Description

Technical Field

[0001] This article relates to vehicle body structure technology, particularly a type of vehicle body and vehicle. Background Technology

[0002] With changing needs for car use, MPVs (Multi-Purpose Vehicles) are becoming increasingly common. MPVs typically have 6-7 seats, and the rear doors are large enough to accommodate passengers in the second and third rows. Therefore, the rear doors are often sliding doors. Sliding doors utilize upper, middle, and lower guide rails on the upper, middle, and lower sections of the vehicle body to facilitate sliding.

[0003] The central guide rail groove assembly of the sliding door causes discontinuity in the C-pillar structure, resulting in low body modal stiffness and consequently low crash test scores and high vibration and noise. Traditional C-pillar reinforcement structures use reinforcing plates, which have poor reinforcement effects; moreover, the reinforcement effect of reinforcing plates on the central guide rail groove assembly of the sliding door is particularly weak. Summary of the Invention

[0004] This application provides a vehicle body and a vehicle, the vehicle body including a C-pillar reinforcement member, which can effectively strengthen the guide rail groove assembly in the middle of the sliding door and uses less material. At the same time, the C-pillar reinforcement member helps to form a continuous C-pillar structure, thereby helping to improve the vehicle body modalities and stiffness, and thus helping to improve the crash score and reduce vibration noise.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0031] like Figure 1 As shown in the figure, this application embodiment provides a vehicle body, which includes an upper C-pillar, a lower C-pillar, a sliding door center guide rail groove assembly, and a C-pillar reinforcement 100. The C-pillar reinforcement 100 includes a first connecting portion 110, a second connecting portion 120, and a third connecting portion 130, both of which are connected to the first connecting portion 110; the first connecting portion 110 is connected to the sliding door center guide rail groove assembly, the second connecting portion 120 is connected to the upper C-pillar, and the third connecting portion 130 is connected to the lower C-pillar.

[0032] The central guide rail groove assembly of the sliding door causes discontinuity in the C-pillar structure, resulting in low body modal stiffness and consequently low crash test scores and high vibration and noise. Existing C-pillar reinforcement structures use reinforcing plates, but due to the groove structure in the central guide rail groove assembly, the Z-axis (body height direction) cross-sectional dimensions of the reinforcing plate are limited, leading to poor reinforcement. Furthermore, the reinforcement effect of the plate on the central guide rail groove assembly is particularly weak.

[0033] In order to form a continuous C-pillar structure, improve the modal characteristics and stiffness of the vehicle body, improve the crash score, and reduce vibration noise, this application provides a vehicle body in which the C-pillar reinforcement 100 connects the upper part and the lower part of the C-pillar, thus forming a continuous C-pillar structure, improving the modal characteristics and stiffness of the vehicle body, thereby improving the crash score. In use, the continuous C-pillar structure can reduce the amplitude of the C-pillar and the vehicle body, thereby reducing vibration noise.

[0034] The first connecting portion 110 is located in the middle of the C-pillar reinforcement 100. The C-pillar reinforcement 100 is connected to the central guide rail groove assembly of the sliding door through its first connecting portion 110, so that the C-pillar reinforcement 100 has a good reinforcing effect on the central guide rail groove assembly of the sliding door. The C-pillar reinforcement 100 is connected to the upper part of the C-pillar through the second connecting portion 120, which is located at the upper part of the C-pillar reinforcement 100. The C-pillar reinforcement 100 is connected to the lower part of the C-pillar through the third connecting portion 130, which is located at the lower part of the C-pillar reinforcement 100.

[0035] The C-pillar reinforcement 100 connects the upper and lower parts of the C-pillar, thus forming a continuous C-pillar structure. This improves the modal rigidity and stiffness of the vehicle body, thereby increasing the crash score. In use, the continuous C-pillar structure reduces the amplitude of the C-pillar and the vehicle body, thereby reducing vibration noise.

