[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The embodiment of the present application provides a vehicle side roof system, which can solve the technical problem in the related art of enhancing the rigidity of the side roof. In the event of a collision, the side roof may be deformed or broken due to the excessive rigidity of the bracket.

[0037] See also Figure 1 and Figure 6 As shown, a vehicle side roof system provided by an embodiment of the present application may include: a side roof body 1; a reinforcing bracket 2, the reinforcing bracket 2 including an energy absorbing section 23 and a first fixed section 21 and a second fixed section 22 respectively connected to the two ends of the energy absorbing section 23, the first fixed section 21 and the second fixed section 22 are both installed on the inner side of the side roof body 1, the energy absorbing sections 23 are arranged at intervals in the side roof body 1, and the energy absorbing sections 23 are provided with energy absorbing holes 231; a bracket structure 3, the two ends of the bracket structure 3 are respectively fixed to the energy absorbing sections 23, and the bracket structure 3 protrudes toward a side close to the side roof body 1 to form a raised section 31, the raised section 31 is opposite to the energy absorbing hole 231, and one side of the raised section 31 is connected to the inner wall of the side roof body 1. The energy absorbing section 23 may extend substantially along the height direction of the vehicle, and the energy absorbing hole 231 may also extend along the height direction of the vehicle. In addition to cooperating with the raised section 31 to absorb energy, the energy absorbing hole 231 may also play a role in reducing weight.

[0038] The embodiment of the present application connects one side of the raised section 31 to the inner wall of the side roof cover body 1. In the normal state of the vehicle, the raised section 31 can support the side roof cover body 1 and improve its rigidity. The first fixing section 21 and the second fixing section 22 are fixed to the side roof cover body 1, so that the energy absorbing section 23 can be spaced apart from the side roof cover. The spacing can refer to the spacing along the Y direction of the vehicle (i.e., the transverse direction of the vehicle). The bracket structure 3 is fixed to the energy absorbing section 23, and the raised section 31 is opposite the energy absorbing hole 231. When the side roof cover is hit, the side roof cover body 1 can drive the raised section 31 to move toward the side close to the energy absorbing hole 231. The raised section 31 can collapse and absorb energy during this process. When the displacement is large, the raised section 31 can even overlap with the energy absorbing hole 231. At this time, it can not only collapse and absorb energy, but also enhance the supporting performance of the reinforced bracket 2 and reduce the possibility of the bracket breaking. This solves the technical problem in the related art that the side roof cover may be deformed or broken due to excessive rigidity.

[0039] See also Figure 2 As shown, in some optional embodiments, the raised section 31 may include a collapse section 311, and the two ends of the collapse section 311 are respectively connected to a first connecting section 312 and a second connecting section 313; the first connecting section 312 is connected to a first stabilizing section 32 on a side away from the collapse section 311, and the end of the first stabilizing section 32 away from the first connecting section 312 is fixed to the reinforcing bracket 2 near the energy absorbing hole 231, and the first connecting section 312 extends roughly along an extension direction perpendicular to the collapse section 311; the second connecting section 313 is connected to a second stabilizing section 33 on a side away from the collapse section 311, and the end of the second stabilizing section 33 away from the second connecting section 313 is also fixed to the reinforcing bracket 2 near the energy absorbing hole 231, and the second connecting section 313 extends obliquely from the connection with the second stabilizing section 33 toward the side close to the collapse section 311. The collapse section 311 can be directly connected to the first connecting section 312 and the second connecting section 313, or it can be indirectly connected. In the embodiment of the present application, the first stabilizing section 32 and the second stabilizing section 33 are respectively fixed to opposite sides of the energy absorbing hole 231, and the first stabilizing section 32 and the second stabilizing section 33 can each have a certain length to increase their respective contact surfaces with the energy absorbing section 23 and enhance the stability of the connection. Preferably, the distance between the first stabilizing section 32 and the second stabilizing section 33 can be greater than the length of the energy absorbing hole 231, so that the energy absorbing hole 231 formed by the support structure 3 and the energy absorbing section 23 is a stepped hole, which can enhance the supporting strength of the support structure 3 and the energy absorbing section 23. In some other embodiments, the length of the energy absorbing hole 231 can also be equal to or slightly greater than the distance between the first stabilizing section 32 and the second stabilizing section 33.

