[0033] Figure 1 This is a schematic diagram of a canopy mounting reinforcement beam assembly according to an embodiment of the present invention; Figure 2 for Figure 1 The diagram shows the connection relationship between the front crossbeam, the front roof, and the side beams of the canopy installation reinforcement beam assembly. Figure 3 for Figure 1 A schematic diagram of the rear crossbeam of the canopy installation reinforcement beam assembly shown. Figure 4 for Figure 1 The cross-sectional view of section AA of the canopy installation reinforcement beam assembly shown. Figure 5 for Figure 1 A schematic diagram of the side beams of the canopy installation reinforcement beam assembly shown; Figure 6 for Figure 1 A schematic diagram showing the connection relationship between the front crossbeam and the side beams of the canopy installation reinforcement beam assembly; Figure 7 for Figure 1 A schematic diagram of the rear crossbeam of the canopy installation reinforcement beam assembly shown. Figure 8 for Figure 1 The diagram shows the application of silicone sealant to the rear crossbeam of the canopy installation reinforcement beam assembly.
[0034] like Figures 1-8 As shown, the canopy installation reinforcement beam assembly includes a front crossbeam 1 and a rear crossbeam 2 arranged opposite each other, two side beams 3 arranged opposite each other, a front top cover 4, and a rear top cover 5.
[0035] A frame is formed by connecting the front crossbeam 1, one side beam 3, the rear crossbeam 2, and the other side beam 3 end to end. The frame includes a first surface and a second surface arranged opposite to each other. The front top cover 4 covers the first surface of the front crossbeam 1, is fixedly connected to the front crossbeam 1, and is fixedly connected to the ends of the two side beams 3 facing the front crossbeam 1. A first cavity is formed between the front top cover 4 and the front crossbeam 1. The rear top cover 5 covers the first surface of the rear crossbeam 2, is fixedly connected to the rear crossbeam 2, and is fixedly connected to the ends of the two side beams 3 facing the rear crossbeam 2. A second cavity 6 is formed between the rear top cover 5 and the rear crossbeam 2. The first surfaces of the front top cover 4, the rear top cover 5, and the two side beams 3 are used to connect with the skylight glass 7.
[0036] The first surface is the surface facing outwards, and the second surface is the surface facing inwards. Based on the roof dimensions of different vehicle models, the maximum permissible size of the panoramic sunroof 7 is calculated to provide stable support. The panoramic sunroof 7 is designed within this size range. Simultaneously, the required dimensions of the front roof cover 4 and rear roof cover 5 are calculated so that the panoramic sunroof 7 can obtain stable support after being connected to the front roof cover 4 and rear roof cover 5. At the same time, the front roof cover 4 can connect to the front end of the vehicle frame, and the rear roof cover 5 can connect to the rear end of the vehicle frame. The front roof cover 4, panoramic sunroof 7, and rear roof cover 5 can cover the entire roof. During assembly, the first ends of the two side beams 3 on the same side are welded to the opposite ends of the front crossbeam 1, and the second ends of the two side beams 3 on the same side are welded to the opposite ends of the rear crossbeam 2. The four components together form a frame. The front roof 4 is connected to the front crossbeam 1 and the two side beams 3 at their adjacent ends. Due to the structural characteristics of the front crossbeam 1, a first cavity is formed between them. Similarly, the rear roof 5 is connected to the rear crossbeam 2 and the two side beams 3 at their adjacent ends. Due to the structural characteristics of the rear crossbeam 2, a second cavity 6 is formed between them. The cavities enhance the connection strength between the front roof 4 and the front crossbeam 1, and between the rear roof 5 and the rear crossbeam 2, thereby further improving the stable support for the panoramic glass 7 and maximizing its size. Then, the panoramic glass 7 is connected to the front roof 4, the rear roof 5, and the two side beams 3. The front roof 4 is then fixedly connected to the front end of the vehicle frame, and the rear roof 5 is fixedly connected to the rear end of the vehicle frame. The two sides of the frame and the two sides of the front roof 4 and the rear roof 5 are then connected to the side panels of the vehicle, completing the connection between the panoramic glass mounting reinforcement beam assembly, the panoramic glass 7, and the vehicle body.