[0036] In one exemplary implementation, such as Figure 1 As shown, the first connecting part 110 includes a connecting plate 111 and a side panel. The side panel is connected to the circumferential edge of the connecting plate 111 and together with the connecting plate 111, forms a cavity. The sliding door center guide rail groove assembly includes a connecting recess 411, the shape of which is adapted to the shape of the cavity so that the connecting recess 411 is fitted into the cavity. The side panel is provided with a fixing part for connecting to the sliding door center guide rail groove assembly, and the connecting plate 111 may also be provided with a fixing part for connecting to the sliding door center guide rail groove assembly.

[0037] The fixing part may include a connecting hole 150 and fasteners, including but not limited to rivets, screws, pins and weld studs.

[0038] The cavity is recessed towards the inside of the vehicle body to accommodate the connecting recess 411 on the outer plate 410 of the middle guide rail groove assembly of the sliding door, which helps to improve the structural strength of the middle guide rail groove assembly of the sliding door.

[0039] The side panel surrounds the connecting plate 111 and has a fixing part for connecting with the central guide rail groove assembly of the sliding door. The connecting plate 111 may also have a fixing part for connecting with the central guide rail groove assembly of the sliding door. The fixing part may include a connecting hole 150 and a rivet, thereby providing a basis for the quick connection between the C-pillar reinforcement 100 and the central guide rail groove assembly of the sliding door. The C-pillar reinforcement 100 and the central guide rail groove assembly of the sliding door can then be quickly connected and fixed by the rivet, which also facilitates disassembly and maintenance during subsequent use.

[0040] In one example, the cavity is shaped to fit the connection recess 411 of the central guide rail groove assembly of the sliding door.

[0041] In one example, the connecting recess 411 on the outer plate 410 of the middle guide rail groove assembly of the sliding door is embedded in the cavity of the first connecting portion 110 of the C-pillar reinforcement 100 and is fixedly connected to the first connecting portion 110, thereby connecting the C-pillar reinforcement 100 to the middle guide rail groove assembly of the sliding door.

[0042] The connecting recess 411 on the outer plate 410 of the central guide rail groove can be embedded in the cavity of the first connecting portion 110 of the C-pillar reinforcement 100, so the thickness of the reinforcement is not excessively restricted. Since the shape of the C-pillar reinforcement 100 and the connecting recess 411 on the outer plate 410 of the central guide rail groove are compatible, the C-pillar reinforcement 100 has a good reinforcement effect on the central guide rail groove assembly of the sliding door, thereby further improving the modal and rigidity of the vehicle body, thereby improving the collision score and reducing vibration noise.

[0043] In one example, the longitudinal sections of both the cavity and the connecting recess 411 are right-angled trapezoidal shapes. The connecting recess 411 can be embedded in the cavity and the outer wall of the connecting recess 411 can fit against the inner wall of the cavity, effectively avoiding collision noise caused by shaking.

[0044] In this embodiment, the connecting recess 411 on the outer plate 410 of the central guide rail groove can be embedded in the cavity of the first connecting portion 110 of the C-pillar reinforcement 100, so the thickness of the reinforcement is not excessively restricted. Since the shape of the C-pillar reinforcement 100 and the connecting recess 411 on the outer plate 410 of the central guide rail groove are compatible, the C-pillar reinforcement 100 has a good reinforcement effect on the central guide rail groove assembly of the sliding door, thereby further improving the modal and rigidity of the vehicle body, thereby improving the collision score and reducing vibration noise.

[0045] In one exemplary implementation, such as Figure 1As shown, the side panel includes a first side panel 112, a second side panel 113, a third side panel 114, and a fourth side panel 115 connected end to end; the first side panel 112 is located in front of the third side panel 114, and the second side panel 113 is located below the fourth side panel 115; the first side panel 112, the second side panel 113, the third side panel 114, and the fourth side panel 115 are all provided with fixing parts.

[0046] In one example, such as Figure 1 As shown, the first side plate 112 corresponds to the lower base of the right trapezoid in the longitudinal section, the second side plate 113 corresponds to the inclined leg of the right trapezoid in the longitudinal section, the third side plate 114 corresponds to the upper base of the right trapezoid in the longitudinal section, and the fourth side plate 115 corresponds to the right leg of the right trapezoid in the longitudinal section.

