, thereby improving the reliability of the rear side panel assembly.

[0058] Alternatively, if Fig. 9 and Fig.10 As shown, the first connection surface 13 and the second connection surface 23 are welded via a plurality of first welding points 25 and a plurality of second welding points 26 , wherein the plurality of first welding points 25 and the plurality of second welding points 26 are arranged at intervals around the through hole 11 .

[0059] In some embodiments, Figure 1 , Figure 7 and Figure 8 As shown, the rear side panel assembly also includes a C-pillar outer reinforcement plate 3, which is connected to the C-pillar inner panel 1. The edge of the C-pillar inner panel 1 is provided with at least one notch 14, which is provided outside the edge of the C-pillar outer reinforcement plate 3, and the sealing plate 2 blocks the notch 14.

[0060] The edge of the C-pillar inner panel 1 is provided with at least one notch 14, which can be understood as: the edge of the C-pillar inner panel 1 is provided with only one notch 14; or, the edge of the C-pillar inner panel 1 is provided with at least two notches 14. Figure 7 and Figure 8 As shown, there are two notches 14 , and the two notches 14 are located on different sides of the through hole 11 .

[0061] It is known to those skilled in the art that, in addition to being connected to the C-pillar outer reinforcement plate 3, the C-pillar inner plate 1 also needs to be connected to the rear wheel housing 4, and the rear wheel housing 4 includes a rear wheel housing inner plate 41 and a rear wheel housing outer plate 42, which results in a four-layer connection at the C-pillar inner plate 1, that is, the C-pillar inner plate 1, the C-pillar outer reinforcement plate 3, the rear wheel housing inner plate 41 and the rear wheel housing outer plate 42 are stacked and connected. In order to ensure the connection strength, it is necessary to avoid the situation where the four layers of plates are connected, and the usual practice is to set a notch 14 on one of the plates, such as setting a notch 14 on the C-pillar inner plate 1. For some vehicle models, for example, a vehicle model where the notch 14 is located near the inner and outer dividing line of the vehicle, the setting of the notch 14 will affect the sealing of the C-pillar inner plate 1, resulting in the vehicle's sealing not meeting the requirements.

[0062] The rear side panel assembly of the disclosed embodiment can ensure the sealing of the C-pillar inner panel 1 and meet the sealing requirements of the vehicle by using the sealing plate 2 to block the notch 14. That is, the sealing plate 2 can not only block the perforation 11, but also block the notch 14, which can reduce the number of sealing plates 2, thereby reducing not only the design and development cost of the sealing plate 2, but also the maintenance cost of the sealing plate 2, further improving the production efficiency of the vehicle.

[0063] Of course, in other embodiments, the rear side panel assembly may also include a plurality of sealing panels 2 , wherein a portion of the sealing panels 2 is used to seal the through holes 11 , and another portion of the sealing panels 2 is used to seal the panel gaps 14 .

[0064] In some embodiments, Fig. 9 and Fig.10 As shown, the cover plate 2 includes an extension portion 24, which is arranged outside the edge of the C-pillar inner plate 1. The extension portion 24 is provided with a second positioning hole 241 for positioning and matching with the rear wheel cover 4.

[0065] The second positioning hole 241 is positioned and matched with the rear wheel housing outer panel 42 . For example, the rear wheel housing outer panel 42 is provided with a positioning column, which is inserted into the second positioning hole 241 and positioned and matched with the second positioning hole 241 .

[0066] When assembling the vehicle, the cover plate 2 can be connected to the C-pillar inner plate 1 first, and then the second positioning hole 241 can be used to realize the positioning between the rear side panel assembly and the rear wheel cover 4, and then the C-pillar inner plate 1 can be connected to the rear wheel cover 4. Fig. 9 and Fig.10 As shown, first, the sealing plate 2 is welded to the C-pillar inner plate 1 through the first welding point 25; then, the second positioning hole 241 is positioned and matched with the rear wheel cover 4; thereafter, the C-pillar inner plate 1, the rear wheel cover 4 and the sealing plate 2 are welded through the second welding point 26. Thus, while the sealing plate 2 is connected to the C-pillar inner plate 1, the connection between the rear side panel assembly and the rear wheel cover 4 can be achieved, further improving the production efficiency of the vehicle.

[0067] Alternatively, if Fig. 9 and Fig.10 As shown, both sides of the C-pillar inner panel 1 in the width direction are provided with extension portions 24 , and each extension portion 24 is provided with a second positioning hole 241 .

[0068] By providing extension portions 24 on both sides of the C-pillar inner panel 1 in the width direction and providing a second positioning hole 241 on each extension portion 24, the positioning reliability between the rear side panel assembly and the rear wheel cover 4 can be improved, thereby improving the assembly accuracy between the rear side panel assembly and the rear wheel cover 4 and improving the reliability of the vehicle.

[0069] Optionally, the outer periphery of the extension portion 24 is triangular, and the second positioning hole 241 is provided at a corner of the extension portion 24 .

[0070] By setting the extension portion 24 to be triangular, when the stability of the extension portion 24 is good, the amount of material of the extension portion 24 can be saved, and the weight and cost of the cover plate 2 can be reduced, thereby reducing the weight and cost of the vehicle.

[0071] Optionally, the C-pillar inner panel 1 includes an escape zone, the sealing plate 2 is arranged in the escape zone, and the escape zone encloses an escape space, and the escape space is used to escape the air spring of the suspension. That is, at least a part of the air spring of the suspension is installed in the area of ​​the C-pillar inner panel 1 where the sealing plate 2 is arranged, that is, the area of ​​the C-pillar inner panel 1 where the sealing plate 2 is arranged is the outer side of the vehicle. The sealing plate 2 can be used to construct the inner and outer boundary of the vehicle, for example, the edge of the sealing plate 2 away from the rear wheel housing inner panel 41 forms the inner and outer boundary of the vehicle.

[0072] An escape space is formed by enclosing an area where a sealing plate 2 is provided on the inner panel 1 of the C-pillar. The escape space is used to escape the air spring of the suspension, thereby ensuring that the air spring of the suspension has sufficient installation space, thereby facilitating the layout and installation of the suspension.

[0073] The vehicle of the disclosed embodiment includes the rear side panel assembly described in any of the above embodiments.

[0074] For the rear side panel assembly of the disclosed embodiment, for vehicles in which the through hole 11 of the C-pillar inner panel 1 does not need to be blocked by the sealing plate 2, the C-pillar inner panel 1 realizes the overall positioning of the rear side panel assembly through the first positioning hole 112; the avoidance hole 111 is provided to allow the SPR gun to pass through, thereby realizing the connection between the C-pillar inner reinforcement plate, the C-pillar outer reinforcement plate and the rear wheel cover casting; at this time, the inner and outer dividing line of the vehicle is constructed by the rear wheel cover outer panel 42 and the rear wheel cover inner panel 41.

[0075] like Figures 2 to 10 As shown, for the vehicle model that needs to use the sealing plate 2 to block the perforation 11 of the C-pillar inner panel 1, the sealing plate 2 is used to construct the inner and outer boundary of the vehicle, and the inner and outer boundary of the vehicle constructed by the original rear wheel housing outer panel 42 and the rear wheel housing inner panel 41 are connected together to avoid the leakage area inside and outside the vehicle. The first protrusion 21 is set on the sealing plate 2, so that the first positioning hole 112 is shared by two vehicle models; the second positioning hole 241 set on the sealing plate 2 is set outside the inner and outer boundary of the vehicle to avoid leakage problems.

[0076] Although the embodiments of the present disclosure have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present disclosure. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present disclosure.
