Description

Technical Field

[0001] This invention relates to a vehicle connection structure, and more particularly to a vehicle side rear connection structure and a vehicle. Background Technology

[0002] As people's living standards improve, they have higher requirements for the comfort of cars, so the performance of the car body directly affects the comfort of passengers.

[0003] During operation, automobiles experience torsional deformation, road noise, and wind noise. Low torsional stiffness exacerbates this deformation, leading to issues with abnormal noises, durability, and handling. More importantly, these noises directly impact passenger comfort. Torsional stiffness directly affects the vehicle's torsional modes; higher stiffness results in higher torsional mode frequencies and better resistance to low-frequency excitations. Torsional stiffness, torsional modes, and NTF (noise, vibration, and harshness) are crucial NVH performance indicators in automotive development, determining the overall vehicle performance.

[0004] Currently, the rear side structure of hatchback models has significant limitations, with small cavities and low interconnectivity, making it difficult to improve torsional stiffness and modal characteristics. This necessitates the use of numerous reinforcing parts, resulting in high costs. Summary of the Invention

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] Please see Figure 1 The present invention discloses a rear side panel connection structure for a vehicle, including a C-pillar inner panel 1, a wheel arch inner panel 2, an upper side beam inner panel 3, an upper side beam reinforcing plate 4, a rear reinforcing plate 5, a C-ring connector 6, and a D-pillar 7.

[0034] The C-pillar inner panel 1 is welded and fixedly connected to the upper side beam inner panel 3, the rear reinforcing plate 5, and the wheel arch inner panel 2 along the vehicle height direction. The C-ring connector 6 is fixedly connected to the upper side beam inner panel 3, the C-pillar inner panel 1, and the wheel arch inner panel 2. The upper side beam reinforcing plate 4 is fixedly connected to the upper side beam inner panel 3.

[0035] More specifically, in this embodiment, the rear reinforcing plate 5, the upper beam inner plate 3, and the upper beam reinforcing plate 4 are arranged along the length of the vehicle, and the rear reinforcing plate 5 is fixedly connected to the upper beam inner plate 3 and the upper beam reinforcing plate 4 by welding.

[0036] Please see Figure 1 and Figure 5 The C-ring connector 6 extends along the vehicle height direction in a U-shaped groove. The C-ring connector 6 and the C-pillar inner panel 1 are arranged side-by-side along the vehicle width direction. The groove of the C-ring connector 6 faces the C-pillar inner panel 1 and is fixed to it by welding. The upper end of the C-ring connector 6 is welded to the upper side beam inner panel 3 and the rear reinforcing plate 5, and the lower end of the C-ring connector 6 is welded to the wheel arch inner panel 2.

[0037] More specifically, the C-ring connector 6, together with the C-pillar inner plate 1 and the wheel arch inner plate 2, forms a C-ring cavity 110. The C-ring cavity 110 has a square cavity structure along the vehicle height direction. Furthermore, the upper beam inner plate 3, the C-ring connector 6, and the wheel arch inner plate 2 together form a C-ring enclosing cavity 130, which increases the rigid support structure of the C-ring connector 6 for the wheel arch inner plate 2. Therefore, the C-ring cavity 110 and the C-ring enclosing cavity 130 are not only structurally stable, but also allow for the installation of a seatbelt retractor within the C-ring cavity 110, effectively utilizing the cavity space. The C-ring connector 6 has a square opening facing the vehicle's interior space, through which the seatbelt retractor is installed within the C-ring cavity, facilitating subsequent maintenance and replacement of the seatbelt retractor.

[0038] Please see Figure 3 The upper side beam reinforcing plate 4 and the upper side beam inner plate 3 enclose each other to form an upper side beam cavity 150. The enclosing structure of the upper side beam cavity 150 greatly enhances the strength of the vehicle's upper side beam, thereby improving the vehicle body's torsional stiffness.

[0039] Please see Figure 1 and Figure 4 The D-pillar 7 is fixedly connected to the rear reinforcing plate 5, the inner C-pillar plate 1, and the inner wheel arch plate 2. The D-pillar 7 is inclined along the vehicle height direction and is in the shape of a U-shaped groove. The D-pillar 7 and the inner C-pillar plate 1 are arranged side by side along the vehicle width direction. The groove of the D-pillar 7 faces the inner C-pillar plate 1 and is fixed to the inner C-pillar plate 1 by welding.

