Description

Technical Field

[0001] The utility model relates to a panoramic sunroof, and particularly to a reinforcing structure for an economical panoramic sunroof. Background Art

[0002] With the continuous development of automotive technology, sunroofs, especially panoramic sunroofs, are increasingly favored by people. Compared with the panoramic glass roof panel installed from above the vehicle body, the economical panoramic glass roof panel installed from below the vehicle body can achieve a significant cost savings.

[0003] The existing economical panoramic sunroof adopts a ring-shaped reinforced vehicle body structure. The ring-shaped reinforced vehicle body structure adopts a single-layer structure, that is, a single-layer plate-shaped reinforcing structure formed by stamping metal sheets. This ring-shaped reinforced vehicle body structure can be connected to the vehicle body side beam to ensure the connection rigidity. However, these ring-shaped reinforced vehicle body structures have problems of cracks during the durability test stage due to poor welding quality.

[0004] Compared with ordinary sunroofs, due to the enlarged size of the economical panoramic sunroof, the size of the reinforcement of the vehicle body sunroof also becomes larger. Vehicles using the ordinary economical panoramic sunroof adopt a single-piece structure of the sunroof opening vehicle body, which is difficult to ensure durability and NVH (noise, vibration, and harshness) performance.

[0005] Regarding the NVH problem, although it can be improved by adding a mass block behind the ring-shaped reinforced vehicle body structure, since the existing reinforced vehicle body structure adopts a single-layer plate-shaped reinforcing structure, there is no way to add a mass block to the ring-shaped reinforced vehicle body structure.

[0006] Therefore, the existing ring-shaped reinforced vehicle body structure for the economical panoramic sunroof has problems of welding strength and stress concentration, and also needs to solve the problem that the NVH cannot be overcome by increasing the mass block.

[0007] The information disclosed in the background part of the present utility model is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those of ordinary skill in the art.

[0019] Preferably, the box-shaped structure is formed by bending a steel plate, and the two ends of the steel plate are welded at the lower surface of the box-shaped structure.

[0020] Preferably, the box-shaped reinforcement frame further includes sides located between the front part and the rear part and fixedly connected to the arms of the front part and the rear part; the cross-sections of the front part, the rear part, the connecting member and the sides are all closed box-shaped structures; the box-shaped reinforcement frame further includes a first connecting member and a second connecting member, the main body of the first connecting member is connected to the lower surface of the side, and the side plate of the first connecting member is connected to the body side structure; the main body of the second connecting member is connected to the lower surface of the rear part, and the side plate of the second connecting member is connected to the body side structure; the vehicle body roof is provided with a second opening corresponding to the first opening of the box-shaped reinforcement frame, and a connecting part with a U-shaped bend is arranged at the second opening, and the connecting part surrounds the edge of the first opening of the box-shaped reinforcement frame; the rear part is provided with a mass block mounting hole, and the mass block is mounted in the box-shaped structure in the rear part through the mass block mounting hole; the box-shaped structure includes an upper surface, a lower surface and a recessed part recessed from the lower surface; the connecting part includes a side surface and a bottom surface; wherein, the bottom surface of the connecting part is connected to the recessed part of the lower surface of the box-shaped structure.

[0021] Compared with the prior art, the technical effects of the box-shaped reinforcement frame for the economy panoramic sunroof of the present invention are as follows:

[0022] 1. Improve the overall stiffness of the sunroof roof opening part.

[0023] The existing annular reinforced body structure adopts a single-piece structure, and the stiffness of the structure is weak. The box-shaped reinforcement frame of the present invention adopts a closed box-shaped structure, which improves the rigidity of the reinforcement frame.

[0024] 2. Improve the commerciality and durability of the sunroof roof.

[0025] The box-shaped reinforcement frame for the economy panoramic sunroof of the present invention changes the welding position with the sunroof roof, so that even if problems such as poor welding quality occur, the defects can be hidden inside without affecting the assembly of the sunroof roof seal. Moreover, the improvement of the welding position can also prevent durability cracks caused by stress concentration.

[0026] 3. Improve NVH performance.

