Description

Technical Field

[0001] The present invention relates to the technical field of automobile bodies, and in particular to a body-in-white side structure and an automobile. Background Art

[0002] With the development of the automobile industry, the industry and users expect the requirements for the collision safety of commercial vehicles to be further improved. The current cab can only meet the requirements of domestic passive safety regulations, but when dealing with higher speeds, such as 50km / h collisions, the cab strength is not enough, resulting in serious deformation of the cab, excessive intrusion into the passenger compartment and intrusion speed, which seriously affects the life safety of the occupants in the car. After studying safety accidents, practitioners found that the side panels have a great impact on the collision safety of the cab. In the event of a side collision, the B-pillar structure of the existing side panel structure is the main target. Due to the lack of an effective force transmission path, it can only be supported by the material strength of the B-pillar itself. The existing technical solution is only to add a high-strength steel reinforcement beam or reinforcement plate at the B-pillar. When a side collision occurs, especially a rollover, the impact force of the cab is large, the B-pillar strength and stiffness of the existing side panel structure are poor, and the body safety is low.

[0003] In the related art, high-strength steel is generally used to improve the structural strength, but the side panel outer panel does not have good support, and the overall strength and rigidity of the side panel is poor. When this structure collides or rolls, the B-pillar is hit hard, the force is difficult to transmit, and it is easy to fail. In addition, in order to meet the side collision safety of the B-pillar, it is necessary to add a large number of heavy reinforcement plates / beam structures. This structure is complex, the welding and assembly process is complicated, the dimensional accuracy is poor, the weight is heavy, the manufacturing cost is high, and it is not conducive to manufacturing economy and lightweight. Therefore, there is an urgent need to improve the structure of the existing automobile side sill. Summary of the invention

[0004] In the related art, a large number of heavier reinforcing plates / beams are used to enhance the overall strength of the body-in-white side structure, which results in complicated welding and assembly processes for the body-in-white manufacturing, poor dimensional accuracy, heavy weight and high manufacturing costs.

[0005] In a first aspect, an embodiment of the present application provides a body-in-white side panel structure, which includes:

[0006] The side door frame is connected to the B-pillar of the vehicle body;

[0007] A side outer panel is mounted on a side door frame, wherein a portion of the side outer panel overlaps with the B-pillar and the side door frame, one end of the side outer panel extends rearwardly along its transverse direction and is connected to the C-pillar and the rear wall of the vehicle body, and reinforcement areas are arranged at intervals along its transverse direction on the side outer panel.

[0008] In combination with the first aspect, in one embodiment, the reinforced area includes:

[0009] An upper reinforcement plate, which is installed above the top of the side door frame and the side window of the vehicle body;

[0010] A middle reinforcement plate installed between the side windows of the vehicle body and the tool box door opening;

[0011] A lower reinforcing plate is installed at the bottom end of the side door frame and below the tool box door opening.

[0012] In combination with the first aspect, in one embodiment, the thickness of the upper reinforcing plate, the middle reinforcing plate, and the lower reinforcing plate is between 1.5 times and 2 times the thickness of the side outer panel.

[0013] In combination with the first aspect, in one embodiment, reinforcing ribs are cross-arranged on the inner sides of the upper reinforcing plate, the middle reinforcing plate, and the lower reinforcing plate.

[0014] In combination with the first aspect, in one embodiment, the side door frame portion and the B-pillar are spaced apart to form a first cavity, the side outer panel portion and the side door frame are spaced apart to form a second cavity, and the first cavity at least partially corresponds to the position of the second cavity.

[0015] In combination with the first aspect, in one embodiment, it further includes: a side panel upper cross beam, which is used to connect to the A-pillar, B-pillar and C-pillar of the vehicle body.

[0016] In combination with the first aspect, in one embodiment, it further includes: a side panel upper joint, one side of which is connected to the side panel upper cross beam to clamp the C-pillar, and the other side is connected to the side panel outer panel.

