The rear side assembly of a car usually includes the CD column frame, inner and outer wheel covers, and side outer panels.

[0003] When assembling the rear side panel assembly on the traditional vehicle body structure, the rear floor frame and the inner wheel cover are usually forcibly attached in the Y direction of the vehicle body to form the rear floor assembly, and then the inner wheel cover and the outer wheel cover are respectively arranged on the inner and outer sides of the CD column frame and forcibly attached in the Y direction of the vehicle body to form a connection, and the outer wheel cover is then forcibly attached to the side panel outer panel in the Y direction of the vehicle body, and finally the rear side panel assembly structure is formed. However, the above-mentioned assembly method will cause the rear side panel assembly to continuously add assembly deviation values ​​in the Y direction of the vehicle body during the assembly process, and accumulate all deviations to the C seam between the side panel outer panel and the rear door, and it is impossible to adjust in the Y direction of the vehicle body to absorb the deviation, which ultimately leads to the phenomenon of excessive surface difference between the rear door outer panel and the side panel outer panel, poor consistency of the C seam gap between the rear door and the rear side panel, and excessive surface difference between the rear door corner window glass and the triangular window. In the prior art, in order to solve the above-mentioned deviations, the stamping molds of the relevant parts are usually optimized so that the deviation values ​​in the Y direction of the vehicle body can be reduced when the relevant parts are assembled, but this will generate additional mold repair costs and time costs.

[0004] Therefore, it is necessary to improve the existing rear side panel assembly structure so that it can effectively reduce the Y-direction deviation value of the vehicle body generated by the rear side panel assembly during assembly, thereby solving the problems of poor consistency of the C-seam gap between the rear door and the rear side panel, and excessive surface difference between the rear door outer panel and the side panel outer panel that affects the aesthetics.

[0008] Furthermore, the outer wheel cover extends vertically downward at one end close to the side outer panel to form a third connection surface for connecting with the side outer panel.

[0009] Furthermore, the outer wheel cover includes a front section, a middle section and a rear section of the outer wheel cover in sequence in the vehicle driving direction, and the front section, the middle section and the rear section of the outer wheel cover are welded to form an integral outer wheel cover.

[0010] Furthermore, the CD column frame is an integrated cast aluminum structure and integrates a C column area, a C column inner and outer panel area, a wheel arch support beam area, a D column area and a top side beam area.

DETAILED DESCRIPTION

[0023] As shown in the figure, the rear side panel assembly provided by the utility model includes a side panel outer panel 1, a CD column frame 2 arranged at the rear end of the vehicle body, and an outer wheel cover 3 arranged between the CD column frame 2 and the side panel outer panel 1, the outer wheel cover 3 is connected to the CD column frame 2 in the vehicle body height direction, and the outer wheel cover 3 is connected to the side panel outer panel 1 in the vehicle body width direction; in this embodiment, the vehicle body height direction mainly refers to the vehicle body Z direction, and the vehicle body width direction refers to the vehicle body Y direction. Since the conventional rear side panel assembly is usually assembled by forcibly sticking the rear floor frame 5 and the inner wheel cover 4 in the vehicle body Y direction and then screwing them, the inner wheel cover 4 and the outer wheel cover 5 are respectively arranged on the inner and outer sides of the CD column frame 2 and are forcibly stuck and screwed in the vehicle body Y direction. At the same time, the outer wheel cover 3 and the side panel outer panel 1 are also screwed in the vehicle body Y direction. After forced pasting and then screwing, the entire rear side panel assembly will eventually generate and superimpose a large number of deviation values ​​in the Y direction of the vehicle body during assembly and cannot be adjusted during the assembly process, resulting in poor consistency in the surface difference between the side panel outer panel 1 and the rear door outer panel and the C-seam gap between the side panel outer panel 1 and the rear door outer panel, thereby affecting the overall appearance assembly accuracy and aesthetics of the body in white; therefore, this embodiment improves the structure of the outer wheel cover 3 and the structure of the CD column skeleton 2, so that the connection relationship between the outer wheel cover 3 structure and the CD column skeleton 2 is changed from forced pasting in the Y direction of the vehicle body to a matching connection in the Z direction of the vehicle body, and then the deviation value in the Y direction of the vehicle body is adjusted and controlled during assembly to ensure that the surface difference between the side panel outer panel 1 and the rear door outer panel is small and the C-seam gap between the side panel outer panel 1 and the rear door outer panel is consistent, thereby improving the overall assembly accuracy of the rear side panel assembly.