[0027] Vehicles using economy sunroofs are prone to NVH problems at the rear end of the sunroof roof. For the single-piece reinforcement structure of the existing sunroof roof, there is not enough space to increase the mass block to solve the NVH problem. The box-shaped reinforcement frame of the present invention adopts a box-shaped structure, so there is sufficient space to increase the mass block, thereby being able to solve the NVH problem of the sunroof roof.

[0069] It should be understood that the drawings are not necessarily drawn to scale and present simplified representations of various features for the purpose of illustrating the principles of the present utility model. The specific design features disclosed in the present utility model (including, for example, specific dimensions, directions, positions, and shapes) will be determined in part by the specific environment in which it is to be applied and used.

[0070] In these drawings, throughout the several views of the drawings, the same reference numerals denote the same or equivalent parts of the present utility model. Detailed implementation manners

[0071] Hereinafter, various embodiments of the present utility model will be referred to in detail. Examples of these embodiments are shown in the drawings and described as follows. Although the present utility model will be described in conjunction with the exemplary embodiments, it should be understood that this specification is not intended to limit the present utility model to these exemplary embodiments. On the contrary, the present utility model is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms, and other embodiments that may be included within the spirit of the present utility model and the scope defined by the appended claims.

[0072] In the present application, the so-called "inside" refers to the direction towards the center of the box-shaped reinforcing frame; the so-called "outside" refers to the direction away from the center of the box-shaped reinforcing frame.

[0073] The box-shaped reinforcing frame for an economical panoramic sunroof according to an embodiment of the present invention is installed below the vehicle body roof to support the vehicle body roof. The box-shaped reinforcing frame undertakes the reinforcement function of the economical panoramic sunroof on the vehicle body and is connected to the vehicle side structure to ensure the overall rigidity of the panoramic sunroof. To connect the vehicle body roof and the box-shaped reinforcing frame, the inner edge of the vehicle body roof adopts an inwardly curved structure, and the two are connected together by welding.

[0074] The following refers to the attached Figures 1 - 8 to illustrate the box-shaped reinforcing frame for an economical panoramic sunroof according to an embodiment of the present invention.

[0075] The box-shaped reinforcing frame 100 for an economical panoramic sunroof according to an embodiment of the present invention is installed below the vehicle body roof 200 and is connected to the vehicle body roof 200. The box-shaped reinforcing frame 100 is a hollow frame and a hollow first opening 180 is formed inside, which is used to correspond to the second opening 210 of the vehicle body roof 200. The box-shaped reinforcing frame 100 is installed below the vehicle body roof 200, see Figure 1 .

[0076] See Figure 1 and Figure 6 , at the second opening 210 of the vehicle body roof 200, a connecting portion bent inward is provided, and through the connecting portion, the vehicle body roof 200 can be connected to the box-shaped reinforcing frame 100 at the first opening 180. The connecting portion of the vehicle body roof 200 includes a side surface 220 and a bottom surface 230. The side surface 220 extends downward from the upper surface of the vehicle body roof 200, and the bottom surface 230 extends outward from the side surface 220, thereby forming an inward-opening U-shaped connecting portion to wrap the opening edge of the box-shaped reinforcing frame 100 and weld it.

[0077] See Figure 2 , the box-shaped reinforcing frame 100 includes a front portion 110, a rear portion 130, two side portions 120, a first connecting member 140, and a second connecting member 150. The above-mentioned parts are welded by CO 2 to form a ring-shaped hollow frame of the box-shaped reinforcing frame 100.

[0078] Among them, the front portion 110, the rear portion 130, and the two side portions 120 form a hollow frame, and the first connecting member 140 and the second connecting member 150 are used to connect the hollow frame to the vehicle body side structure (not shown).

[0079] The front portion 110 is located in the front part of the entire box-shaped reinforcing frame 100 (i.e., in the direction close to the vehicle head). The front portion 110 is a substantially U-shaped component, including a main body and arms extending from both sides of the main body. The cross-section of the front portion 110 is a closed box-shaped structure. See Figure 3b andFigure 3c The front part 110 is formed by bending a steel plate, with an overlapping part formed at its lower part, and the overall structure is formed by spot welding at this overlapping part.