[0047] In one example, two connecting holes 150 can be provided on the first side plate 112, two connecting holes 150 on the second side plate 113, two connecting holes 150 on the third side plate 114, and two connecting holes 150 on the fourth side plate 115. The two connecting holes 150 on the first side plate 112 can be distributed along the Z-direction of the vehicle body, and the two connecting holes 150 on the third side plate 114 can be distributed along the Y-direction of the vehicle body. This is because the Z-direction length of the third side plate 114 is shorter, and the third side plate 114 needs to be firmly fixed to the connecting recess 411; therefore, the two connecting holes 150 on the third side plate 114 can be distributed along the Y-direction of the vehicle body. The connecting plate 111 can have four connecting holes 150. The connecting holes 150 on the first side plate 112, the second side plate 113, the third side plate 114, the fourth side plate 115, and the connecting plate 111 are all used to fix the connecting recess 411 on the outer plate 410 of the middle guide rail groove, thereby forming a firm fix between the C-pillar reinforcement 100 of the C-pillar and the outer plate 410 of the middle guide rail groove assembly of the sliding door.

[0048] In one exemplary embodiment, the connecting plate 111 has a receiving hole 116 for a pull cable of the central guide rail of the sliding door to pass through. The pull cable is used to pull the central guide rail of the sliding door along the central guide rail groove assembly.

[0049] In one example, such as Figure 1 As shown, the receiving hole 116 is rectangular, with its long side parallel to the length direction (X-direction) of the vehicle body and its wide side parallel to the height direction (Z-direction) of the vehicle body. The extension direction of the sliding door's central guide rail groove assembly is parallel to the length direction of the vehicle body. The longer length of the receiving hole 116 in the length direction parallel to the vehicle body facilitates the smooth pulling of the cable along the central guide rail of the sliding door and its movement along the length direction of the vehicle body during this process.

[0050] With this implementation, the receiving hole 116 facilitates the smooth pulling of the cable along the central guide rail of the sliding door and its movement along the length of the vehicle body during the process.

[0051] In one exemplary implementation, such as Figure 1 As shown, the second connecting portion 120 includes: an upper extension plate 121, located above the first connecting portion 110 and connected to the first connecting portion 110, the upper extension plate 121 and the first connecting portion 110 enclosing each other to form an upper cavity; the upper extension plate 121 is provided with a fixing part for connecting to the upper part of the C-pillar. The upper cavity is mainly used for the connection between the C-pillar reinforcement 100 and the upper part of the C-pillar, and the upper cavity can protect the connection point between the C-pillar reinforcement 100 and the upper part of the C-pillar, preventing bending and breakage at the connection point.

[0052] In one example, such as Figure 1 As shown, the upper extension plate 121 and the fourth side plate 115 enclose an upper cavity, and the upper extension plate 121 is curled. The upper extension plate 121 is provided with a fixing part, which may include a connecting hole 150, and further, the fixing part may include a riveting hole 500. Compared with the welding connection commonly used in this field, riveting connection is beneficial for quick disassembly. At the same time, riveting connection has less deformation, lower environmental requirements, good impact resistance, good vibration resistance, good fatigue resistance, and simple process equipment. The curled shape of the upper extension plate 121 helps to avoid generating too many sharp edges, which is beneficial for the integral forming of the C-pillar reinforcement 100, and also helps to avoid sharp edges from damaging other parts of the vehicle body.

[0053] In one exemplary implementation, such as Figure 1 As shown, the third connecting portion 130 includes: a lower extension plate 131, located below the first connecting portion 110 and connected to the first connecting portion 110, the lower extension plate 131 and the first connecting portion 110 enclosing to form a lower cavity; the lower extension plate 131 is provided with a fixing part for connecting to the lower part of the C-pillar. The lower cavity is mainly used for connecting the C-pillar reinforcement 100 to the lower part of the C-pillar, and the lower cavity can protect the connection point between the C-pillar reinforcement 100 and the lower part of the C-pillar, preventing bending and breakage at the connection point.