[0037] The panoramic sunroof mounting reinforcement beam assembly of this invention, with the cooperation of the frame, front roof 4, rear roof 5 and panoramic glass 7 to cover the roof, can match the roof size of different vehicle models by adjusting the size of the front roof 4 and rear roof 5 and the distance between them, without increasing the overall size of the panoramic glass 7 by splicing glass, thus ensuring the integrity of the panoramic glass 7.
[0038] Figure 1 and Figure 2 All views are from inside the vehicle looking outwards. To avoid mutual obstruction, Figure 1 The front crossbeam 1 is not shown in the image. Figure 1 As shown, in this embodiment, the lower ends of the two side beams 3 are respectively welded to the left and right ends of the rear crossbeam 2, and the upper ends of the two side beams 3 are respectively welded to... Figure 2The front crossbeam 1 is welded at both ends, and the two side beams 3 are nearly perpendicular to the front crossbeam 1 and the rear crossbeam 2. The front roof 4 covers the front crossbeam 1 on the outside of the vehicle and is fixedly connected to the four sides of the front crossbeam 1, forming a first cavity in the middle. The rear roof 5 covers the rear crossbeam 2 on the outside of the vehicle and is fixedly connected to the four sides of the rear crossbeam 2, forming a second cavity 6 in the middle. To facilitate the welding connection of the side beams 3 to the front crossbeam 1 and the rear crossbeam 2, welding edges 9 are fixed at opposite ends of the side beams 3 in the extension direction. To facilitate the welding connection with the side panels of the vehicle body, welding edges 9 are fixed on both sides of the front roof 4 and the rear roof 5 where they connect to the side panels of the vehicle body, as well as on the opposite sides of the two side beams 3. The first surfaces of the two side beams 3, i.e., the surfaces facing outwards, are provided with silicone sealant and are directly connected to the sunroof glass 7 via silicone sealant. Depending on the width of the sunroof glass, the distance between the two side beams 3 can be reduced or increased. Depending on the length of the sunroof glass, the distance between the front crossbeam 1 and the rear crossbeam 2 in the X-direction, i.e., along the length of the vehicle body, can be reduced or increased. The Z-direction height of the first and second cavities 6 can be 20-70mm, which enhances rigidity and significantly improves NVH performance. The rear roof 5 is a thin-walled component and must withstand snow pressure. Since it is located in the middle of the rear roof 5, its modality is lower, and care must be taken to avoid acoustic chambers and idling excitation. Therefore, the recommended Z-direction height of the second cavity 6 in the middle area of the rear roof 5 is 20-50mm. The specific dimensions of the front crossbeam 1, rear crossbeam 2, side beams 3, front roof 4, and rear roof 5 can be adjusted to match the roof dimensions of different vehicle models and the specific requirements of the sunroof glass.
[0039] Optionally, a first characteristic rib 21 is provided on the rear crossbeam 2. The first characteristic rib 21 protrudes towards the second surface and extends along the extension direction of the rear crossbeam 2, with its opposite ends extending to the end of the rear crossbeam 2 facing the side beam 3. This arrangement strengthens the structural rigidity of the rear crossbeam 2 and further enhances the rigidity of the entire canopy installation reinforcement beam assembly.
[0040] Figure 3 For example, the perspective from outside the vehicle to inside the vehicle. Figure 1 and Figure 3 As shown, in this embodiment, the first feature rib 21 protrudes towards the second surface, i.e., towards the inward direction, near the side beam 3 of the rear crossbeam 2. Figure 3 The upper surface of the first feature rib 21 forms a groove that extends in the same direction as the rear crossbeam 2, with an extension length slightly shorter than that of the rear crossbeam 2. It bends towards the side beam 3 near both ends of the rear crossbeam 2 and extends to the end of the rear crossbeam 2 facing the side beam 3. Depending on the actual application, the specific arrangement of the first feature rib 21 on the rear crossbeam 2, the height of its protrusion towards the vehicle interior, and its extension length can all be adjusted appropriately.