[0024] In this embodiment, the bottom of the CD column frame 2 is inclined toward the side outer panel 1 and then extends to form a first connection surface 201, and the outer wheel cover 3 is provided with a second connection surface 301 for matching with the first connection surface 201 at one end close to the CD column frame 2 in the width direction of the vehicle body; Figure 1-Figure 3 As shown, the second connecting surface 202 on the outer wheel cover 3 structure is arranged below the first connecting surface 201 on the CD column frame 2 structure in the Z direction of the vehicle body and has a matching shape, while the second connecting surface 301 can be slidably arranged on the first connecting surface 201 in the Y direction of the vehicle body, thereby adjusting the Y-direction deviation value of the vehicle body generated by the assembly before the outer wheel cover 3 and the CD column frame 2 are connected and fixed.

[0025] In this embodiment, the outer wheel cover 3 extends vertically downward at one end close to the side outer panel 1 to form a third connecting surface 302 for connecting with the side outer panel 1; Figure 1-Figure 3 Since the outer wheel cover 3 is connected to the CD column frame 2 at the connecting end by matching the vehicle body in the Z direction (sliding in the Y direction of the vehicle body), in order to reduce the difficulty of assembly between the side outer panel 1 and the outer wheel cover 3, the third connecting surface 302 is directly adhered to the side outer panel 1 in the Y direction of the vehicle body and then screwed.

[0026] In this embodiment, the outer wheel cover 3 includes an outer wheel cover front section 303, an outer wheel cover middle section 304 and an outer wheel cover rear section 305 in the direction of vehicle travel.

[0027] In this embodiment, the CD column frame 2 is an integrated cast aluminum structure and integrates a C-pillar area, a C-pillar inner and outer panel area, a wheel arch support beam area, a D-pillar area and a top side beam area; the top side beam area, the C-pillar inner and outer panel area and the wheel arch support beam area are all located between the C-pillar area and the D-pillar area, and the C-pillar inner and outer panel area is located between the top side beam area and the wheel arch support beam area; combined with Figure 2 and Figure 5As shown, the CD column frame 2 adopts an integrated die-cast aluminum structure with a high degree of overall structural integration. At the same time, it avoids welding deformation during thermal connection of the aluminum profile structure, improves the dimensional accuracy of the vehicle body, reduces processing time and process tooling development costs, and at the same time, the integrated design effectively improves the overall stiffness of the CD column and significantly improves the bending and torsional stiffness of the vehicle body.

[0028] In this embodiment, it also includes an inner wheel cover 4 and a rear floor frame 5 arranged at the rear floor 6 of the vehicle body close to the rear wheel, the inner wheel cover 4 is arranged between the rear floor frame 5 and the CD column frame 2 and is respectively connected to the rear floor frame 5 and the CD column frame 2 in the width direction of the vehicle body; Figure 1 As shown, due to the adoption of the aforementioned connection structure of the CD column frame 2 and the outer wheel cover 3, the deviation value of the inner wheel cover 4 and the rear floor frame 5 in the Y direction of the vehicle body will not affect the gap and surface difference between the side outer panel 1 and the rear door. At the same time, in order to simplify the difficulty of assembling the inner wheel cover 4 and the rear floor frame 5, the inner wheel cover 4 and the rear floor frame 5 are strongly adhered in the Y direction and then screwed together, and the inner wheel cover 4 and the CD column frame 2 are also strongly adhered in the Y direction and then screwed together.

[0029] In this embodiment, the inner wheel cover 4 includes an inner wheel cover body 401, and the inner wheel cover body 401 is provided with a C-pillar lower reinforcement 402 and a D-pillar lower reinforcement 403 on the side away from the CD column frame 2; Figure 4 As shown, in order to improve the connection strength and torsional rigidity between the entire rear side enclosure assembly, a C-pillar lower reinforcement 402 and a D-pillar lower reinforcement 403 are provided on the side of the inner wheel housing body 401 away from the CD-pillar skeleton 2 .
