[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described 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 those skilled in the art without creative work are within the scope of protection of the present application.

[0062] According to a first aspect of the present application, a side panel structure 10 is provided for connecting a roof structure. Figure 1 and Figure 2 The roof structure includes: a side outer panel 110 and a force transfer member 120.

[0063] The side panel 110 is connected to the roof structure to receive at least part of the static pressure on the roof structure. The force transfer member 120 is connected to the side panel 110 to transfer the static pressure received by the side panel 110 .

[0064] A force transfer member 120 is provided at least at a position of the side panel structure 10 close to the roof structure.

[0065] Through the above technical solution, a force transfer member 120 is set at a position close to the roof of the side panel structure 10, and the force transfer member 120 is used to transfer the static pressure received by the side panel outer panel 110, thereby optimizing the transmission path of the static pressure and further improving the pressure-bearing capacity of the roof structure, thereby improving the safety performance of the vehicle body structure.

[0066] Moreover, compared with the side panel structure 10 in the prior art, the side panel structure 10 of the present application has only one force transfer member 120 provided near the roof, which can be realized by utilizing the space of the original side panel structure 10, and the static pressure bearing capacity of the roof can be improved without additional material addition, which is convenient for design and manufacturing. Force can be transmitted in multiple directions instead of being concentrated on a single path. Multi-path transmission helps to reduce stress concentration on a single structural component.

[0067] In some embodiments, reference Figure 1 The side panel structure 10 further includes a force support member 130 .

[0068] The force support 130 is used to receive at least part of the static pressure transmitted from the side outer panel 110 , wherein the force transfer member 120 is connected between the side outer panel 110 and the force support to transfer the static pressure received by the side outer panel 110 to the force support 130 .

[0069] By setting a force support member 130 to be connected with the force transfer member 120, the static pressure received by the side outer panel 110 is transferred to the force support member 130 by utilizing the force transfer member 120, thereby forming a force transmission path of the roof structure-side outer panel 110-force transfer member 120-force support member 130, thereby achieving uniform distribution of force in multiple directions, further improving the pressure-bearing capacity of the overall structure and increasing the critical load capacity of the side structure 10.

[0070] For example, the force support member 130 may be fixedly arranged, for example, fixedly arranged on the side panel 110 , which can further improve the overall stability of the side panel structure 10 .

[0071] In some embodiments, reference Figures 2 to 5 The side panel outer panel 110 includes a first type outer panel 111 and a second type outer panel 112 . The side panel structure 10 also includes a first type force transfer member 140 and a first type force support member 150 .

[0072] The first type of outer panel 111 is used to connect the roof structure at the first side S1 of the roof structure, the second type of outer panel 112 is used to connect the roof structure at the second side S2 of the roof structure, the first type of force transfer member 140 is connected to the first type of outer panel 111 near the roof structure, and the first type of force support member 150 is connected between the first type of force transfer member 140 and the second type of outer panel 112.

[0073] Among them, the first side S1 and the second side S2 are arranged opposite to each other, and the first type of outer panel 111 and the second type of outer panel 112 are arranged at an angle, and the first type of outer panel 111, the first type of force transfer member 140, the first type of force support member 150 and the second type of outer panel 112 are connected end to end in sequence to form a first closed structure.

[0074] By setting a first type of force transfer member 140 and a first type of force support member 150 to be connected between the first type of outer panel 111 and the second type of outer panel 112, and connecting them end to end in sequence to form a first closed structure, the first closed structure formed by each component can further optimize the force transmission path.

[0075] Exemplarily, the first closed structure is a closed ring design. When a collision occurs, the closed ring design structure can better withstand and disperse the impact force, resist bending and twisting deformation, and thus protect the integrity of the vehicle body structure.

[0076] It should be noted that the first type of outer panel 111 in this application is the A-pillar outer panel of the A-pillar assembly, and the second type of outer panel 112 is the B-pillar outer panel of the B-pillar assembly. The A-pillar outer panel and the B-pillar outer panel are connected at a position close to the roof structure, that is, the upper section of the A-pillar outer panel is connected to the upper section of the B-pillar.

[0077] This method of distributing static pressure reduces structural deformation caused by local overloads, especially at the junction of the A-pillar and the front windshield, which is the most vulnerable part of the roof structure.

[0078] In some embodiments, reference Figures 2 to 5 , the cross-section of the first closed structure is triangular.

