Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a side panel rear section assembly and a vehicle. Background Art

[0002] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles to travel more and more frequently.

[0003] In the related art, the side of the vehicle body near the rear door is easily deformed due to external force impact. Patent document "CN218400737 U" discloses a rear wheel cover assembly, a vehicle body and a car. Among them, the rear wheel cover assembly includes a rear wheel cover, a shock absorber mounting plate, a first reinforcement plate, a second reinforcement plate, a C-pillar and a D-pillar. Among them, the shock absorber mounting plate is installed on the rear wheel cover, one end of the first reinforcement plate is connected to the intersection of the shock absorber mounting plate and the rear wheel cover, and the other end is connected to the C-pillar; one end of the second reinforcement plate is connected to the intersection of the shock absorber mounting plate and the rear wheel cover, and the other end is connected to the D-pillar. In this way, in the height direction of the vehicle body, the shock absorber mounting plate, the first reinforcement plate and the second reinforcement plate form a Y-shaped force transmission structure, so that the road impact force on the bottom of the vehicle body can be transmitted to the C-pillar and the D-pillar, so that the road impact force can be prevented from accumulating on the rear wheel cover, thereby improving the strength of the side of the vehicle body.

[0004] The above solution strengthens the longitudinal impact resistance of the rear section of the side panel of the vehicle body. However, when the vehicle is subjected to the impact force in the front and rear directions, the above structure cannot effectively improve the stress condition of the rear section of the side panel of the vehicle body, making the rear section of the side panel of the vehicle body easily deformed due to the impact force in the front and rear directions.

[0036] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles for travel more and more frequently. As described in the background technology, in the related technology, the rear section of the body side is easily deformed due to the impact force in the front and rear directions.

[0037] Based on the above problems, the present application proposes a side panel rear section assembly and a vehicle. In the first aspect, the present application proposes a side panel rear section assembly 100. Figure 1 As shown, the side wall rear section assembly 100 includes a C-pillar inner panel 110, a rear wall inner panel 130 and a side wall inner panel 120. The rear wall inner panel 130 is located behind the C-pillar inner panel 110, and the side wall inner panel 120 is provided with a protruding structure 120a protruding inwardly, one end of the protruding structure 120a is connected to the rear wall inner panel 130, and the other end of the protruding structure 120a is connected to the C-pillar inner panel 110.

[0038] The side inner panel 120 is provided with a protruding structure 120a protruding inwardly, and the inward side refers to the side close to the interior space of the vehicle. In addition, the front (or front) and rear (or front) mentioned in this article are in reference to the vehicle, that is, the direction pointed by the front of the vehicle is the front, and the direction pointed by the rear of the vehicle is the rear.

[0039] In the present application, the side wall rear section assembly 100 includes a C-pillar inner panel 110, a rear wall inner panel 130 and a side wall inner panel 120. The C-pillar inner panel 110 is a supporting structure of the rear section of the vehicle body in the height direction of the vehicle 10, the rear wall inner panel 130 is a tailgate at the rear of the vehicle body, and the side wall inner panel 120 is a main structure of the side wall of the rear section of the vehicle body. The side wall inner panel 120 is provided with a protruding structure 120a protruding inward, one end of the protruding structure 120a is connected to the rear wall inner panel 130, and the other end is connected to the C-pillar inner panel 110. In this way, in the front-to-back direction of the vehicle, the protruding structure 120a constitutes the main force transmission structure of the side wall inner panel 120. When the vehicle is impacted by external force in the front-to-back direction, the protruding structure 120a of the side wall inner panel 120 can form a force transmission path between the C-pillar inner panel 110 and the rear wall inner panel 130, and the impact force will be dispersed to the C-pillar inner panel 110 or the rear wall inner panel 130. This helps reduce the probability of deformation of the side panel inner plate 120 due to external force impact in the front and rear directions, thereby helping reduce the probability of deformation of the side panel rear section assembly 100, and further helping to improve the stability and reliability of the vehicle body side panel.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the protrusion structure 120a includes a first protrusion 121 and a second protrusion 122, the first protrusion 121 has a first end 121a connected to the rear enclosure inner panel 130 and a second end 121b connected to the C-pillar inner panel 110, the second protrusion 122 has a third end 122a connected to the rear enclosure inner panel 130 and a fourth end 122b connected to the C-pillar inner panel 110, and the distance between the second end 121b and the fourth end 122b is greater than the distance between the first end 121a and the third end 122a.