[0054] In one example, such as Figure 1 As shown, the lower extension plate 131 and the second side plate 113 enclose a lower cavity, and the lower extension plate 131 is curled. The lower cavity can be crescent-shaped. The lower extension plate 131 is provided with a fixing part, which may include a connecting hole 150, and further, the fixing part may include a riveting hole 500. Compared with the welding connection commonly used in this field, riveting connection is beneficial for quick disassembly. At the same time, riveting connection has less deformation, lower environmental requirements, good impact resistance, good vibration resistance, good fatigue resistance, and simple process equipment. The curled shape of the lower extension plate 131 helps to avoid generating too many sharp edges, which is beneficial for the integral forming of the C-pillar reinforcement 100, and also helps to avoid sharp edges from damaging other parts of the vehicle body.

[0055] In one exemplary implementation, such as Figure 1 and Figure 2 As shown, the upper part of the C-pillar includes a C-pillar upper tube beam 210, and the upper extension plate 121 is provided with an installation notch 140 for inserting the C-pillar upper tube beam 210. The fixing part on the upper extension plate 121 is fixedly connected to the C-pillar upper tube beam 210.

[0056] The mounting notch 140 on the upper extension plate 121 is located at the top of the upper extension plate 121. The C-column upper tube beam 210 extends upward along the Z direction through the mounting notch 140 of the upper extension plate 121.

[0057] With this implementation method, the installation notch 140 allows the pipe beam 210 on the C-column to extend upwards without obstruction.

[0058] In one exemplary implementation, such as Figure 1 and Figure 2 As shown, the lower part of the C-pillar includes a lower C-pillar tube beam 310, and the lower extension plate 131 is provided with an installation notch 140 for inserting the lower C-pillar tube beam 310. The fixing part on the lower extension plate 131 is fixedly connected to the lower C-pillar tube beam 310.

[0059] The mounting notch 140 on the lower extension plate 131 is located at the bottom of the lower extension plate 131. The C-column lower tube beam 310 extends downward along the Z direction through the mounting notch 140 of the lower extension plate 131.

[0060] With this implementation method, the installation notch 140 allows the C-column lower tube beam 310 to extend downwards without obstruction.

[0061] In one exemplary implementation, such as Figure 1 As shown, a reinforcing structure is provided inside the lower cavity, and the reinforcing structure is connected to the cavity wall of the lower cavity. The cavity wall of the lower cavity includes the inner side plate of the lower extension plate 131 and the second side plate 113.

[0062] Through this implementation method, without excessively increasing the weight of the C-pillar reinforcement 100, the reinforcing structure in the lower cavity helps to improve the mechanical strength of the C-pillar reinforcement 100 and prevent the C-pillar reinforcement 100 from deforming under external force.

[0063] In one exemplary implementation, such as Figure 1 As shown, the reinforcing structure includes multiple spaced reinforcing ribs 132, which extend from the first connecting portion 110 to the lower extension plate 131.

[0064] The thickness of the reinforcing rib 132 ranges from 10mm to 50mm, such as 10mm, 20mm, 30mm, 40mm, and 50mm. This ensures that the reinforcing rib 132 provides good reinforcement while also considering the weight and processing cost of the C-pillar reinforcement 100. Of course, the thickness range of the reinforcing rib 132 is not limited to the above ranges.

[0065] In one exemplary implementation, such as Figure 1 As shown, at least one fixing part is provided on at least one reinforcing rib 132.

[0066] In one example, such as Figure 1 As shown, there are two reinforcing ribs 132. The top of the reinforcing rib 132 near the first side plate 112 is flush with the bottom of the mounting notch 140. A connecting hole 150 is provided on this reinforcing rib, which can be a riveting hole 500 for riveting the C-pillar lower tube beam 310. Since the reinforcing rib 132 is a solid structure, riveting the C-pillar lower tube beam 310 to this reinforcing rib helps to firmly fix the C-pillar lower tube beam 310. Compared with the welding connection commonly used in this field, riveting connection is beneficial for quick disassembly. At the same time, riveting connection has less deformation, lower environmental requirements, good impact resistance, good seismic resistance, good fatigue resistance, and simple process equipment.