[0040] See also Figure 3As shown, further, the first connecting section 312 extends substantially perpendicular to the extension direction of the crushing section 311. That is, the first connecting section 312 can be perpendicular to the crushing section 311. The first connecting section 312 can also have a small angle with the crushing section 311, which can be a negative angle. The specific angle can be adjusted based on the crushing effect and the comprehensive consideration of the part's molding process. In addition, the second connecting section 313 extends obliquely from the connection with the second stabilizing section 33 toward the side close to the crushing section 311. The angle between the second connecting section 313 and the crushing section 311 can be acute or obtuse. Figure 4 As shown, the second connecting section 313 and the collapsing section 311 form an obtuse angle, and the angle formed by the second connecting section 313 and a section of the energy absorbing section 23 away from the second stabilizing section 33 is an acute angle. This arrangement allows the support structure 3 to collapse and deform toward one side of the first connecting section 312 when the entire structure collapses. Figure 5 As shown in the figure, the dotted line represents a schematic diagram of the structure of the support structure 3 after collapse, and the corresponding line represents a schematic diagram of the structure of the support structure 3 before collapse. Preferably, the length of the second connecting segment 313 is greater than the length of the first connecting segment 312. Specifically, the length of the second connecting segment 313 is greater than or equal to 1.5 times the length of the first connecting segment 312. This further ensures that when the support structure 3 is collapsed as a whole, the extrusion normal can be directed toward one side of the first connecting segment 312.

[0041] In some optional embodiments, the first stabilizing section 32 and the first connecting section 312 are connected by a first arc section 314, and first collapse notches 3141 are provided on both sides of the first arc section 314, and the first arc section 314 is provided with a first collapse hole 3142, and the first collapse hole 3142 is located between the first collapse notches 3141 on both sides; a second arc section 315 is connected between the first connecting section 312 and the collapse section 311, and second collapse notches 3151 are provided on both sides of the second arc section 315, and the second arc section 315 is provided with a second collapse hole 3152, and the second collapse hole 3152 is located between the second collapse notches 3151 on both sides. The first arc segment 314 connects the first stabilizing section 32 and the first connecting section 312, and the second arc segment 315 connects the first connecting section 312 and the collapsing section 311, both of which can improve the strength and stability of the connection, that is, the supporting performance of the bracket structure 3 on the side top cover body 1 can be improved, and when the bracket structure 3 is hit on the side top cover body 1 and the bracket structure 3 is compressed, it can also provide better buffering performance and reduce the possibility of breakage at the connection between the first stabilizing section 32 and the first connecting section 312 and the connection between the first connecting section 312 and the collapsing section 311. Furthermore, the first arc segment 314 can have two first collapse notches 3141, and the two first collapse notches 3141 and the first collapse hole 3142 can be spaced apart along the extension direction perpendicular to the collapse segment 311. The second arc segment 315 also has two second collapse notches 3151 at this time, and the two second collapse notches 3151 and the second collapse hole 3152 are also spaced apart along the extension direction perpendicular to the collapse segment 311. When the collapse segment 311 is squeezed and moves toward the side close to the energy absorption hole 231, the first connecting segment 312 is also gradually compressed and deformed. The provision of the first collapse notch 3141, the first collapse hole 3142, the second collapse notch 3151 and the second collapse hole 3152 can further make the deformation process smoother, enhance the collapse energy absorption capacity of the support structure 3, and reduce the possibility of the reinforcing bracket 2 breaking during the side top cover back impact. In some other embodiments, arc segments may also be provided at the connection between the second connecting segment 313 and the collapsing segment 311 , and at the connection between the second connecting segment 313 and the second stabilizing segment 33 .