[0041] In this embodiment, the protrusion structure 120a includes a first protrusion 121 and a second protrusion 122. That is, two force transmission paths are formed between the C-pillar inner plate 110 and the rear enclosure inner plate 130, which is conducive to further reducing the probability of deformation of the side enclosure inner plate 120 due to external force impact. Furthermore, the distance between the second end 121b of the first protrusion 121 and the fourth end 122b of the second protrusion 122 is small, while the distance between the first end 121a of the first protrusion 121 and the third end 122a of the second protrusion 122 is large. In this way, in the direction of the rear enclosure inner plate 130 pointing to the C-pillar inner plate 110, the first protrusion 121 and the second protrusion 122 gradually move away from each other, so as to avoid the impact force of the first protrusion 121 and the second protrusion 122 converging to the same place of the C-pillar inner plate 110. This helps reduce the probability of deformation of the side panel inner panel 120 due to external force impact in the front and rear directions, while reducing the probability of deformation of the C-pillar inner panel 110 due to excessively concentrated impact force, which in turn helps improve the reliability of the C-pillar inner panel 110.

[0042] In a specific embodiment, Figure 2 Shown and referenced Figure 1 The first protrusion 121 includes a first sub-segment 1211 and a second sub-segment 1212 connected to each other, the first sub-segment 1211 is connected to the rear enclosure inner panel 130, and the second sub-segment 1212 is connected to the C-pillar inner panel 110. The second protrusion 122 includes a third sub-segment 1221 and a fourth sub-segment 1222 connected to each other, the third sub-segment 1221 is connected to the rear enclosure inner panel 130, and the fourth sub-segment 1222 is connected to the C-pillar inner panel 110. The first sub-segment 1211 and the third sub-segment 1221 are connected to each other, and the second sub-segment 1212 and the fourth sub-segment 1222 are arranged at intervals.

[0043] With such arrangement, the first protrusion 121 and the second protrusion 122 form two "Y"-shaped force transmission paths. In this way, the impact forces of the first protrusion 121 and the second protrusion 122 can be prevented from converging at the same point of the C-pillar inner panel 110, thereby reducing the probability of deformation of the side panel inner panel 120 due to external force impact in the front and rear directions, and reducing the probability of deformation of the C-pillar inner panel 110 due to excessive concentration of impact force, thereby also helping to improve the reliability of the C-pillar inner panel 110.

[0044] In some embodiments, a groove 123 is formed between the first protrusion 121 and the second protrusion 122, and the shape of the longitudinal section of the groove 123 includes at least one of a triangle, a circular arc, a square, a trapezoid, and an elliptical arc. The longitudinal section shape of the groove 123 can be one or more of the above shapes. When there are multiple shapes, it indicates that the longitudinal section shapes of the groove 121 at different positions are different.

[0045] Alternatively, if Figure 2 and Figure 3a As shown, the longitudinal cross-section of the groove 123 between the first sub-segment 1211 and the third sub-segment 1221 is triangular. Figure 2 and Figure 3b As shown, the longitudinal cross-section of the groove 123 between the second sub-segment 1212 and the fourth sub-segment 1222 is a trapezoid.

[0046] In some embodiments, Figure 1 and Figure 2As shown, the side inner panel 120 is provided with a reinforcing portion 124 protruding inwardly, and the reinforcing portion 124 is provided near the C-pillar inner panel 110, and one end of the reinforcing portion 124 is connected to the first protrusion 121, and the other end is connected to the second protrusion 122. By providing the reinforcing portion 124, the first protrusion 121 and the second protrusion 122 can be connected to each other near the end of the C-pillar inner panel 110. In this way, on the one hand, it is beneficial to improve the strength and impact resistance of the side inner panel 120. On the other hand, it is also beneficial to increase the contact area between the first protrusion 121, the second protrusion 122 and the C-pillar inner panel 110, so that the impact force transmitted by the first protrusion 121 and the second protrusion 122 can be transmitted to the C-pillar inner panel 110 and the reinforcing portion 124 at the same time. In this way, it is also beneficial to reduce the probability of deformation of the C-pillar inner panel 110 due to excessive impact force, and further, it is also beneficial to improve the reliability of the C-pillar inner panel 110.

[0047] In a second aspect, the present application provides a vehicle 10. Figure 4 and Figure 5 As shown, the vehicle 10 includes a vehicle body 11 , and the vehicle body 11 includes the side panel rear section assembly 100 described in the first aspect.

