[0035] 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.

[0036] The embodiment of the present application provides a vehicle side roof system, which can solve the technical problem of enhancing the rigidity of the side roof in the related art. 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, wherein the reinforcing bracket 2 includes an energy absorbing section 23 and a first fixed section 21 and a second fixed section 22 respectively connected to both ends of the energy absorbing section 23, wherein the first fixed section 21 and the second fixed section 22 are both installed on the inner side of the side roof body 1, and the energy absorbing section 23 is arranged at intervals in the side roof body 1, and the energy absorbing section 23 is provided with an energy absorbing hole 231; a bracket structure 3, wherein both ends of the bracket structure 3 are respectively fixed to the energy absorbing section 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 top cover body 1, so that the raised section 31 can support the side top cover body 1 and improve the rigidity under the normal state of the vehicle. The first fixing section 21 and the second fixing section 22 are fixed to the side top cover body 1, so that the energy absorbing section 23 can be spaced apart from the side top cover, and the spacing can refer to the spacing along the Y direction of the vehicle (that is, the lateral direction of the vehicle). The bracket structure 3 is fixed to the energy absorbing section 23, and the raised section 31 is opposite to the energy absorbing hole 231. When the side top cover is hit, the side top 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 in the 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 bracket 2 and reduce the possibility of the bracket breaking, thereby solving the technical problem in the related art that the side top 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 one 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 approximately along a direction perpendicular to the extension direction of 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 one 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 near the collapse section 311. The collapse section 311 can be directly connected to the first connection section 312 and the second connection section 313, or 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 on the opposite sides of the energy absorbing hole 231, and the first stabilizing section 32 and the second stabilizing section 33 can have a certain length to increase the contact surface between each of them and the energy absorbing section 23, and enhance the connection stability. 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 surrounded 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 along an extending direction perpendicular to the collapsing section 311, that is, the first connecting section 312 can be perpendicular to the collapsing section 311, and the first connecting section 312 can also have a small angle with the collapsing section 311, and the angle can be a negative angle. The specific angle can be adjusted and set according to the collapsing effect, as well as the adjustment of the molding process of the part. In addition, the second connecting section 313 extends obliquely from the connection with the second stabilizing section 33 toward the side close to the collapsing section 311, and the angle between the second connecting section 313 and the collapsing section 311 can be an acute angle or an obtuse angle, see 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 enables the support structure 3 to collapse and deform toward one side of the first connecting section 312 when the support structure 3 collapses as a whole, see Figure 5 As shown, the dotted line in the figure represents a schematic diagram of the structure of the support structure 3 after collapse, and the structure corresponding to the dotted 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, and 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, so that when the support structure 3 collapses as a whole, the extrusion normal can be 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, both sides of the first arc section 314 are provided with first collapse notches 3141, 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, both sides of the second arc section 315 are provided with second collapse notches 3151, 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 stabilizing section 32 and the first connecting section 312 are connected by the first arc section 314, and the first connecting section 312 and the collapsing section 311 are connected by the second arc section 315, so that the strength and stability of the connection can be improved, that is, the supporting performance of the support structure 3 on the side top cover body 1 can be improved, and when the support structure 3 is hit on the side top cover body 1 and the support 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 to move toward the side close to the energy absorption hole 231, the first connecting segment 312 is also gradually compressed and deformed. The first collapse notch 3141, the first collapse hole 3142, the second collapse notch 3151 and the second collapse hole 3152 are respectively arranged, which 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 collapse 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 provided with a first reinforcing rib 3121, which extends along a spacing direction perpendicular to the energy absorbing section 23 and the collapsing section 311; the second connecting section 313 is provided with a second reinforcing rib 3131, which extends along an arrangement direction of the second connecting section 313 and the collapsing section 311. That is, the first reinforcing rib 3121 may extend along an extension direction of the first connecting section 312, and the second reinforcing rib 3131 may also extend along an extension direction of the second connecting section 313. Preferably, the first reinforcing rib 3121 and the second reinforcing rib 3131 are respectively arranged at the middle of the first connecting section 312 and the second connecting section 313, and the middle may refer to a middle position perpendicular to an arrangement direction of the second connecting section 313 and the collapsing section 311, or may be other positions slightly offset from the middle position. By respectively providing 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 collapse 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 implementations, the collapsing section 311 is provided with a plurality of shock absorbing grooves 3111 at intervals along its extension direction, each of the shock absorbing grooves 3111 is filled with shockproof glue 4, and the shockproof glue 4 is sandwiched between the shock absorbing grooves 3111 and the side top cover body 1. The shock absorbing grooves 3111 can be formed by a part of the collapsing section 311 being recessed toward a side away from the side top cover body 1, and each of the shock absorbing grooves 3111 can be filled with shock absorbing glue, which is applied to the shock absorbing grooves 3111, and expands and connects to the inner wall of the side top cover body 1 after drying. At this time, the collapsing section 311 can have a certain gap with the side top cover body 1 under the support of the shock absorbing glue, and the shock absorbing glue has a certain support rigidity at this time, and can also absorb part of the energy when the side top cover hits. In the embodiment of the present application, the elasticity and viscosity of the shockproof glue 4 itself can reduce the impact force of the collision, play a certain buffering role, and protect the side top cover body 1 and some structures around the side top cover body 1 to reduce the possibility of damage.