[0042] In some optional embodiments, the first connecting section 312 is equipped with a first reinforcing rib 3121, which extends in a direction perpendicular to the spacing between the energy absorbing section 23 and the crushing section 311. The second connecting section 313 is equipped with a second reinforcing rib 3131, which extends in the arrangement direction of the second connecting section 313 and the crushing section 311. That is, the first reinforcing rib 3121 can extend in the extension direction of the first connecting section 312, and the second reinforcing rib 3131 can also extend in the extension direction of the second connecting section 313. Preferably, the first reinforcing rib 3121 and the second reinforcing rib 3131 are respectively provided in the middle of the first connecting section 312 and the second connecting section 313. The middle can be a middle position perpendicular to the arrangement direction of the second connecting section 313 and the crushing section 311, or can be another position slightly offset from the middle position. By respectively arranging the first reinforcing rib 3121 and the second reinforcing rib 3131 on the first connecting section 312 and the second connecting section 313, the supporting rigidity of the first connecting section 312 and the second connecting section 313 can be enhanced. The first connecting section 312 and the second connecting section 313 and the crushing section 311 can jointly support the side top cover body 1. When the side top cover body 1 of the vehicle is subjected to a slight impact, the risk of deformation of the side top cover body 1 can be significantly reduced.

[0043] In some optional embodiments, the crush section 311 is provided with a plurality of shock-absorbing grooves 3111 spaced apart along its extension direction. Each of the shock-absorbing grooves 3111 is filled with shock-absorbing adhesive 4, which is sandwiched between the shock-absorbing groove 3111 and the side cover body 1. The shock-absorbing grooves 3111 can be formed by recessing a portion of the crush section 311 toward a side away from the side cover body 1. Each of the shock-absorbing grooves 3111 can be filled with shock-absorbing adhesive. The shock-absorbing adhesive is applied to the shock-absorbing groove 3111 and expands after drying to connect with the inner wall of the side cover body 1. In this case, the crush section 311 can have a certain gap between it and the side cover body 1 due to the support of the shock-absorbing adhesive. The shock-absorbing adhesive has a certain degree of support rigidity and can also absorb some of the energy generated by the side cover during an impact. In this embodiment of the present application, the elastic and viscous properties of the shock-absorbing adhesive 4 can mitigate the impact force of an impact, providing a certain buffering effect, protecting the side cover body 1 and other structures surrounding the side cover body 1 and reducing the possibility of damage.

[0044] In some optional embodiments, the vehicle side roof system may further include: a cross-beam 5 mounted on the side roof body 1, a first fixing section 21 connected to the cross-beam 5, and the first fixing section 21 is connected to the side roof body 1; a side panel inner upper crossbeam 6, the side panel inner upper crossbeam 6 being connected to a side panel B-pillar inner panel 7, and a second fixing section 22 connected to the side panel inner upper crossbeam 6 and fixed to the side panel B-pillar inner panel 7. It should be understood that the first fixing section 21, the second fixing section 22, and the energy absorbing section 23 may be integrally formed or manufactured separately and then welded together. In an embodiment of the present application, one end of the first fixed section 21 can be connected to the cross beam 5 to support the first fixed section 21 through the cross beam 5, and the other end is fixed to the energy absorbing section 23, and the first fixed section 21 can extend along the Y direction of the vehicle, and part of the top surface of the first fixed section 21 is in contact with the side top cover body 1, so that the first fixed section 21 can play a role in supporting the side top cover body 1 and enhance the supporting strength of the side top cover body 1. One end of the second fixed section 22 is connected to the energy absorbing section 23, and the other end is connected to the side panel inner upper cross beam 6, so that the second fixed section 22 is fixed under the action of the side panel inner upper cross beam 6. Since the side panel B-pillar inner panel 7 is fixed to the side panel inner upper cross beam 6, the second fixed section 22 can be connected to the side panel B-pillar inner panel 7 to increase the connection point of the second fixed section 22 and enhance the connection stability of the second fixed section 22. In addition, the energy absorbing section 23 can also be partially connected to the side panel B-pillar inner panel 7. Furthermore, the part of the second fixed section 22 away from the side panel inner upper cross beam 6 can also be connected to the inner wall of the side top cover body 1. By connecting the first fixing section 21 to the cross member 5 and the second fixing section 22 to the side panel inner upper cross member 6, the force applied to the energy-absorbing section 23 can be transmitted to the cross member 5 and the side panel inner upper cross member 6 via the first fixing section 21 and the second fixing section 22, respectively. This effectively disperses the force, reduces the concentration of force on the energy-absorbing section 23, and reduces the possibility of damage to the energy-absorbing section 23. Furthermore, by distributing the force applied to the energy-absorbing section 23 to the cross member 5 and the side panel inner upper cross member 6, vehicle body materials can be more efficiently utilized, avoiding waste and excessive use of materials.