[0048] The vehicle 10 of the present application uses the side panel rear end assembly 100 described in the first aspect. When the vehicle 10 is impacted by external forces in the front and rear directions, the protruding structure 120a of the side panel inner plate 120 can form a force transmission path between the C-pillar inner plate 110 and the rear panel inner plate 130, and the impact force will be dispersed to the C-pillar inner plate 110 or the rear panel inner plate 130. In this way, the probability of deformation of the side panel inner plate 120 due to external force impact is reduced, thereby reducing the probability of deformation of the side panel rear section assembly 100, and further improving the stability and reliability of the vehicle body side panel.

[0049] In some embodiments, Figures 4 to 6 As shown, the vehicle 10 further includes a tailgate 12, which is connected to the vehicle body 11. The tailgate 12 includes a door roof 12a, a door side panel 12b, and a door tail panel 12c. The door tail panel 12c is connected to one end of the door roof 12a along a first direction X, and the door side panel 12b is connected to an end of the door roof 12a along a second direction Y. The first direction X is the front-rear direction of the vehicle 10, and the second direction Y is perpendicular to the first direction X and the height direction of the vehicle 10. The height direction of the vehicle 10 is referred to as direction Z.

[0050] In this embodiment, the back door 12 of the vehicle 10 can be sealed with the side rear section assembly 100. For example, the back door 12 is movably connected to the top of the vehicle body 11, so that the back door 12 can move relative to the side rear section assembly 100, thereby achieving a sealed connection or separation between the back door 12 and the side rear section assembly 100. The top refers to the end close to the roof of the vehicle 10, and the rear end refers to the side close to the rear of the vehicle.

[0051] The structure of the back door 12 in this embodiment is different from that of the back door in the related art. Figure 4 and Figure 5 As shown, the back door 12 in the present application has a door roof 12a connected to the door tail plate 12c and door side panels 12b located on both sides of the door roof 12a in addition to the door tail plate 12c at the rear. In other words, this embodiment also incorporates a part of the body side panel structure, such as the D-pillar, the portion between the D-pillar and the C-pillar, etc., into the back door 12.

[0052] This arrangement makes the opening of the back door opening of the side panel rear section assembly 100 larger. When the back door 12 and the side panel rear section assembly 100 are separated from each other, the volume of the luggage compartment space at the rear of the vehicle and the size in the first direction X are larger, which is conducive to improving the application scenarios of the luggage compartment at the rear of the vehicle, and further conducive to improving the functional diversity of the vehicle 10.

[0053] Optionally, in some embodiments, the vehicle 10 further includes a lower back door, which is located below the rear back door 12, and is rotatably connected to the side panel rear section assembly 100 of the vehicle body 11. In this way, the lower back door can rotate relative to the side panel rear section assembly 100, thereby being combined with or separated from the side panel rear section assembly 100. When the lower back door and the rear back door 12 are both sealed and combined with the side panel rear section assembly 100, the rear space of the vehicle 10 is sealed.

[0054] Furthermore, if Figure 5 As shown, the top edge of the side panel inner panel 120 and the rear end edge of the C-pillar inner panel 110 together form an inner sealing edge L1 for sealing with the door side panel 12b, thus defining a sealing profile between the side panel inner panel 120, the C-pillar inner panel 110 and the door side panel 12b of the back door 12. Further, the side panel rear section assembly 100 further includes a rear wheel housing inner panel 140, the top of which is respectively connected to the bottom of the side panel inner panel 120 and the bottom of the C-pillar inner panel 110. Thus, a connection profile between the side panel inner panel 120, the C-pillar inner panel 110 and the rear wheel housing inner panel 140 is defined.

