[0024] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the invention, and are not intended to limit the scope of the invention.

[0025] In this specification, when describing the structural position of each component, directional expressions such as "upper" and "lower" are not absolute, but relative. When the components are arranged as shown in the figure, these directional expressions are appropriate, but when the position of the components in the figure changes, these directional expressions should also change accordingly. In addition, "inside" and "outside" are defined with reference to the inside-outside direction relative to the vehicle, for example, "outside" refers to the side facing the outside of the vehicle.

[0026] In this specification, "front" and "rear" are defined with reference to the front-rear direction of the vehicle X. In addition, in this specification and the drawings, the X direction represents the longitudinal direction of the vehicle V (i.e., the driving direction of the vehicle), the Y direction represents the lateral direction of the vehicle V (i.e., the direction forming an angle of 90 degrees with respect to the driving direction), and the Z direction represents the vertical direction of the vehicle V (i.e., the direction perpendicular to the ground).

[0027] Below with the help of Figures 1 to 7b A preferred embodiment of the present invention will be described below.

[0028] like Figures 1 to 3 As shown, the side rear body structure 100 of the vehicle V according to the present invention mainly includes a D-pillar inner panel 1, a corner window inner panel 3, a reinforcement panel 4, a side panel outer panel 7, and an insert 5 disposed between the corner window inner panel 3 and the reinforcement panel 4. Figure 4As shown, the side panel outer panel 7 is connected to the corner window inner panel 3 on the outer side of the corner window inner panel 3, that is, the side panel outer panel 7, the reinforcing panel 4 and the corner window inner panel 3 are arranged in sequence from the outside to the inside along the Y direction. A roof side beam 2 extending along the X direction is arranged in front of the D-pillar inner panel 1. The corner window inner panel 3 connects the D-pillar inner panel 1 and the roof side beam 2 on the front side of the D-pillar inner panel relative to the X direction, and has a generally L-shaped shape to form a body corner around the rear quarter window 6 of the vehicle. The shape of the reinforcing panel 4 follows the shape of the corner window inner panel 3, and the reinforcing panel 4 is connected to 2023FAM01358 on the outer side of the corner window inner panel 3.

[0029] The corner window inner panel 3 is connected to the D-pillar inner panel 1 .

[0030] The plug-in 5 includes a shell 51 and an adhesive 52 contained in at least a portion of the shell 51 before expansion, the shell 51 abuts against the corner window inner panel 3, and the adhesive 52 is made of a material with an expansion property so that it can abut against the reinforcing panel 4 after expansion, so that the plug-in 5 fills the Y-direction gap between the corner window inner panel 3 and the reinforcing panel 4.

[0031] like Figure 4 and Figure 5 As shown, the housing 51 of the plug-in 5 includes a base plate 511 and a side wall 512. The base plate 511 is substantially parallel to the corner window inner panel 3, and is surrounded by and connected to the side wall 512. The side wall extends between the corner window inner panel 3 and the reinforcing panel 4 and includes a first end face 5121 and a second end face 5122 opposite to the first end face 5121, wherein the first end face 5121 is oriented toward the reinforcing panel 4 and is separated from the reinforcing panel 4 by a gap L, and the second end face 5122 is oriented toward the corner window inner panel 3 and abuts against the corner window inner panel 3.

[0032] The base plate 511 and the side wall 512 define a first chamber 513 having a first opening 5131 oriented toward the reinforcing plate 4 and a second chamber 514 having a second opening 5141 oriented toward the corner window inner panel 3. Figure 7a and 7b As shown, the adhesive 52 is contained in at least a portion of the first chamber 513 before expansion and abuts against the reinforcing plate 4 via the first opening 5131 after expansion.

[0033] Preferably, the adhesive 52 is a structural adhesive with a Young's modulus greater than 400 MPA. Young's modulus is used to describe the relationship between stress and strain of a material along the loading direction under the action of a force. The size of the Young's modulus indicates the rigidity of the material. The larger the Young's modulus, the less likely it is to deform. For example, when the temperature of the adhesive 52 is equivalent to the temperature of the vehicle paint shop, the adhesive 52 begins to expand, and the expanded surface abuts against the reinforcing plate 4, and the height of the expansion increase is about 3 mm. In some embodiments, the reinforcing plate 4 will also bulge outward as the adhesive 52 expands.

[0034] In the illustrated embodiment, the first end surface 5121 of the side wall 512 has a bent shape adapted to the reinforcing plate 4. More specifically, the first end surface 5121 includes a parallel section 5121a substantially parallel to the corner window inner panel 3 and an inclined section 5121b extending obliquely from the upper end of the parallel section 5121a toward the corner window inner panel 3, so that a gap L is always maintained between the first end surface 5121 and the reinforcing plate 4.

[0035] Preferably, the plug-in 5 further comprises at least one partition 516 separating the first chamber 513. For example, Figure 6 As shown, the plug 5 is provided with an upper partition 5161 and a lower partition 5162, which divide the first chamber 513 into three chambers, upper, middle and lower, and the adhesive 52 is respectively filled in the three chambers. The number and position of the partitions 516 are determined according to actual needs, and the present invention does not limit this.

[0036] like Figure 6 As shown, a support frame 5142 for supporting the substrate 511 is preferably provided in the second chamber 514. According to one embodiment, the support frame is configured as a plurality of staggered reinforcing ribs protruding from the substrate 511 to the corner window inner panel 3 in the second chamber 514 to increase the structural strength of the plug-in 5, and these reinforcing ribs divide the second chamber 514 into a plurality of rectangular chambers.

[0037] The plug-in 5 further includes a buckle 61, which is disposed on the substrate 511 and protrudes from the second chamber 514 via the second opening 5141, and the corner window inner panel 3 is provided with a slot 62 matching the buckle 61, so that the plug-in 5 is buckled and connected to the corner window inner panel 3 and the second end surface 5122 of the side wall 512 abuts against the corner window inner panel 3. Preferably, the upper and lower parts of the substrate 511 are respectively provided with a first buckle 611 and a second buckle 612 protruding toward the corner window inner panel 3, and the first and second slots matching the two buckles are respectively provided on the corner window inner panel 3. The number and position of the buckle 61 and the slot 62 are determined according to actual needs, and the present invention does not limit this. According to other embodiments, the plug-in 5 can also be fixedly connected to the corner window inner panel 3 by other fixing methods and the second end surface 5122 of the side wall 512 abuts against the corner window inner panel 3, and the present invention does not limit this.

[0038] Due to the setting of the plug-in 5, the first-order torsional mode of the body structure 100 at the corner position near the rear quarter window 6 of the vehicle V can reach about 0.2Hz, and the driving noise can be reduced by 1.2dB. In other words, the plug-in 5 not only strengthens the structural strength between the corner window inner panel 3 and the reinforcing panel 4, but also improves the torsional stiffness of the body at the corner position near the rear quarter window 6 of the vehicle, thereby effectively improving the NVH performance of the vehicle, avoiding large vibration and noise during the driving of the vehicle, and ensuring the comfort of the passengers.

[0039] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative ideas of the present invention, technicians in this field can make various changes and improvements to the above-disclosed concepts, but all belong to the protection scope of the present invention.

[0040] The description of the above embodiments is intended to be illustrative rather than restrictive. The protection scope of the present invention is determined by the claims.