[0080] The front part 110 is provided with various holes or slots at different positions, such as tool processing holes, welding through holes, etc. Figure 3a is a top view of the front part 110. In order to arrange the sealant 110d for connecting with the body roof, a depression is provided on the upper surface of the front part 110, and welding holes 110c are provided on the upper surface, so that the welding tool can enter through the welding holes 110c to weld the welding part 110e.

[0081] Specifically, referring to Figure 3b and Figure 3c The front part 110 includes an upper surface 110a and a lower surface 110b. Welding holes 110c and grooves for accommodating the sealant 110d are formed on the upper surface 110a. Welding parts 110e are formed by overlapping the two ends on the lower surface 110b. Welding holes 110c are formed on the upper surface 110a corresponding to the welding parts 110e, and a recessed part 110f is formed inside the lower surface 110b, and this recessed part 110f is used to connect with the bottom surface 230 of the body roof 200.

[0082] The rear part 130 is located at the rear part of the entire box-shaped reinforcement frame 100 (i.e., in the direction close to the rear of the vehicle). The rear part 130 is a substantially U-shaped component, including a main body and arms extending from both sides of the main body. Referring to Figure 5a and Figure 5b The cross-section of the rear part 130 is a closed box-shaped structure. The rear part 130 is formed by bending a steel plate, with an overlapping part formed at its lower part, and the overall structure is formed by spot welding at this overlapping part.

[0083] The rear part 130 is provided with various holes or slots at different positions, such as tool processing holes, welding through holes, mass block mounting holes, etc. Figure 5b is a top view of the rear part 130. In order to arrange the sealant 130d for connecting with the body roof, a depression is provided on the upper surface of the rear part 130, and welding holes 130c are provided on the upper surface. Figure 5a is a bottom view of the rear part 130, which shows the mass block mounting hole 130g, and the mass block 130h can be installed through this mass block mounting hole 130g.

[0084] Specifically, referring to Figure 5c and Figure 5d, the rear part 130 includes an upper surface 130a and a lower surface 130b. A welding hole 130c is formed at the upper surface 130a, and a groove for accommodating sealant 130d is provided. At the lower surface 130b, two ends overlap to form a welding part 130e, and a recessed part 130f is formed inside the lower surface 130b, and this recessed part 130f is used to connect with the bottom surface 230 of the vehicle body top cover 200. See Figure 5a and Figure 5d , a mass mounting hole 130g is opened at the lower surface 130b of the rear part 130, and a mass 130h can be mounted through this mass mounting hole 130g. When it is necessary to mount the mass 130h, the mass 130h is mounted into the space inside the rear part 130 through the mass mounting hole 130g, and then the mass 130h is fixed in the rear part using bolt T. See Figure 5e . And in order to fix the mass, weight reduction holes and holes for fixing bolt T are provided in the box-shaped structure. The box-shaped reinforcing frame of the present utility model has sufficient space to increase the mass.

[0085] Two side parts 120 are located between the front part 110 and the rear part 130 and connect the front part 110 and the rear part 130 together. The side part 120 is an elongated component. See Figure 4a . The cross-section of the side part 120 is a closed box-shaped structure. The side part 120 is formed by bending a steel plate, an overlapping part is formed at its lower part, and the overall structure is formed by spot welding at this overlapping part.

[0086] See Figure 4a and Figure 4b , the side part 120 includes an upper surface 120a and a lower surface 120b. A welding hole 120c is formed at the upper surface 120a; at the lower surface 120b, two ends overlap to form a welding part 120d, and a recessed part 120e is formed inside the lower surface 120b, and this recessed part 120e is used to connect with the bottom surface 230 of the vehicle body top cover 200.

[0087] See Figure 2 , the first connecting piece 140 is a plate-shaped component, and it is used to connect the side part 120 to the vehicle body side structure. The first connecting piece 140 includes a main body 140a and side plates 140b; when in use, the main body 140a of the first connecting piece 140 is welded to the lower surface 120b of one of the two side parts 120, and the side plates 140b of the first connecting piece 140 are welded to the vehicle body side structure.