[0045] In some optional embodiments, the vehicle side roof system further includes a side panel outer upper crossbeam 8, the side panel outer upper crossbeam 8 being connected to the side panel inner upper crossbeam 6, and the side panel outer upper crossbeam 8 and the second fixing section 22 being spaced apart along the Z-direction of the vehicle. The side panel outer upper crossbeam 8 may include a flange structure and a beam body connected to the flange, the flange of the side panel outer upper crossbeam 8 being connected to the side panel inner upper crossbeam 6, and the beam body of the side panel outer upper crossbeam 8 being spaced apart from the second fixing section 22 along the Z-direction of the vehicle. This spacing may serve as an installation tolerance gap between the second fixing section 22 and the side panel outer upper crossbeam 8, thereby reducing the possibility of interference between the second fixing section 22 and the beam body of the side panel outer upper crossbeam 8, and also providing a certain amount of movement buffer space for the second fixing section 22 when a collision occurs at some parts of the top of the vehicle.

[0046] In some optional embodiments, the first fixing section 21 and the cross beam 5 are fixed by a first connecting bracket 91 and a second connecting bracket. The first connecting bracket 91 is fixed to the cross beam 5 and is sandwiched between the side roof body 1 and the first fixing section 21. The second connecting bracket is also fixed to the cross beam 5 and fixed to the first fixing section 21, and the second connecting bracket is installed on the side of the first fixing section 21 away from the first connecting bracket 91. In other words, the first fixing section 21 is fixed to the cross beam 5 at the end of the first fixing section 21 near the cross beam 5 by the first connecting bracket 91 and the second connecting bracket fixed to the cross beam 5, with the second connecting bracket spaced apart. By installing the first connecting bracket 91 and the second connecting bracket, the first fixing section 21 can be fixed by welding, thereby enhancing the stability of the connection. Since the side roof body 1 is relatively thin, the contact portion with the first fixing section 21 can be connected by bonding, which not only ensures the tightness of the connection but also effectively avoids connection failure caused by insufficient material thickness.

[0047] See also Figure 7 and Figure 8As shown, in some optional embodiments, the cross-sections of the first fixing segment 21, the second fixing segment 22, and the energy absorption segment 23 are all in a "Ji" shape. The first fixing segment 21, the second fixing segment 22, and the energy absorption segment 23 all include a top panel 24 and side panels 25 fixed to opposite sides of the top panel 24. The side panels 25 all extend along a direction perpendicular to the extension direction of the top panel 24, and the side panels 25 and the top panel 24 enclose a strengthening cavity 27. In addition, a flap 26 is fixed to one side of each side panel 25 away from the top panel 24. The second connecting bracket includes a fixed beam segment 921 and a strengthening segment 922 connected to the fixed beam segment 921. The fixed beam segment 921 is fixed to the grid beam 5, and the strengthening segment 922 is connected to the flap 26 of the first fixing segment 21. The strengthening segment 922 is provided with an avoidance hole 9221, and the avoidance hole 9221 is communicated with the strengthening cavity 27. In the embodiment of the present application, the fixed beam segment 921 of the second connecting bracket may be provided with an inner groove, and the inner groove is provided on the side of the fixed beam segment 921 away from the strengthening segment 922. Setting an inner groove at the fixed beam segment 921 connected to the grid beam 5 can enhance the stiffness of the fixed beam segment 921. In addition, by opening the avoidance hole 9221 in the strengthening segment 922, in addition to reducing the weight of the second connecting bracket, it is also convenient to enter the strengthening cavity 27 of the first fixing segment 21 from the avoidance hole 9221, increasing the number of weld beads between the first fixing segment 21 and the first connecting bracket 91, and further increasing the connection stability.