[0040] More specifically, the D-pillar 7 and the inner panel 1 of the C-pillar together form a D-ring cavity 120. The D-cavity 120 has a square cavity structure along the vehicle height direction, which effectively increases the structural strength of the vehicle's D-pillar.

[0041] Please see Figure 1 and Figure 2 The upper side beam inner plate 3 and the rear reinforcing plate 5 are fixedly connected by welding. The wheel arch inner plate 2, the upper side beam inner plate 3, and the rear reinforcing plate 5 are fixedly connected to the C-pillar inner plate 1 by welding. The outer walls of the C-ring cavity 110 and the D-ring cavity 120, together with the upper side beam inner plate 3, the rear reinforcing plate 5, and the wheel arch inner plate 2, form an annular reinforcing part. In this embodiment, the upper side beam inner plate 3, the upper side beam reinforcing plate 4, the rear reinforcing plate 5, the C-ring cavity 110, and the D-ring cavity 120 are fixedly connected to form a "Π"-shaped structure, and together with the C-pillar inner plate 1 and the wheel arch inner plate 2, they form the annular reinforcing part, making the entire rear side structure present an integral and coherent structure, thereby improving the torsional stiffness, torsional mode, and NTF performance of the vehicle body.

[0042] Please continue reading. Figure 1 and Figure 2 The rear side panel connection structure of the vehicle of the present invention also includes a wheel arch reinforcement beam 9. The wheel arch reinforcement beam 9 is fixedly connected to the inner wheel arch plate 2 and the C-ring connector 6. More specifically, the wheel arch reinforcement beam 9 includes a first reinforcement beam 91 and a second reinforcement beam 92. The first reinforcement beam 91 extends along the vehicle height direction and is fixedly connected to the inner wheel arch plate 2 and the C-ring connector 6. More specifically, the first reinforcement beam 91 is welded to the inner wheel arch plate 2, and the lower end of the C-ring connector 6 is welded to the inner wheel arch plate 2, while the other end is fixedly welded to the first reinforcement beam 91. The second reinforcement beam 92 is fixedly connected to the D-pillar 7, the inner wheel arch plate 2, and the C-ring connector 6. More specifically, the second reinforcement beam 92 extends along the vehicle width direction. The second reinforcement beam 92 is welded to the inner wheel arch plate 2, and one end of it is welded to the lower end of the D-pillar.

[0043] A wheel arch reinforcement plate 8 is also included between the first reinforcing beam 91 and the second reinforcing beam 92. The wheel arch reinforcement plate 8 is fixedly connected to the inner wheel arch plate 2, the C-ring connector 6, the first reinforcing beam 91, and the second reinforcing beam 92. More specifically, the wheel arch reinforcement plate 8 extends along the length direction of the vehicle. The wheel arch reinforcement plate 8 is welded and fixed to the inner wheel arch plate 2, and both ends of the wheel arch reinforcement plate 8 along the length direction of the vehicle are welded and fixed to the second reinforcing beam 92 and the first reinforcing beam 91, respectively. Furthermore, the upper end of the wheel arch reinforcement plate 8 along the height direction of the vehicle is welded and fixed to the lower end of the C-ring connector 6.

[0044] Thus, the upper beam inner plate 3, the upper beam reinforcing plate 4, the rear reinforcing plate 5, the C-ring connector 6, the D-pillar 7, the C-pillar inner plate 1, the wheel arch inner plate 2, the second reinforcing beam 92, the wheel arch reinforcing plate 8, and the first reinforcing beam 91 together form a "Ⅱ" shape. The aforementioned annular structure of this invention ensures sufficient structural support and forms a continuous cavity with the lower vehicle body, exhibiting integrity and continuity. It can effectively resist deformation, decompose forces, and ensure the integrity of the overall force distribution and transmission path, thereby improving the vehicle's torsional, modal, and NTF performance.