[0017] In combination with the first aspect, in one embodiment, a side portion of the side enclosure upper joint is spaced apart from the side enclosure upper cross beam to form a third beam cavity, and another side portion is spaced apart from the side enclosure outer panel to form a fourth beam cavity.

[0018] In combination with the first aspect, in one implementation, the side outer panel is used to enclose a triangular beam cavity with the C-pillar.

[0020] The beneficial effects brought by the technical solution provided by the embodiment of the present application include at least:

[0021] The present application forms two vertical transmission paths by connecting the side panel with the B-pillar and the C-pillar to transfer the force of the side panel to the floor of the body-in-white. At the same time, by arranging a transverse reinforcement area on the side panel, the force is transferred to other structures of the body-in-white, such as the C-pillar, the rear panel, and the floor.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the related art, a large number of heavier reinforcing plates / beams are used to enhance the overall strength of the body-in-white side structure, which results in complicated welding and assembly processes for the body-in-white manufacturing, poor dimensional accuracy, heavy weight and high manufacturing costs.

[0033] First, as Figure 1 As shown, the present application provides a body-in-white side panel structure, which includes: a side panel door frame 1 and a side panel outer panel 3; wherein,

[0034] A side door frame 1 is connected to a B-pillar 2 of a vehicle body; a side outer panel 3 is mounted on the side door frame 1, wherein a portion of the side outer panel 3 overlaps with the B-pillar 2 and the side door frame 1, and one end of the side outer panel 3 extends rearwardly along its transverse direction and is connected to a C-pillar 4 and a rear wall of the vehicle body; and reinforcement areas are arranged at intervals along the transverse direction on the side outer panel 3.

[0035] It can be understood that the above-mentioned lateral direction refers to the front and rear direction of the vehicle body, and the vertical direction refers to the height direction of the vehicle body.

[0036] Optionally, the side outer panel 3 is made of non-metallic composite material and is formed by SMC or compression molding, and the other structures are made of metal materials such as steel or aluminum and are formed by stamping and bending. The side outer panel 3 is connected to the other structures by gluing.

[0037] Specifically, Figure 2 As shown, the three reinforcement areas include: an upper reinforcement plate 31, a middle reinforcement plate 32 and a lower reinforcement plate 33; wherein,

[0038] The upper reinforcing plate 31 is installed at the top of the side door frame 1 and above the side window 5 of the vehicle body; the middle reinforcing plate 32 is installed between the side window 5 of the vehicle body and the tool box door opening 6; the lower reinforcing plate 33 is installed at the bottom of the side door frame 1 and below the tool box door opening 6.

[0039] It is worth noting that the present application forms two vertical transmission paths by connecting the side panel with the B-pillar and the C-pillar to transfer the force of the side panel to the floor of the body-in-white. At the same time, three horizontal reinforcement plates are arranged on the side panel to transfer the force to other structures of the body-in-white, such as the C-pillar, the rear panel, and the floor. By forming two vertical paths and three horizontal paths, the whole body-in-white force is achieved.

[0040] In a first optional embodiment of the present application, the thickness of the upper reinforcing plate 31 , the middle reinforcing plate 32 , and the lower reinforcing plate 33 is between 1.5 times and 2 times the thickness of the side outer panel 3 .

[0041] It is worth mentioning that the upper reinforcing plate 31, the middle reinforcing plate 32 and the lower reinforcing plate 33 are key positions for supporting the structural strength of the body in white. Thickening in these areas can effectively improve the overall strength.

[0042] In the second optional embodiment of the present application, reinforcing ribs 35 are cross-arranged on the inner sides of the upper reinforcing plate 31, the middle reinforcing plate 32, and the lower reinforcing plate 33. Preferably, Figure 3 As shown, the reinforcing ribs 35 are arranged in a hexagon or a cross shape. Optionally, the reinforcing ribs 35 can also be arranged in a quadrilateral or a triangle.

