[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are protected by the present utility model.

[0028] Reference Figures 1 to 2 As shown, this embodiment provides a vehicle body side panel reinforcement structure, including a C-pillar reinforcement plate 1, a D-pillar reinforcement plate 2, a side panel inner panel assembly 3, and a side panel outer panel (not shown).

[0029] C-pillar reinforcement plate 1 and D-pillar reinforcement plate 2 are spaced apart along the direction from the front to the rear of the vehicle, and the side panel assembly 3 is connected between C-pillar reinforcement plate 1 and D-pillar reinforcement plate 2.

[0030] Along the width direction of the vehicle, the outer side panel is located on one side of the inner side panel assembly 3, and the outer side panel is connected to the inner side panel assembly 3.

[0031] In practice, the direction from the front to the rear of the vehicle can be referenced. Figure 1 As shown, the C-pillar reinforcement plate 1 and the D-pillar reinforcement plate 2 are spaced apart along the direction from the front to the rear of the vehicle, and a side panel assembly 3 is provided between them. The side panel assembly 3 is connected to the C-pillar reinforcement plate 1 and the D-pillar reinforcement plate 2 respectively.

[0032] For example, the side of the inner panel assembly 3 near the C-pillar reinforcement plate 1 can be welded to the C-pillar reinforcement plate 1, and the side of the inner panel assembly 3 near the D-pillar reinforcement plate 2 can be welded to the D-pillar reinforcement plate 2.

[0033] In this embodiment, the outer side panel is located on one side of the inner side panel assembly 3 along the width direction of the vehicle, specifically the side facing away from the passenger compartment. By connecting the inner side panel assembly 3 with the outer side panel, the structural strength of the entire vehicle side panel reinforcement structure can be increased, that is, the structural strength of the vehicle in the side panel area can be increased to a certain extent. This can improve the body strength of the vehicle with the side panel reinforcement structure, effectively reduce the low-frequency road noise of the vehicle, improve the NVH performance of the whole vehicle, and thus enhance the user's riding experience.

[0034] Furthermore, compared to the traditional method of increasing the thickness of the inner side panel assembly (typically not less than 1.4mm) to enhance the structural strength of the side panel area, this embodiment does not require increasing the material thickness to improve structural strength. Instead, it connects the inner side panel assembly 3 to the outer side panel to increase the structural strength of the side panel area. Therefore, the structural design of the vehicle body side panel reinforcement structure in this embodiment can effectively reduce low-frequency road noise while also facilitating the lightweight design of the entire vehicle.

[0035] Furthermore, tests revealed that vehicles employing the side panel reinforcement structure of this embodiment can reduce road noise by approximately 2.7 dB and reduce overall vehicle weight by about 1.53 kg, thus balancing the design requirements for both passenger comfort and overall vehicle lightweighting.

[0036] The vehicle body side reinforcement structure of this embodiment includes a C-pillar reinforcement plate 1, a D-pillar reinforcement plate 2, an inner side panel assembly 3, and an outer side panel. The C-pillar reinforcement plate 1 and the D-pillar reinforcement plate 2 are spaced apart along the direction from the front to the rear of the vehicle, and the inner side panel assembly 3 is connected between the C-pillar reinforcement plate 1 and the D-pillar reinforcement plate 2. The outer side panel is located on one side of the inner side panel assembly 3 along the width direction of the vehicle, and the inner side panel assembly 3 is connected to the outer side panel. This increases the structural strength of the vehicle in the side area, effectively improving the body strength of the vehicle with this side reinforcement structure, thereby effectively reducing low-frequency road noise and improving the overall NVH performance and user riding experience.

[0037] Reference Figure 1 and Figure 2 As shown, in some embodiments, at least one adhesive structure 4 is provided between the inner side panel assembly 3 and the outer side panel, the adhesive structure 4 being used to connect the inner side panel assembly 3 and the outer side panel.

[0038] In other words, the adhesive connection between the inner side panel assembly 3 and the outer side panel is achieved through the adhesive structure 4. This connection method is not only quick but also has good reliability.

[0039] When performing the adhesive connection, the adhesive structure 4 can be first bonded to the side of the inner side panel assembly 3 near the outer side panel, and then the side of the outer side panel facing the inner side panel assembly 3 can be bonded to the adhesive structure 4. Alternatively, the adhesive structure 4 can be first bonded to the side of the outer side panel near the inner side panel assembly 3, and then the side of the inner side panel assembly 3 near the outer side panel can be bonded to the adhesive structure 4.