[0067] In one exemplary embodiment, the fixing part includes at least one connecting hole 150.

[0068] In this embodiment, the connecting hole 150 can be used to fix fasteners. Fasteners include, but are not limited to, rivets, screws, pins, and studs. When the fastener is a rivet, the connection adopts a riveting connection, which has small connection deformation, low environmental requirements, good impact resistance, good vibration resistance, good fatigue resistance, and simple process equipment.

[0069] In one exemplary embodiment, the C-pillar reinforcement 100 is a cast aluminum component.

[0070] This implementation method allows for the integral molding of cast aluminum parts, significantly reducing the manufacturing difficulty of the complex structure of the connector 100. Simultaneously, the high production efficiency and low cost of cast aluminum parts contribute to cost reduction. Cast aluminum parts also offer good shock resistance and wear resistance. Furthermore, their lightweight and high mechanical strength extend the service life of the connector 100 and reduce vehicle weight and energy consumption.

[0071] In one exemplary implementation, such as Figure 4 As shown, the upper part of the C-pillar includes: an upper reinforcing inner plate 220 and an upper tubular beam 210. The upper tubular beam 210 is fixedly connected to the upper reinforcing inner plate 220. The upper tubular beam 210 is connected to the second connecting part 120.

[0072] like Figure 4As shown, the lower part of the C-pillar includes: a lower reinforcing inner plate 320, a lower reinforcing outer plate 330, and a lower tube beam 310. The lower reinforcing inner plate 320 and the lower reinforcing outer plate 330 are fixedly connected, and the lower tube beam 310 is fixed between the lower reinforcing inner plate 320 and the lower reinforcing outer plate 330; and the lower tube beam 310 is connected to the third connecting part 130.

[0073] The sliding door center guide rail groove assembly includes a center guide rail groove outer plate 410, which is connected to the first connecting part 110.

[0074] Specifically, the C-pillar reinforcement 100 is connected to the upper C-pillar tube beam 210 at the top of the C-pillar via its second connecting part 120; and the C-pillar reinforcement 100 is connected to the lower C-pillar tube beam 310 at the bottom of the C-pillar via its third connecting part 130, thereby forming a continuous C-pillar structure.

[0075] In one example, the inner reinforcing panel 220 on the C-pillar and the body cover 600 (e.g.) Figure 5 (As shown) The C-pillar upper tube beam 210 is welded together to form a cavity for accommodating the C-pillar upper tube beam 210. The C-pillar upper tube beam 210 is riveted and fixed to the C-pillar reinforcement 100. The C-pillar upper tube beam 210 is also riveted and fixed to the C-pillar upper reinforcement inner plate 220. The C-pillar upper tube beam 210 can effectively enhance the structural strength of the upper part of the C-pillar, which is beneficial to improving the vehicle's collision score.

[0076] In one example, the lower C-pillar reinforcing inner panel 320 and the lower C-pillar reinforcing outer panel 330 are welded together to form a cavity accommodating the lower C-pillar tube beam 310. The lower C-pillar tube beam 310 is riveted to the C-pillar reinforcement 100. The lower C-pillar tube beam 310 is also riveted to the lower C-pillar reinforcing inner panel 320. The lower C-pillar tube beam 310 effectively enhances the structural strength of the lower part of the C-pillar, which is beneficial to improving the vehicle's crash test score.

[0077] In one example, the outer plate 410 of the central guide rail groove is riveted to the first connecting part 110.

[0078] Riveting connections result in minimal deformation, have low environmental requirements, offer good impact resistance, seismic resistance, fatigue resistance, and simple processing equipment.