[0043] It is worth noting that the support strength of the reinforcing rib 35 increases with the complexity of the structure. Furthermore, in the above embodiment, the upper reinforcing plate 31, the middle reinforcing plate 32 and the lower reinforcing plate 33 form three transverse reinforcing structures with the side outer panel 3, which solves the problem of insufficient rigidity caused by the large plane of the side outer panel 3. At the same time, when the side outer panel 3 is hit, the force is transmitted from the side outer panel to the support beam B-pillar 2 and C-pillar 4 through the structure, and then to other parts of the body-in-white such as the rear panel and the floor, effectively improving the structural strength. At the same time, different from steel plate parts with a single material thickness, by designing the material thickness and reinforcing ribs at different positions, the strength and rigidity of the outer panel structure are effectively improved, and lightweighting is achieved.

[0044] In some preferred implementations, Figure 4 As shown, the side door frame 1 is partially spaced from the B-pillar 2 to form a first cavity 11, the side outer panel 3 is partially spaced from the side door frame 1 to form a second cavity 34, and the first cavity 11 at least partially corresponds to the position of the second cavity 34.

[0045] It is worth noting that in the above embodiment, there are two layers of beam cavity structures (first cavity 11 and second cavity 34) in the cross section of the B-pillar 2 area. In the event of a collision (such as rollover, etc.), the side outer panel 3 made of non-metallic composite material is first crushed and plays an energy-absorbing role, while the beam cavity of the B-pillar 2 made of metal material plays a supporting role, and the structural strength of the B-pillar 2 itself is improved. In addition, the B-pillar 2 forms a vertical transmission path to transmit the force to other structures of the body-in-white such as the floor.

[0046] In some optional implementations, the side panel structure further includes: a side panel upper cross beam 8, which is used to connect to the A-pillar, the B-pillar 2 and the C-pillar 4 of the vehicle body.

[0047] It can be understood that the side panel upper cross beam 8 is used to transfer force to the C-pillar 4 and the rear panel of the body-in-white during a side collision.

[0048] Furthermore, the side enclosure structure further includes: a side enclosure upper joint 7 , one side of which is connected to the side enclosure upper cross beam 8 to clamp the C-pillar 4 , and the other side of which is connected to the side enclosure outer panel 3 .

[0049] Preferably, if Figure 6 and Figure 7As shown, one side portion of the side enclosure upper joint 7 is spaced apart from the side enclosure upper cross beam 8 to form a third beam cavity, and the other side portion is spaced apart from the side enclosure outer panel 3 to form a fourth beam cavity.

[0050] It is understandable that the two sides of the side panel upper joint 7 form a double beam cavity structure with the side panel outer panel 3 and the side panel upper cross beam 8. This structure effectively enhances the overall structural strength of the rear part of the side panel. In the event of a side collision, the beam cavity structure of the side panel upper joint 7 and the side panel upper cross beam 8 can play an additional supporting role, effectively protecting the living space at the rear of the cab. At the same time, the collision transmission path is optimized: when a side collision occurs, the force generated by the collision will be transmitted to the side panel upper joint 7 through the side panel upper cross beam 8, and then to the C-pillar 4 and the rear part of the body-in-white, rather than just the side panel B-pillar 2 as the main force-bearing member, thereby improving collision safety.

[0051] In some preferred implementations, Figure 5 As shown, the side outer panel 3 is used to form a triangular beam cavity with the C-pillar 4.

[0052] It is understandable that compared with the "J"-shaped structure, it is light in weight and reduces manufacturing costs. In addition, when the side outer panel 3 and the rear enclosure assembly are connected to form a complete body-in-white, a vertical transmission path is formed, and one side of the C-pillar 4 is connected to the rear enclosure through the side outer panel 3, which optimizes the transmission path. When a collision occurs, the C-pillar 4 transfers the force to the rear enclosure assembly, dispersing the force on the side enclosure and improving collision safety. In this way, the overall force transmission path optimization of the body-in-white side enclosure structure is completed: the transmission path includes three lateral paths (side enclosure upper cross beam 8 and side enclosure upper joint 7 and upper reinforcement plate 31, middle reinforcement plate 32, lower reinforcement plate 33) and two vertical paths (B-pillar 2, C-pillar 4).