[0040] The inner side panel assembly 3 and the outer side panel are connected by adhesive structure 4. The whole operation is not only convenient, but also does not affect the appearance of the outer side panel.

[0041] Alternatively, in other implementations, the inner side panel assembly 3 and the outer side panel can also be welded together.

[0042] Reference Figure 1 and Figure 2 As shown, in some embodiments, the adhesive structure 4 is an annular structure extending circumferentially along the inner side panel assembly 3.

[0043] By setting the adhesive structure 4 as a ring structure extending circumferentially, the adhesive structure 4 can form a larger adhesive area between the inner side panel assembly 3 and the outer side panel, thereby further improving the bonding strength between the inner side panel assembly 3 and the outer side panel. At the same time, the adhesive structure 4 uses less material to save costs and can reduce weight to a certain extent.

[0044] For example, the adhesive structure 4 can be shaped as follows: Figure 2 The trapezoidal shape shown can also be a circular shape or a triangular shape, etc., and this embodiment is not limited to these.

[0045] For example, the adhesive structure 4 can be an expanding adhesive, which can ensure a solid bond while allowing the expanding adhesive to fully fill the space between the inner side panel assembly 3 and the outer side panel after expansion, so as to facilitate the bonding operation between the two.

[0046] Alternatively, in other implementations, the adhesive structure 4 can be made of epoxy adhesive or polyurethane adhesive, etc.

[0047] Reference Figure 1 As shown, in some embodiments, the side panel assembly 3 includes a side panel 31 and a reinforcement 32.

[0048] The inner side panel 31 is connected between the C-pillar reinforcing plate 1 and the D-pillar reinforcing plate. The reinforcing member 32 is located on the side of the inner side panel 31 near the outer side panel, and the reinforcing member 32 is connected to the outer side panel.

[0049] Specifically, the side panel assembly 3 can be configured to include two parts, namely the side panel 31 and the reinforcing member 32. The setting of the reinforcing member 32 can effectively improve the structural strength of the side panel 31, which in turn helps to improve the structural strength of the entire vehicle side panel reinforcement structure, thereby improving the vehicle's NVH performance.

[0050] In some embodiments, the inner side panel 31 and the reinforcing member 32 can be bonded together using an adhesive structure 4. One side of the adhesive structure 4 is connected to the side of the inner side panel 31 facing away from the passenger compartment, and the other side is connected to the side of the reinforcing member 32 facing away from the outer side panel. For example, the adhesive structure 4 can be an expanding adhesive. By using expanding adhesive, noise generated by vibration between the inner side panel 31 and the reinforcing member 32 can be reduced, effectively improving the overall NVH performance of the vehicle and enhancing the user's riding experience.

[0051] Furthermore, by connecting the reinforcing member 32 to the side panel, the overall structural strength of the entire vehicle side reinforcement structure can be increased, thereby effectively improving the vehicle's body strength in the side area, thus effectively improving the vehicle's NVH performance and enhancing the user's riding experience.

[0052] In some embodiments, the outer side panel and the reinforcing member 32 can be bonded together using an adhesive structure 4. One side of the adhesive structure 4 is connected to the side of the reinforcing member 32 near the outer side panel, and the other side is connected to the side of the outer side panel near the inner side panel 31. For example, the adhesive structure 4 can be an expanding adhesive. By using expanding adhesive, noise generated by vibration between the outer side panel and the reinforcing member 32 can be reduced, effectively improving the NVH performance of the entire vehicle and enhancing the user's riding experience.

[0053] Reference Figure 1 As shown, in some embodiments, the reinforcement 32 extends along the direction from the C-pillar reinforcement plate 1 to the D-pillar reinforcement plate 2.

[0054] The end of the reinforcing member 32 near the C-pillar reinforcing plate 1 is connected to the C-pillar reinforcing plate 1. The end of the reinforcing member 32 near the D-pillar reinforcing plate 2 is connected to the D-pillar reinforcing plate 2.