[0079] In one exemplary embodiment, the upper reinforcing inner plate 220 and the lower reinforcing inner plate 320 of the C-pillar enclose a mounting groove, and the C-pillar reinforcement 100 is at least partially located in the mounting groove; the middle guide rail groove outer plate 410 is provided with a connecting recess 411, and the connecting recess 411 is fixedly connected to the first connecting portion 110.

[0080] The mounting groove provides installation space for the C-pillar reinforcement 100.

[0081] In one example, the connecting recess 411 is embedded in the cavity of the first connecting portion 110 and riveted to it. Two riveting holes 500 may be provided on the first side plate 112, the second side plate 113, the third side plate 114, and the fourth side plate 115. The two riveting holes 500 on the first side plate 112 may be distributed along the Z-direction of the vehicle body, and the two riveting holes 500 on the third side plate 114 may be distributed along the Y-direction of the vehicle body. This is because the Z-direction length of the third side plate 114 is shorter, and the third side plate 114 needs to be firmly fixed to the connecting recess 411; therefore, the two riveting holes 500 on the third side plate 114 may be distributed along the Y-direction of the vehicle body. The connecting plate 111 may have four riveting holes 500. The rivet holes 500 on the first side plate 112, the second side plate 113, the third side plate 114, the fourth side plate 115, and the connecting plate 111 are all used to fix the connecting recess 411 on the outer plate 410 of the middle guide rail groove, so that the C-pillar reinforcement 100 of the C-pillar and the outer plate 410 of the middle guide rail groove assembly of the sliding door are firmly fixed, so that the C-pillar reinforcement 100 provides good reinforcement for the middle guide rail groove assembly of the sliding door.

[0082] In one exemplary implementation, such as Figure 3 As shown, the upper C-pillar tube beam 210 extends upward to the top of the vehicle body; the lower C-pillar tube beam 310 extends downward to the bottom of the vehicle body.

[0083] In one example, the width of the upper C-pillar tube beam 210 and the lower C-pillar tube beam 310 is 20mm to 50mm, such as 20mm, 30mm, 40mm, 50mm, etc. The wall thickness of the upper C-pillar tube beam 210 and the lower C-pillar tube beam 310 is 2mm to 5mm, such as 2mm, 3mm, 4mm, 5mm, etc. This ensures that the upper C-pillar tube beam 210 and the lower C-pillar tube beam 310 have a good reinforcement effect while also taking into account their weight and processing costs. Of course, the width of the upper C-pillar tube beam 210 and the lower C-pillar tube beam 310 is not limited to the above ranges, nor is the wall thickness limited to the above ranges.

[0084] The upper tube beam 210 and the lower tube beam 310 of the C-pillar effectively enhance the strength and impact resistance of the C-pillar, thereby effectively improving the collision score.

[0085] In one exemplary implementation, such as Figure 3 As shown, the upper pipe beam 210 of the C-column has multiple riveting holes 500 along its length; the lower pipe beam 310 of the C-column has multiple riveting holes 500 along its length.

[0086] The upper C-column tube beam 210 is provided with a plurality of riveting holes 500 along its length direction, which is beneficial to the riveting and fixing of the upper C-column tube beam 210 and the upper C-column reinforcing inner panel 220.

[0087] The lower C-column tube beam 310 is provided with a plurality of riveting holes 500 along its length direction, which is beneficial to the riveting and fixing of the lower C-column tube beam 310 and the lower C-column reinforcing inner panel 320.

[0088] The riveting and fixing is beneficial to quick disassembly compared with the commonly used welding fixing in this field. At the same time, the riveting connection has small connection deformation, low environmental requirements, good impact resistance, seismic resistance, fatigue resistance and simple process equipment.

[0089] The embodiment of the present application also provides a vehicle (not shown in the figure), including the above-mentioned vehicle body. The vehicle provided by the embodiment of the present application connects the upper part 210 and the lower part of the C-column through the C-column reinforcing member 100, so as to form a continuous C-column structure, improve the modal and stiffness of the vehicle body, and then improve the collision score. In the use state, the continuous C-column structure can reduce the amplitude of the C-column and the vehicle body, thereby reducing the vibration noise.