[0053] In a second aspect, the present application provides a body-in-white, which includes: a body-in-white side panel structure, which includes: a side panel door frame 1 and a side panel outer panel 3; wherein,

[0054] A side door frame 1 is connected to a B-pillar 2 of a vehicle body; a side outer panel 3 is mounted on the side door frame 1, wherein a portion of the side outer panel 3 overlaps with the B-pillar 2 and the side door frame 1, and one end of the side outer panel 3 extends rearwardly along its transverse direction and is connected to a C-pillar 4 and a rear wall of the vehicle body; and reinforcement areas are arranged at intervals along the transverse direction on the side outer panel 3.

[0055] It can be understood that the above-mentioned lateral direction refers to the front and rear direction of the vehicle body, and the vertical direction refers to the height direction of the vehicle body.

[0056] Optionally, the side outer panel 3 is made of non-metallic composite material and is formed by SMC or compression molding, and the other structures are made of metal materials such as steel or aluminum and are formed by stamping and bending. The side outer panel 3 is connected to the other structures by gluing.

[0057] Specifically, Figure 2 As shown, the three reinforcement areas include: an upper reinforcement plate 31, a middle reinforcement plate 32 and a lower reinforcement plate 33; wherein,

[0058] The upper reinforcing plate 31 is installed at the top of the side door frame 1 and above the side window 5 of the vehicle body; the middle reinforcing plate 32 is installed between the side window 5 of the vehicle body and the tool box door opening 6; the lower reinforcing plate 33 is installed at the bottom of the side door frame 1 and below the tool box door opening 6.

[0059] It is worth noting that the present application forms two vertical transmission paths by connecting the side panel with the B-pillar and the C-pillar to transfer the force of the side panel to the floor of the body-in-white. At the same time, three horizontal reinforcement plates are arranged on the side panel to transfer the force to other structures of the body-in-white, such as the C-pillar, the rear panel, and the floor. By forming two vertical paths and three horizontal paths, the whole body-in-white force is achieved.

[0060] In the first optional embodiment of the present application, the thickness of the upper reinforcing plate 31 , the middle reinforcing plate 32 , and the lower reinforcing plate 33 is between 1.5 and 2.0 times the thickness of the side outer panel 3 .

[0061] It is worth mentioning that the positions of the upper reinforcing plate 31, the middle reinforcing plate 32 and the lower reinforcing plate 33 are key positions for supporting the structural strength of the body in white. Thickening in this area can effectively improve the overall strength.

[0062] In the second optional embodiment of the present application, reinforcing ribs 35 are cross-arranged on the inner sides of the upper reinforcing plate 31, the middle reinforcing plate 32, and the lower reinforcing plate 33. Preferably, Figure 3 As shown, the reinforcing ribs 35 are arranged in a hexagon or a cross shape. Optionally, the reinforcing ribs 35 can also be arranged in a quadrilateral or a triangle.

[0063] It is worth noting that the support strength of the reinforcing rib 35 increases with the complexity of the structure. Furthermore, in the above embodiment, the upper reinforcing plate 31, the middle reinforcing plate 32 and the lower reinforcing plate 33 form three transverse reinforcing structures with the side outer panel 3, which solves the problem of insufficient rigidity caused by the large plane of the side outer panel 3. At the same time, when the side outer panel 3 is hit, the force is transmitted from the side outer panel to the support beam B-pillar 2 and C-pillar 4 through the structure, and then to other parts of the body-in-white such as the rear panel and the floor, effectively improving the structural strength. At the same time, different from steel plate parts with a single material thickness, by designing the material thickness and reinforcing ribs at different positions, the strength and rigidity of the outer panel structure are effectively improved, and lightweighting is achieved.