[0055] In this embodiment, only one end of the reinforcing member 32 near the C-pillar reinforcing plate 1 can be connected to the C-pillar reinforcing plate 1; or only one end of the reinforcing member 32 near the D-pillar reinforcing plate 2 can be connected to the D-pillar reinforcing plate 2; or both the end of the reinforcing member 32 near the C-pillar reinforcing plate 1 and the end of the reinforcing member 32 near the D-pillar reinforcing plate 2 can be connected to the D-pillar reinforcing plate 2.

[0056] When the end of the reinforcing member 32 near the C-pillar reinforcing plate 1 is connected to the C-pillar reinforcing plate 1, the structural strength of the entire vehicle side reinforcement structure can be further improved, thereby further enhancing the structural strength of the vehicle body in the side area and improving the NVH performance of the whole vehicle.

[0057] Similarly, when the end of the reinforcing member 32 near the D-pillar reinforcing plate 2 is connected to the D-pillar reinforcing plate 2, the structural strength of the entire vehicle side reinforcement structure can be further improved, thereby further improving the structural strength of the vehicle body in the side area and improving the NVH performance of the whole vehicle.

[0058] When the end of the reinforcing member 32 near the C-pillar reinforcing plate 1 is connected to the C-pillar reinforcing plate 1 and the end of the reinforcing member 32 near the D-pillar reinforcing plate 2 is connected to the D-pillar reinforcing plate 2, the structural strength of the entire vehicle side reinforcement structure can be significantly improved, thereby effectively improving the vehicle's NVH performance.

[0059] For example, the reinforcing member 32 includes a reinforcing beam plate, that is, the reinforcing member 32 can be a plate-shaped structure, so as to make reliable contact with the inner side panel 31 and then weld it together.

[0060] For example, the material of the reinforcing beam can be an alloy or a metal to ensure that the reinforcing member 32 itself has sufficient structural strength.

[0061] For example, the reinforcing member 32 and the inner side panel 31 can be welded together to achieve a quick and reliable connection between the reinforcing member 32 and the inner side panel 31. Alternatively, in other implementations, the reinforcing member 32 can also be connected to the inner side panel 31 by means of screws or other methods.

[0062] Reference Figure 1 As shown, in some embodiments, the inner side panel 31 includes a frame 312 with a corner window 311, the frame 312 including a top frame 313, a bottom frame 315 and a longitudinal frame 314 connecting the top frame 313 and the bottom frame 315.

[0063] The reinforcing member 32 is connected to the side of the bottom frame 315 facing the outer side panel.

[0064] Specifically, the vehicle's height can be referenced. Figure 1 As shown in the vertical direction, the frame 312 of the inner side panel 31 includes a top frame 313, a bottom frame 315 located below the top frame 313, and two vertical frames 314 connecting the top frame 313 and the bottom frame 315. The top frame 313, the bottom frame 315, and the two vertical frames 314 enclose a closed corner window 311 for installing or accommodating corner window glass.

[0065] In this embodiment, the reinforcing member 32 can be specifically connected to the bottom frame 315 so as to make full use of the position space on the bottom frame 315 to arrange the reinforcing member 32.

[0066] Reference Figure 1As shown, the thickness of the reinforcing member 32 is not less than 0.8 mm along the width direction of the vehicle.

[0067] By reasonably setting the thickness of the reinforcing component 32, it is possible to effectively ensure that the structural strength of the side reinforcement structure of the vehicle body is sufficient to improve NVH performance, while the thickness of the reinforcing component 32 can be reduced. This not only saves costs but also helps to achieve the lightweight design of the whole vehicle.

[0068] For example, the thickness of the reinforcing member 32 can be set to 0.8 mm, or it can be set to 0.9 mm or 1 mm.

[0069] Optionally, the thickness of the inner side panel 31 along the width direction of the vehicle is not less than 0.8 mm.

[0070] By reasonably setting the thickness of the inner side panel 31, it is possible to effectively ensure that the structural strength of the side panel reinforcement structure itself is sufficient to improve NVH performance, while the thickness of the inner side panel 31 can be reduced. This not only saves costs but also helps to achieve the lightweight design of the whole vehicle.

[0071] For example, the thickness of the inner side panel 31 can be set to 0.8 mm, or it can be set to 0.9 mm or 1 mm.

[0072] Reference Figure 1 and Figure 2 As shown, this embodiment provides a vehicle that includes a side panel reinforcement structure.