[0041] Optionally, a second characteristic rib 22 is provided on the rear crossbeam 2. The second characteristic rib 22 is adjacent to the side of the first characteristic rib 21 away from the side beam 3 and protrudes towards the rear top cover 5. A plurality of first adhesive grooves 23 are spaced apart on the second characteristic rib 22, and the second characteristic rib 22 is adhesively connected to the rear top cover 5. The provision of the second characteristic rib 22 further improves the overall rigidity of the rear crossbeam 2.
[0042] like Figure 3 As shown, in this embodiment, the second feature rib 22 protrudes towards the rear top cover 5, that is, protrudes outwards from the vehicle, extending along the extension direction of the rear crossbeam 2, approximately the same length as the rear crossbeam 2, and is adjacent to the recessed first feature rib 21, forming a Z-direction height difference. The greater the height difference, the more beneficial it is to the rigidity of the rear crossbeam 2. Since the rear needs to accommodate the roller shutter mechanism and motor, higher rigidity is crucial, but it must also meet the requirements for headroom inside the vehicle and avoid creating a feeling of oppression. Therefore, the height difference between the second feature rib 22 and the first feature rib 21 is preferably 10-50mm. Two rows of first adhesive grooves 23 are provided on the second feature rib 22, respectively arranged on both sides along the extension direction of the second feature rib 22, and the two rows of first adhesive grooves 23 are staggered. After injecting adhesive into the first adhesive grooves 23 and adhesively bonding the second feature rib 22 to the rear top cover 5, it can better resist the torsional deformation of the rear top cover 5. The number of first adhesive grooves 23 is set to an odd number, and 5-11 can be set according to the size of the rear top cover 5. Depending on the actual application, the specific arrangement position of the second feature rib 22 on the rear crossbeam 2, the height of its protrusion towards the outside of the vehicle, and its extension length can all be adjusted appropriately.
[0043] Optionally, the rear crossbeam 2 has a first protrusion 24 at the end away from the side beam 3 and a second protrusion 25 at the end facing the side beam 3. Both the first protrusion 24 and the second protrusion 25 protrude towards the rear top cover 5. The first protrusion 24 has a plurality of mounting holes 26 spaced apart, and a second glue groove 27 is provided between adjacent mounting holes 26. The second protrusion 25 is welded to the rear top cover 5.
[0044] like Figure 3 , Figure 4As shown, in this embodiment, the first protrusion 24 and the second protrusion 25 both protrude towards the rear top cover 5, that is, towards the outside of the vehicle. The first protrusion 24 is provided with four mounting holes 26 spaced apart. In order to improve the local rigidity of the mounting hole 26, a protruding structure is provided on the first protrusion 24, and the mounting hole 26 is opened through the protruding structure. The protruding structure must ensure that it can meet the rigidity target of at least 150 N / mm for the stamping process and the local mounting point. At least one second glue groove 27 is provided between adjacent mounting holes 26. When connecting the rear crossbeam 2 and the rear roof 5, the rear crossbeam 2 is welded to the rear roof 5 on opposite sides along the width direction of the vehicle body. To facilitate welding, welding edges 9 can be provided on both sides of the rear crossbeam 2. The welding edges 9 are welded to the rear roof 5. Glue is injected into the second glue groove 27 on the first protrusion 24 and the first glue groove 23 on the second feature rib 22. The first protrusion 24 and the second feature rib 22 are glued to the rear roof 5 respectively. Bolts are passed through the mounting holes 26 on the first protrusion 24 and the corresponding positions on the rear roof 5 to achieve bolt connection between the rear crossbeam 2 and the rear roof 5. At the same time, the second protrusion 25 is welded to the corresponding position on the rear roof 5. Therefore, the fixed connection between the rear crossbeam 2 and the rear roof 5 adopts multiple connection methods such as bolt connection, glue connection and welding connection, which ensures the connection strength between the two, increases the torsional resistance, and greatly improves the NVH and durability of the whole vehicle. Moreover, as Figure 4 As shown, the first protrusion 24, the second feature rib 22 and the second protrusion 25 are spaced apart, and the adjacent two are recessed in the direction away from the rear top cover 5, forming a second cavity 6 between them and the rear top cover 5. Figure 4 The left end of the middle rear roof 5, away from the side beam 3, bends towards the inward direction and then extends horizontally for a certain distance, for matching and welding connection with the rear end of the vehicle body frame. Depending on the actual application, the specific location and number of mounting holes 26 on the first protrusion 24, the specific location and number of the second adhesive groove 27, and the protrusion height of the first protrusion 24 and the second protrusion 25 can all be appropriately adjusted.