[0064] In some preferred implementations, Figure 4As shown, the side door frame 1 is partially spaced from the B-pillar 2 to form a first cavity 11, the side outer panel 3 is partially spaced from the side door frame 1 to form a second cavity 34, and the first cavity 11 at least partially corresponds to the position of the second cavity 34.

[0065] It is worth noting that in the above embodiment, there are two layers of beam cavity structures (first cavity 11 and second cavity 34) in the cross section of the B-pillar 2 area. In the event of a collision (such as rollover, etc.), the side outer panel 3 made of non-metallic composite material is first crushed and plays an energy-absorbing role, while the beam cavity of the B-pillar 2 made of metal material plays a supporting role, and the structural strength of the B-pillar 2 itself is improved. In addition, the B-pillar 2 forms a vertical transmission path to transmit the force to other structures of the body-in-white such as the floor.

[0066] In some optional implementations, the side panel structure further includes: a side panel upper cross beam 8, which is used to connect to the A-pillar, the B-pillar 2 and the C-pillar 4 of the vehicle body.

[0067] It can be understood that the side panel upper cross beam 8 is used to transfer force to the C-pillar 4 and the rear panel of the body-in-white during a side collision.

[0068] Furthermore, the side enclosure structure further includes: a side enclosure upper joint 7 , one side of which is connected to the side enclosure upper cross beam 8 to clamp the C-pillar 4 , and the other side of which is connected to the side enclosure outer panel 3 .

[0069] Preferably, if Figure 6 and Figure 7 As shown, one side portion of the side enclosure upper joint 7 is spaced apart from the side enclosure upper cross beam 8 to form a third beam cavity, and the other side portion is spaced apart from the side enclosure outer panel 3 to form a fourth beam cavity.

[0070] It is understandable that the two sides of the side panel upper joint 7 form a double beam cavity structure with the side panel outer panel 3 and the side panel upper cross beam 8. This structure effectively enhances the overall structural strength of the rear part of the side panel.

At the same time, the collision transmission path is optimized: when a side collision occurs, the force generated by the collision will be transmitted to the side panel upper joint 7 through the side panel upper cross beam 8, and then to the C-pillar 4 and the rear part of the body-in-white, rather than just the side panel B-pillar 2 as the main force-bearing member, thereby improving collision safety.

[0071] In some preferred implementations, Figure 5 As shown, the side outer panel 3 is used to form a triangular beam cavity with the C-pillar 4.

[0072] It is understandable that compared with the "J"-shaped structure, it is light in weight and reduces manufacturing costs. In addition, when the side outer panel 3 and the rear enclosure assembly are connected to form a complete body-in-white, a vertical transmission path is formed, and one side of the C-pillar 4 is connected to the rear enclosure through the side outer panel 3, which optimizes the transmission path. When a collision occurs, the C-pillar 4 transfers the force to the rear enclosure assembly, dispersing the force on the side enclosure and improving collision safety. In this way, the overall force transmission path optimization of the body-in-white side enclosure structure is completed: the transmission path includes three lateral paths (side enclosure upper cross beam 8 and side enclosure upper joint 7 and upper reinforcement plate 31, middle reinforcement plate 32, lower reinforcement plate 33) and two vertical paths (B-pillar 2, C-pillar 4).

[0073] In a third aspect, the present application provides a car, which includes: a body-in-white side panel structure, which includes: a side panel door frame 1 and a side panel outer panel 3; wherein:

[0074] A side door frame 1 is connected to a B-pillar 2 of a vehicle body; a side outer panel 3 is mounted on the side door frame 1, wherein a portion of the side outer panel 3 overlaps with the B-pillar 2 and the side door frame 1, and one end of the side outer panel 3 extends rearwardly along its transverse direction and is connected to a C-pillar 4 and a rear wall of the vehicle body; and reinforcement areas are arranged at intervals along the transverse direction on the side outer panel 3.