[0055] In a specific embodiment, Figure 1 and Figure 5As shown, the protrusion structure 120a of the side enclosure inner panel 120 includes a first protrusion 121 and a second protrusion 122. The first protrusion 121 has a first end 121a connected to the rear enclosure inner panel 130 and a second end 121b connected to the C-pillar inner panel 110. The second protrusion 122 has a third end 122a connected to the rear enclosure inner panel 130 and a fourth end 122b connected to the C-pillar inner panel 110. The distance between the second end 121b and the fourth end 122b is greater than the distance between the first end 121a and the third end 122a. In this way, two force transmission paths are formed between the C-pillar inner panel 110 and the rear enclosure inner panel 130, which is conducive to further reducing the probability of deformation of the side enclosure inner panel 120 due to the impact of external force in the front and rear directions, thereby helping to reduce the probability of deformation of the side enclosure rear section assembly 100. Furthermore, the distance between the second end 121b of the first protrusion 121 and the fourth end 122b of the second protrusion 122 is relatively small, while the distance between the first end 121a of the first protrusion 121 and the third end 122a of the second protrusion 122 is relatively large. In this way, in the direction from the rear inner panel 130 to the C-pillar inner panel 110, the first protrusion 121 and the second protrusion 122 gradually move away from each other, thereby preventing the impact forces of the first protrusion 121 and the second protrusion 122 from converging at the same point of the C-pillar inner panel 110. In this way, the probability of deformation of the C-pillar inner panel 110 due to excessive concentration of impact forces is reduced, thereby improving the reliability of the C-pillar inner panel 110. Furthermore, the top edge of the first protrusion 121 and the rear end edge of the C-pillar inner panel 110 jointly form an inner sealing edge L1 for sealing with the door side panel 12b. Furthermore, the top of the rear wheel housing inner panel 140 is respectively connected to the bottom of the second protrusion 122 and the bottom of the C-pillar inner panel 110. In other words, the extension profile of the bottom of the second protrusion 122 and the bottom of the C-pillar inner panel 110 along the first direction X is the same as the extension profile of the top of the rear wheel housing inner panel 140 along the first direction X. Such a configuration is conducive to improving the convenience of connecting the rear wheel housing inner panel 140 with the side inner panel 120 and the C-pillar inner panel 110.

[0056] In some embodiments, Figure 4 and Figure 5 As shown, the side panel rear section assembly 100 also includes a C-pillar outer panel 150 and a rear wheel housing outer panel 160. The rear end edge of the C-pillar outer panel 150 has a first edge 151 extending along a third direction N. The third direction N is set at an angle with the height direction Z of the vehicle 10. The top edge of the rear wheel housing outer panel 160 has a second edge 161 connected to the first edge 151. The second edge 161 extends along the first direction X. The first edge 151 and the second edge 161 together form an outer sealing edge L2 for sealing with the door side panel 12b.

[0057] In this embodiment, the first edge 151 of the C-pillar outer panel 150 and the second edge 161 of the rear wheel housing outer panel 160 jointly form an outer sealing edge L2 that is sealed with the door side panel 12b. In other words, the first edge 151 of the C-pillar outer panel 150 and the second edge 161 of the rear wheel housing outer panel 160 determine the outer sealing edge L2 that is sealed with the side panel rear section assembly 100 and the door side panel 12b, while the rear end edge of the C-pillar inner panel 110 and the top edge of the side panel inner panel 120 determine the inner sealing edge L1 that is sealed with the side panel rear section assembly 100 and the door side panel 12b, and the inner sealing edge L1 and the outer sealing edge L2 are substantially parallel.

[0058] The first side 151 extends along the third direction N, and the third direction N is set at an angle with the height direction Z of the vehicle, and the second side 161 extends along the first direction X. In this way, the extension direction of the first side 151 can be designed by controlling the angle between the third direction N and the height direction Z of the vehicle, thereby finally determining the outer sealing edge L2 of the side panel rear section assembly 100 and the back door 12 for sealing. Preferably, the angle can be, for example, 45° or 60°, which is conducive to improving the aesthetics of the appearance of the side panel rear section assembly 100 and the back door 12.

[0059] In some embodiments, Figure 4 As shown, the C-pillar outer panel 150 and the rear wheel housing outer panel 160 are an integrated structure. This arrangement is conducive to improving the convenience of manufacturing the C-pillar outer panel 150 and the rear wheel housing outer panel 160 and reducing the manufacturing cost. On the other hand, the two are an integrated structure, which is conducive to improving the strength and impact resistance of the C-pillar outer panel 150 and the rear wheel housing outer panel 160.

[0060] In some embodiments, Figure 6 As shown, the side rear section assembly 100 also includes an inner reinforcement plate 170. The inner reinforcement plate 170 is disposed between the rear wheel housing inner panel 140 and the rear wheel housing outer panel 160. The top of the inner reinforcement plate 170, the top of the rear wheel housing inner panel 140 and the bottom of the side inner panel 120 are all connected, for example, they can be stacked and fixed together by welding. The bottom of the inner reinforcement plate 170 is connected to the bottom of the rear wheel housing outer panel 160, for example, they can be stacked and fixed together by welding.