[0088] See Figure 2, the second connecting member 150 is a plate-like member for connecting the rear portion 130 to the body side structure. The second connecting member 150 includes a main body 150a and a side plate 150b; in use, the main body 150a of the second connecting member 150 is welded to the lower surface 130b of the rear portion 130, and the side plate 150b of the second connecting member 150 is welded to the body side structure.

[0089] Although in the above embodiments of the present utility model, the cross-sections of the front portion, the rear portion, and the connecting member are all closed box-shaped structures, it is also possible to set the cross-section of a part thereof to a closed box-shaped structure as needed, while the cross-sections of other parts are not set to closed box-shaped structures. For example, only the cross-section of the rear portion is set to a closed box-shaped structure.

[0090] In the above embodiments of the present utility model, the mass block mounting block and the mass block are arranged in the box-shaped structure of the rear portion, but they can also be arranged in the box-shaped structure of any one of the front portion, the rear portion, and the connecting member.

[0091] For large vehicles, since the economic panoramic sunroof is relatively large in size, four components (front portion, rear portion, and two side portions) can be used to form an annular box-shaped reinforcement frame. For small vehicles using an economic panoramic sunroof, in order to reduce costs, the number of components can be reduced. As an option, the box-shaped reinforcement frame for the economic panoramic sunroof can also not be provided with the first connecting member 140, but instead, the arms on both sides of the front portion 110 and the rear portion 130 are extended and connected to each other, thereby omitting the first connecting member 140.

[0092] The various components of the present utility model are connected to each other by welding, and problems such as poor welding usually occur. To prevent this from happening, the welded connection can be changed to a bolt installation connection method. That is, the box-shaped reinforcement frames for the economic panoramic sunroof can also not be connected by welding, but by bolt connection. Refer to Figure 8 , holes are provided at the bottom of the components, and nuts are provided inside the holes, so that the various components can be connected by screws.

[0093] The box-shaped reinforcement frame of the present utility model for the economic panoramic sunroof adopts a closed box-shaped structure, which improves the overall structural strength of the opening part of the sunroof top cover.

[0094] The box-shaped reinforcement frame of the present utility model improves the connection method with the sunroof top cover. Compared with the existing reinforcement structure of the vehicle body sunroof, the structure of the present utility model improves the welding position between the sunroof reinforcement structure and the vehicle body top cover. The connection part of the existing vehicle body sunroof extends downward from the upper surface and is joined and welded to the side surface of the opening part of the reinforcement structure (refer to Figure 9)。The vehicle roof used in conjunction with the box-shaped reinforcement frame for the economy panoramic sunroof of the present utility model adopts an inwardly bent U-shaped structure. The bottom surface 230 of the connecting portion engages with the recessed portion (e.g., the recessed portion 130f of the rear portion 130) of the box-shaped reinforcement frame member and is connected together by welding. By improving the position of the welding points at the opening of the vehicle roof, the occurrence of poor welding quality exposure and stress concentration problems is prevented. And since the welding position is inside the box-shaped reinforcement frame, even if poor welding quality occurs, it can be hidden inside without affecting the appearance.

[0095] Moreover, in addition to the welded connection, the box-shaped reinforcement frame for the economy panoramic sunroof of the present utility model is also connected to the vehicle roof using sealant.

[0096] To cope with the annular cavity reinforcement structure of the sunroof of the present utility model, the sealing strip is changed from being installed on the connecting portion of the sunroof roof in the prior art to being installed on the sunroof system (see Figure 6 and Figure 9 ).

[0097] Vehicles using economy sunroofs are prone to NVH problems at the rear end of the sunroof roof. For the single-piece reinforcement structure of the existing sunroof roof, there is not enough space to add a mass block to solve the NVH problem. Since the box-shaped reinforcement frame of the present utility model adopts a box-shaped structure, there is sufficient space to add a mass block, thereby being able to solve the NVH problem of the sunroof roof.

[0098] The foregoing description of the specific exemplary embodiments of the present utility model has been presented for purposes of illustration and description. The foregoing description is not intended to be exhaustive nor to limit the present utility model to the precise form disclosed, and obviously many changes and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the present utility model and its practical application so that others skilled in the art may realize and utilize the various exemplary embodiments of the present utility model and its various alternative forms and modifications. The scope of the present utility model is defined by the appended claims and their equivalents.