[0045] Optionally, multiple first transverse ribs 28 are provided at intervals on the rear crossbeam 2, and the first transverse ribs 28 protrude towards the rear top cover 5. The first transverse ribs 28 are provided to further increase the rigidity of the rear crossbeam 2.
[0046] like Figure 3 As shown, in this embodiment, the rear crossbeam 2 has three first transverse ribs 28 spaced apart between the first protrusion 24 and the second characteristic rib 22. Additionally, four fixing holes 29 are provided between the first protrusion 24 and the second characteristic rib 22 for installing a sunshade. The specific arrangement and number of the first transverse ribs 28 on the rear crossbeam 2 can be adjusted appropriately according to the actual application.
[0047] Optionally, each of the two side beams 3 is provided with a third feature rib 31. The third feature rib 31 protrudes towards the second surface, extends along the extension direction of the side beam 3, and connects with the first feature rib 21. The third feature rib 31 is provided to improve the rigidity of the side beam 3 itself. After the side beam 3 is welded to the rear cross beam 2, the third feature rib 31 connects with the first feature rib 21 to form a semi-circular recessed feature rib facing inward, which helps to strengthen the structural rigidity of the entire frame.
[0048] like Figure 1 As shown, in this embodiment, the two side beams 3 are arranged in a mirror symmetrical manner, and the third feature rib 31 is arranged on the opposite side of the two side beams 3. The third feature rib 31 extends along the extension direction of the side beam 3 and extends to the ends of the opposite ends of the side beam 3. After the side beam 3 is welded to the rear cross beam 2, the lower ends of the two third feature ribs 31 are respectively connected to the left and right ends of the first feature rib 21.
[0049] Optionally, a plurality of connecting holes 32 are spaced apart on the side beam 3, and a boss 33 is provided near the connecting holes 32, the boss 33 protruding toward the first surface.
[0050] like Figure 5 As shown, in this embodiment, multiple connecting holes 32 are spaced apart on the third feature rib 31 for installing sunshades. To improve the rigidity of the locations of the connecting holes 32, multiple protruding structures are provided within the groove formed by the third feature rib 31. Connecting holes 32 are drilled through these protruding structures, and a height difference is formed between the protruding structures and the third feature rib 31. The protruding structures must also meet the rigidity target of at least 150 N / mm for the stamping process and local mounting points, which can greatly reduce the risk of matching problems and abnormal noises during assembly. Some connecting holes 32 are located in areas of low deflection; to improve the rigidity of these locations, bosses 33 are also provided near the connecting holes 32, such as... Figure 5 As shown, the connecting hole 32 in the middle is located at the point of weakest deflection. Therefore, three bosses 33 are provided near the connecting hole 32 in the middle to increase the rigidity of the connecting hole 32. Depending on the actual application, the specific location and number of connecting holes 32 on the side beam 3, as well as the location and number of bosses 33, can be adjusted appropriately.