[0079] By designing the cross-section of the first closed structure as a triangle, compared with other shapes (such as a quadrilateral), the triangular structure can disperse the impact force acting on one point to three sides and three vertices. This dispersion effect can reduce the pressure on a single point, thereby reducing local deformation and damage, and thus making the side structure 10 have higher bending and torsional resistance, which can better support the roof and body, prevent serious deformation of the body, and protect the safety of the occupants. The triangular structure can maintain its shape and strength when under pressure, avoiding the front windshield from being broken.

[0080] In some embodiments, reference Figures 2 to 5 The cross-section of the first closed structure is a right triangle; wherein the first type of force support member 150 and the second type of outer panel 112 are arranged vertically.

[0081] By setting the cross-section of the first closed structure to be a right-angled triangle, and setting the first type of force support member 150 and the second type of outer panel 112 vertically, the use of a right-angled triangle structure can achieve the effect of lightweighting the vehicle body. On the premise of meeting requirements such as strength, the use of a right-angled triangle structure can greatly reduce the weight of the vehicle body, thereby improving fuel efficiency and performance.

[0082] In some embodiments, reference Figures 2 to 5 The first type of force transfer member 140 and the first type of force support member 150 are integrally formed.

[0083] By integrally forming the first type force transfer member 140 and the first type force support member 150 , the number of weld points of the side panel structure 10 as a whole can be reduced, so that the side panel structure 10 has higher strength and the torsional rigidity of the vehicle body is improved.

[0084] In the present application, the first type of force transfer member 140 and the first type of force support member 150 may also be integrally formed with the first type of support plate.

[0085] In some embodiments, reference Figures 2 to 5 The first type of force transfer member 140 and the first type of force support member 150 are columnar structures.

[0086] By arranging the first type force transfer member 140 and the first type force support member 150 in a columnar structure, the connection with the first type outer panel 111 and the second type outer panel 112 is facilitated.

[0087] For example, the columnar first-class force transfer member 140 can be welded to the first-class outer panel 111, and the first-class force support member 150 can be welded to the second-class outer panel 112, while the first-class force transfer member 140 and the first-class force support member 150 are integrally formed in a columnar shape, which can facilitate the forming of the first-class force transfer member 140 and the first-class force support member 150.

[0088] In some embodiments, reference Figures 2 to 5 The side panel structure 10 further includes: a second type of force transfer member 160 and a second type of force support member 170 .

[0089] The second type of force transfer member 160 is connected to the first type of outer panel 111 at a position away from the roof structure relative to the first type of force transfer member 140, and the second type of force support member 170 is connected between the second type of force transfer member 160 and the first type of outer panel 111, wherein the first type of outer panel 111 and the second type of force transfer member 160 and the second type of force support member 170 are connected end to end in sequence to form a second closed structure.

[0090] By arranging a second type of force transfer member 160 at a position away from the roof structure relative to the first type of force transfer member 140, and the second type of force transfer member 160 is connected to the first type of outer panel 111, the second type of force support member 170 is connected between the second type of force transfer member 160 and the first type of outer panel 111, so that the first type of outer panel 111 and the second type of force transfer member 160 and the second type of force support member 170 are connected end to end in sequence to form a second closed structure, further improving the force transmission path of the second area of ​​the side panel structure 10, avoiding excessive stress concentration, and improving the overall pressure-bearing capacity of the side panel structure 10.

[0091] In some embodiments, reference Figures 2 to 5 , the cross-section of the second closed structure is triangular.

[0092] By setting the cross-section of the second closed structure to be triangular, compared with other shapes (such as a quadrilateral), the triangular structure can disperse the impact force acting on one point to three sides and three vertices. This dispersion effect can reduce the pressure on a single point, thereby reducing local deformation and damage, and thus making the side structure 10 have higher bending and torsional resistance, which can better support the roof and body, prevent serious deformation of the body, and protect the safety of the occupants.

[0093] The second closing structure can be used in conjunction with the first closing structure to improve the force transmission path of different areas of the side frame structure 10.

[0094] In some embodiments, reference Figures 2 to 5 , the cross-section of the second closed structure is a right triangle.

[0095] By setting the cross-section of the second closed structure into a right-angled triangle, the use of a right-angled triangle structure can achieve the effect of lightweighting the vehicle body. On the premise of meeting requirements such as strength, the use of a right-angled triangle structure can greatly reduce the weight of the vehicle body, thereby improving fuel efficiency and performance.

[0096] In some embodiments, the cross-sectional area of ​​the first closed structure is smaller than the cross-sectional area of ​​the second closed structure.