[0075] It can be understood that the above-mentioned lateral direction refers to the front and rear direction of the vehicle body, and the vertical direction refers to the height direction of the vehicle body.

[0081] It is worth mentioning that the positions of the upper reinforcing plate 31, the middle reinforcing plate 32 and the lower reinforcing plate 33 are key positions for supporting the structural strength of the body in white. Thickening in this area can effectively improve the overall strength.

[0082] In the second optional embodiment of the present application, reinforcing ribs 35 are cross-arranged on the inner sides of the upper reinforcing plate 31, the middle reinforcing plate 32, and the lower reinforcing plate 33. Preferably, Figure 3 As shown, the reinforcing ribs 35 are arranged in a hexagon or a cross shape. Optionally, the reinforcing ribs 35 can also be arranged in a quadrilateral or a triangle.

[0086] In some optional implementations, the side panel structure further includes: a side panel upper cross beam 8, which is used to connect to the A-pillar, the B-pillar 2 and the C-pillar 4 of the vehicle body.

[0087] It can be understood that the side panel upper cross beam 8 is used to transfer force to the C-pillar 4 and the rear panel of the body-in-white during a side collision.

[0088] Furthermore, the side enclosure structure further includes: a side enclosure upper joint 7 , one side of which is connected to the side enclosure upper cross beam 8 to clamp the C-pillar 4 , and the other side of which is connected to the side enclosure outer panel 3 .

[0089] Preferably, if Figure 6 and Figure 7 As shown, one side portion of the side enclosure upper joint 7 is spaced apart from the side enclosure upper cross beam 8 to form a third beam cavity, and the other side portion is spaced apart from the side enclosure outer panel 3 to form a fourth beam cavity.

[0090] It is understandable that the two sides of the side panel upper joint 7 form a double beam cavity structure with the side panel outer panel 3 and the side panel upper cross beam 8.

In this way, the overall force transmission path optimization of the body-in-white side enclosure structure is completed: the transmission path includes three lateral paths (side enclosure upper cross beam 8 and side enclosure upper joint 7 and upper reinforcement plate 31, middle reinforcement plate 32, lower reinforcement plate 33) and two vertical paths (B-pillar 2, C-pillar 4).

[0093] In summary, the present invention adopts non-metallic composite materials, which are different from steel plates with a single material thickness. By designing the material thickness and reinforcing ribs at different positions, the strength and rigidity of the outer plate structure are effectively improved, and lightweight is achieved. At the same time, three lateral transmission paths are established to transfer the force to other structures of the body-in-white such as the C-pillar, the rear enclosure, and the floor. Furthermore, in the present application, the B-pillar and the side enclosure outer panel form a double beam cavity structure, an energy absorption structure is formed on the outside, and the structural strength is improved on the inside, which effectively improves the collision energy absorption performance of the B-pillar. The B-pillar forms a vertical transmission path to transfer the force to other structures of the body-in-white such as the floor. In addition, the side enclosure outer panel and the C-pillar form a triangular beam cavity, forming a vertical transmission path to transfer the force to other structures of the body-in-white such as the rear enclosure. At the same time, the process is simple, lightweight is achieved, and production costs are reduced. At the same time, the upper crossbeam of the side enclosure is connected to the upper joint of the side enclosure, and the upper joint is connected to the upper part of the C-pillar to form a double beam cavity structure, while optimizing the force transmission path of the side enclosure and improving the side enclosure collision safety. Finally, after adopting the above optimization measures, the side panel assembly as a whole can achieve the effect of optimizing the transmission path during collision, forming two vertical paths and three horizontal paths, so as to realize the overall force of the body in white. While not increasing the number of parts, simplifying the welding process, and achieving lightweight, the passive safety of the side panel in side collision is improved.