[0045] Please see Figure 2 and Figure 3 The rear side panel connection structure of the vehicle of the present invention also includes a floor crossbeam assembly 10. The floor crossbeam assembly 10 is fixedly connected to the inner wheel arch panel 2 and the first reinforcing beam 91 of the wheel arch reinforcing beam 9. More specifically, the floor crossbeam assembly 10 extends along the width direction of the vehicle, one end of which is fixedly connected to the first reinforcing beam 91 and fixed to the first reinforcing beam 91 by welding, and the other end of which extends into the vehicle space and is fixedly connected to the floor crossbeam assembly 10 on the other side of the vehicle.

[0046] The inner wheel arch panel 2, together with the C-ring connector 6, the first reinforcing beam 91 of the wheel arch reinforcing beam 9, and the floor crossbeam assembly 10, forms a wheel arch reinforcing cavity 140. The structure of the wheel arch reinforcing cavity 140 satisfies the rigid support provided by the C-ring connector 6, the first reinforcing beam 91, and the floor crossbeam assembly 10 to the inner wheel arch panel 2. Furthermore, the floor crossbeam assemblies 10 on both sides of the vehicle are connected to form a ring, enhancing the rigid connection characteristics of the rear of the vehicle body.

[0047] The rear side panel connection structure of the vehicle of the present invention also includes a floor crossbeam reinforcing plate 16, which is fixedly connected to the inner wheel arch panel 2 and the floor crossbeam assembly 10. More specifically, the floor crossbeam reinforcing plate 16 extends along the length of the vehicle, is welded and fixed to the inner wheel arch panel 2, and one end of it is welded and fixed to the floor crossbeam assembly 10. The floor crossbeam reinforcing plate 16 further enhances the rigidity of the floor crossbeam assembly 10.

[0048] The rear side panel connection structure of the vehicle of the present invention also includes a rear panel assembly 11. The rear panel assembly 11 is fixedly connected to the rear reinforcing plate 5, and one end is welded to the rear reinforcing plate 5, and the other end is welded to the inner wheel arch plate 2.

[0049] The rear side panel connection structure of the vehicle of the present invention also includes a wheel arch outer plate 12. The wheel arch outer plate 12 is welded and fixedly connected to the C-pillar inner plate 1 and the wheel arch inner plate 2. The wheel arch outer plate 12 and the wheel arch inner plate 2 are arranged opposite to each other to form a wheel arch cavity. The wheel arch cavity is suitable for the vehicle tire to rotate within it to protect the vehicle tire and effectively reduce vehicle noise, etc.

[0050] The present invention also discloses an automobile, including the vehicle side rear connection structure as described above.

[0051] Please see Figure 9 The vehicle includes a seatbelt retractor 15. The seatbelt retractor 15 is disposed within the C-ring cavity 110 and mounted on the C-ring connector 6, and the seatbelt extends out of the C-ring cavity 110 via the C-ring connector 6.

[0052] Please see Figure 7 and Figure 8 The vehicle also includes a seatbelt guide ring 13. The seatbelt guide ring 13 is disposed on the C-ring connector 6, and the seatbelt passes through the seatbelt guide ring 13 and extends out of the C-ring cavity 110.

[0053] More specifically, the seat belt guide ring 13 has a seat belt outlet 132, and a guide ring fixing member 131 is provided around the seat belt outlet 132. The seat belt guide ring 13 is fixed to the C-ring connector 6 by the seat belt fixing member 131. In this embodiment, the seat belt fixing member 131 is a rivet. In other embodiments, the seat belt fixing member 131 may also be a screw, which is not particularly limited here. The seat belt extends out of the C-ring connector 6 through the seat belt outlet 132.

[0054] Please see Figure 7 The C-ring connector 6 has seat belt mounting points 14 around the seat belt outlet 132. One end of the seat belt is fixed to the seat belt retractor 15, and the other end is fixed to the seat belt mounting point 14. The passenger pulls the seat belt wound on the seat belt retractor 15 outward through the seat belt outlet 132, and the seat belt is wrapped around the passenger's body to ensure passenger safety in case of emergencies during vehicle operation.

[0055] In this embodiment, the seat belt retractor 15 is disposed within the C-ring cavity 110, which can effectively utilize the cavity space and reduce the increase in cost and weight caused by the reinforcement plates installed on other structures for the seat belt.

[0056] The present invention provides a vehicle side rear connection structure that presents an integral and coherent appearance to the vehicle, thereby improving the vehicle body's torsional stiffness, torsional mode, and NTF performance.