[0097] By setting the cross-sectional area of ​​the first closed structure to be smaller than the cross-sectional area of ​​the second closed structure, it is possible to avoid occupying too much space on the entire side panel structure 10. While ensuring the pressure-bearing capacity of the side panel structure 10, a certain amount of space can also be left for the door frame opened on the side panel structure 10.

[0098] In some embodiments, reference Figure 4 The second type of force support member 170 has a right-angle bending structure 171; wherein the right-angle bending structure 171 is arranged relative to the first type of outer panel 111.

[0099] By setting the second type of force support member 170 as a support member with a right-angle bending structure 171, and the right-angle bending structure 171 is set relative to the first type of outer panel 111, it is possible to form a right-angle shape only by the second type of force support member 170, so that the second type of force support member 170, the second type of force transfer member 160 and the first type of outer panel 111 can form a triangular second closed structure.

[0100] For example, part of the second-type force support member 170 can be connected to the first-type outer panel 111 by avoiding the first-type force transfer member 140. At this time, part of the second-type force support member 170 can be part of the first-type outer panel 111. The overall performance of the side panel structure 10 under this structure is stable and the safety performance is better.

[0101] Transparent window glass can be installed at the position of the second type of closed structure, which can ensure the strength of the side structure 10 while also widening the passenger's observation field of view.

[0102] In some embodiments, reference Figure 6 The side panel structure 10 further includes an outer decorative panel 180 and an inner connecting panel 190 .

[0103] The inner connecting plate 190 is located between the outer decorative panel 180 and the second type outer panel 112 , and at least one weight-reducing hole is defined on the inner connecting plate 190 .

[0104] By setting the inner connecting plate 190 between the outer panel 180 and the second type of outer panel 112, at least one weight-reducing hole can be opened on the inner connecting plate 190. Compared with the solid connecting plate in the prior art, the setting of the weight-reducing hole can reduce the weight of the structure while enhancing the stability and durability of the structure.

[0105] For example, the inner connecting plate 190 and the second type outer panel 112 may be bonded together, and the stability and durability of the side panel structure 10 may be further enhanced by bonding.

[0106] It should be noted that the bonding method can also be replaced by welding or mechanical fastening, and the specific method is applied according to the actual manufacturing cost and convenience of maintenance.

[0107] The force transfer member and the force support member in the present application can be made of high-strength steel, aluminum alloy or carbon fiber composite material to achieve a better strength-to-weight ratio.

[0108] In some embodiments, reference Figure 6 The side panel structure 10 further includes: a third type of support member 210 .

[0109] The third type support member 210 is connected between the outer trim panel 180 and the inner connection panel 190 .

[0110] By arranging the third type of support member 210 between the outer trim panel 180 and the inner connecting panel 190 , the third type of support member 210 can further provide a support point, thereby distributing the static pressure on the roof structure to a wider area.

[0111] For example, the third type of support member 210 can be bonded to the exterior panel 180 and the inner connection panel 190 by bonding, or can be welded, which is not limited here.

[0112] In this application, in order to leave more space for the door frame opened on the side structure 10, the connection between the second type of force support member 170 and the first type of outer panel 111 and the connection between the first type of force transfer member 140 and the first type of outer panel 111 can be spaced apart.

[0113] Of course, without considering leaving more space for the door frame opened on the side structure 10, the connection between the second type of force support member 170 and the first type of outer panel 111 and the connection between the first type of force transfer member 140 and the first type of outer panel 111 can be set without spacing, but they cannot be crossed.

[0114] According to a second aspect of the present application, a vehicle body assembly is provided, comprising the side panel structure 10 as described above.

[0115] The vehicle body assembly of the present application includes the above-mentioned side panel structure 10 , and thus has all the beneficial effects of the above-mentioned side panel structure 10 .

[0116] According to the third aspect of this application, reference Figure 7 , a vehicle 1 is also provided, comprising the above side structure 10 or the above body assembly.

[0117] The vehicle 1 of the present application includes the above-mentioned side panel structure 10 , and thus has all the beneficial effects of the above-mentioned side panel structure 10 .

[0118] The vehicle 1 of the present application includes the above-mentioned body assembly, and therefore has all the beneficial effects of the above-mentioned body assembly.

[0119] The vehicle 1 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation on this.

[0120] The side panel structure 10 of the present application can be applied to vehicles 1 of various sizes and types, including sedans, SUVs, trucks, etc. By adjusting the size and shape of the two closed structures of the side panel structure 10, it can be easily adapted to the design requirements of different vehicles 1. It can even be applied to electric vehicles and autonomous vehicles 1 to meet their unique structural strength requirements.