[0044] In some optional embodiments, the vehicle side roof system may further include: a cross beam 5, the cross beam 5 is mounted on the side roof body 1, the first fixing section 21 is connected to the cross beam 5, and the first fixing section 21 is connected to the side roof body 1; a side enclosure inner upper cross beam 6, the side enclosure inner upper cross beam 6 is connected to the side enclosure B-pillar inner plate 7, the second fixing section 22 is connected to the side enclosure inner upper cross beam 6, and is fixed to the side enclosure B-pillar inner plate 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 may be manufactured separately and then welded and fixed. In the 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 the top surface of part 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, thereby enhancing 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 upper inner cross beam 6 of the side enclosure, so that the second fixed section 22 is fixed under the action of the upper inner cross beam 6 of the side enclosure. Since the inner panel 7 of the side enclosure B-pillar is fixed to the upper inner cross beam 6 of the side enclosure, the second fixed section 22 can be connected to the inner panel 7 of the side enclosure B-pillar to increase the connection point of the second fixed section 22 and enhance the connection stability of the second fixed section 22. In addition, part of the energy absorbing section 23 can also be connected to the inner panel 7 of the side enclosure B-pillar. Furthermore, part of the second fixed section 22 away from the upper inner cross beam 6 of the side enclosure 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 beam 5 and the second fixing section 22 to the side inner upper cross beam 6, the force received by the energy absorbing section 23 can be transmitted to the cross beam 5 and the side inner upper cross beam 6 through the first fixing section 21 and the second fixing section 22, respectively, so as to effectively disperse the force, reduce the force concentrated on the energy absorbing section 23, and reduce the possibility of damage to the energy absorbing section 23. And by dispersing the force received by the energy absorbing section 23 to the cross beam 5 and the side inner upper cross beam 6, the vehicle body materials can be used more reasonably to avoid waste and excessive use of materials.

[0045] In some optional embodiments, the vehicle side roof system further includes a side enclosure outer upper cross beam 8, the side enclosure outer upper cross beam 8 is connected to the side enclosure inner upper cross beam 6, and the side enclosure outer upper cross beam 8 and the second fixed section 22 are spaced apart along the Z direction of the vehicle. The side enclosure outer upper cross beam 8 may include a flange structure and a beam body connected to the flange, the flange of the side enclosure outer upper cross beam 8 may be connected to the side enclosure inner upper cross beam 6, and the beam body of the side enclosure outer upper cross beam 8 is spaced apart from the second fixed section 22 along the Z direction of the vehicle, and the interval may serve as an installation tolerance gap between the second fixed section 22 and the side enclosure outer upper cross beam 8, thereby reducing the possibility of mutual interference between the second fixed section 22 and the beam body of the side enclosure outer upper cross beam 8, and when some parts of the top of the vehicle collide, the second fixed section 22 may also have a certain movement buffer space.

[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 the first connecting bracket 91 is sandwiched between the side top cover 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. That is, the first fixing section 21 is fixed to the cross beam 5 at one end of the first fixing section 21 close to the cross beam 5 by the first connecting bracket 91 fixed to the cross beam 5 and 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 its connection. Since the thickness of the side top cover body 1 is relatively thin, the joint with the first fixing section 21 can be connected by bonding, which can not only ensure the tightness of the connection, but also effectively avoid the connection failure caused by insufficient material thickness.

[0047] See also Figure 7 and Figure 8As shown, in some alternative embodiments, the cross-sections of the first fixing section 21, the second fixing section 22 and the energy-absorbing section 23 are all in a "ji" shape. The first fixing section 21, the second fixing section 22 and the energy-absorbing section 23 each include a top panel 24 and side panels 25 fixed to opposite sides of the top panel 24. The side panels 25 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. 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 section 921 and a strengthening section 922 connected to the fixed beam section 921. The fixed beam section 921 is fixed to the grid beam 5, and the strengthening section 922 is connected to the flap 26 of the first fixing section 21. The strengthening section 922 is provided with an avoidance hole 9221, and the avoidance hole 9221 communicates with the strengthening cavity 27. In the embodiments of the present application, the fixed beam section 921 of the second connecting bracket may be provided with an inner groove, which is provided on the side of the fixed beam section 921 away from the strengthening section 922. Setting an inner groove at the fixed beam section 921 connected to the grid beam 5 can enhance the stiffness of the fixed beam section 921. In addition, by providing the avoidance hole 9221 in the strengthening section 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 section 21 from the avoidance hole 9221, increasing the number of weld beads between the first fixing section 21 and the first connecting bracket 91, and further increasing the connection stability.