[0051] Optionally, a protrusion 34 is provided on the side beam 3, which protrudes towards the first surface for connection with the skylight glass 7, and a reinforcing rib 35 is provided on the protrusion 34.
[0052] A protrusion 34 is provided to offer a surface for the adhesive 8, allowing the side beam 3 to be directly connected to the skylight glass 7 via the adhesive 8. The width of the protrusion 34 on the side beam 3 can be increased or decreased depending on the width of the skylight glass 7. Adding reinforcing ribs 35 further enhances the rigidity of the side beam 3, thus providing stable support for the skylight glass 7. Figure 1 and Figure 5 As shown, each of the two side beams 3 has a protrusion 34 on one side that is opposite to each other. The protrusion 34 protrudes outward from the vehicle and extends in the same direction as the side beams 3, extending to both ends of the side beams 3. An arc-shaped reinforcing rib 35 is provided on both protrusions 34.
[0053] Optionally, a second transverse rib 41 is provided on the front top cover 4, protruding towards the front crossbeam 1; a third transverse rib 51 is provided on the rear top cover 5, protruding towards the rear crossbeam 2. The second transverse rib 41 and the third transverse rib 51 are provided to improve the overall rigidity of the front top cover 4 and the rear top cover 5, respectively, and must meet the requirements of the safety top cover compression resistance and the front crossbeam mode of the top cover in NVH.
[0054] like Figure 6 and Figure 7 As shown, in this embodiment, second horizontal ribs 41 are arranged at intervals along the extending direction of the front top cover 4, and third horizontal ribs 51 are arranged on the side of the rear top cover 5 facing the side beam 3. The third horizontal ribs 51 extend in the same direction as the rear top cover 5 and are slightly shorter than the extending length of the rear top cover 5. The front top cover 4 and the rear top cover 5 also provide adhesive surfaces for bonding with the skylight glass 7, such as... Figure 8 As shown, on the rear top cover 5, on opposite sides along the extending direction of the third transverse rib 51, silicone sealant 8 is applied respectively. Similarly, Figure 6 On the front top cover 4, on opposite sides along the extension direction of the second horizontal rib 41, glass glue 8 is also applied. To increase the connection rigidity between the skylight glass 7 and the front top cover 4 and the rear top cover 5, the glued surface is guaranteed to have at least two rows, and the glued surface width is ≥70mm. Figure 7 In the middle, the central part of the rear roof 5 is the styling surface 52, which forms a complete external styling surface feature with the panoramic glass 7, and protrudes outwards to increase the surface rigidity of the rear roof 5.
[0055] Figure 9 For Figure 1 The diagram shows the installation of the canopy reinforcement beam assembly and the canopy glass. Figure 9As shown, to achieve a stable connection with the sunroof mounting reinforcement beam assembly, the circumferential surface of the sunroof glass 7 is coated with silicone sealant 8. Furthermore, at the corresponding positions of the front roof 4 and rear roof 5, an additional strip of silicone sealant 8 is applied along the width of the vehicle body to enhance the connection rigidity between the sunroof glass 7 and the front and rear roof 4 and 5, thus ensuring the overall NVH and safety performance of the vehicle. The sunroof glass 7 is a shaped glass with a relatively thick thickness, typically 4.56mm-4.76mm thick laminated glass. To meet NVH sound insulation requirements and ensure the safety of the roof's pressure resistance, its thickness cannot be too thin.
[0056] The present invention also provides a vehicle including the canopy mounting reinforcement beam assembly described in any of the above embodiments.
[0057] The vehicle using this invention covers the roof with the help of the frame, front roof 4, rear roof 5 and panoramic glass 7. The roof size of different models can be matched by adjusting the size of the front roof 4 and the rear roof 5 and the distance between them. There is no need to increase the overall size of the panoramic glass by splicing glass, thus ensuring the integrity of the panoramic glass.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
