Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive body design technology, specifically a novel roof awning overlap structure. Background Technology
[0002] The overlapping structure of a panoramic sunroof is a crucial technology in both automotive manufacturing and architectural design. In automotive manufacturing, the design of the overlapping structure of the sunroof, as an important part of the vehicle body, directly affects the overall appearance, safety, and manufacturing costs. For example, the overlapping portion of a panoramic sunroof requires precise stamping processes and side forming die design to ensure a perfect integration of the sunroof with other parts of the vehicle body, while simultaneously meeting safety and aesthetic requirements.
[0003] The existing roof awning overlap structure has certain shortcomings. In the current structure, the roof reinforcement plate is not connected to the rear crossbeam assembly. The roof reinforcement plate is welded to the outer roof panel at the front, and then glued together at the back. The rear crossbeam assembly is glued to the top of the outer roof panel and then welded together at the rear. Currently, the roof awning structure involves first welding the outer roof panel and the roof reinforcement plate into an assembly, and then welding it to the body-in-white assembly. This prevents the roof reinforcement plate from being welded to the rear crossbeam assembly. Furthermore, because the roof reinforcement plate and the outer roof panel are welded together as an assembly, the overall length is too long, making it prone to deformation during transportation or welding, which is detrimental to controlling welding precision. The lack of welding between the rear crossbeam assembly and the roof reinforcement plate reduces the top area's resistance to dents, lowers the vehicle's torsional rigidity, and is detrimental to improving overall vehicle strength.
[0004] Therefore, a solution is needed. Utility Model Content

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.
[0022] Referring to Figs. 1-2 The utility model discloses an embodiment provides a technical scheme to realize: a novel awning roof cover lap joint structure, characterized by: including roof outer plate 1, roof rear crossbeam upper cover plate 2, roof rear crossbeam 3 and awning reinforcement plate 4.
[0023] The core is that the roof rear crossbeam upper cover plate 2 is arranged at the bottom of the roof outer plate 1, the roof rear crossbeam 3 is arranged at the bottom of the roof rear crossbeam upper cover plate 2, the awning reinforcement plate 4 is arranged at the bottom of the roof outer plate 1, the roof outer plate 1 is in Z type structure, the roof rear crossbeam upper cover plate 2 is in obtuse angle structure, the roof rear crossbeam 3 is in Z type structure, and the awning reinforcement plate 4 is in rectangular structure.
[0024] Specifically, the width of the bottom of the roof rear crossbeam upper cover plate 2 is greater than the width of the bottom of the roof rear crossbeam 3, the width of the bottom of the awning reinforcement plate 4 is greater than the width of the bottom of the roof rear crossbeam upper cover plate 2, and the width of the bottom of the roof outer plate 1 is greater than the width of the bottom of the awning reinforcement plate 4.
[0025] In detail, the roof rear crossbeam upper cover plate 2 and the roof rear crossbeam 3 are welded into a roof rear crossbeam assembly.
[0026] The left end of the awning reinforcement plate 4 and the right end of the roof rear crossbeam upper cover plate 2 are connected and welded.
[0027] The purpose of the scheme is to enhance the torsional performance and bending stiffness of the whole vehicle, the roof assembly is formed into a complete force transmission path and a closed loop by welding between the awning reinforcement plate 4 and the roof rear crossbeam assembly, so that the torsional performance and bending stiffness of the whole vehicle are enhanced.
[0028] The scheme changes the upper piece sequence of the roof outer plate 1, the awning reinforcement plate 4 is welded with the side wall assembly first and then welded with the roof rear crossbeam assembly after the awning reinforcement plate 4 is upper, so that a complete force transmission path and structure are formed at the top of the vehicle body, the roof outer plate 1 is upper after that, the appearance performance of the whole vehicle is ensured, the gluing between the roof rear crossbeam assembly and the roof outer plate 1 is reserved, the gluing between the awning reinforcement plate 4 and the roof outer plate 1 is reserved, and the overall performance is further enhanced. Under the premise of not affecting the appearance performance of the whole vehicle and changing the welding process, only the upper piece sequence is changed, the torsional performance and bending stiffness of the whole vehicle are enhanced, and the overall dent resistance of the roof is enhanced.
[0029] Working principle: the roof rear crossbeam upper cover plate 2 and the roof rear crossbeam 3 are welded into a roof rear crossbeam assembly, when welding, the awning reinforcement plate 4 is upper, is welded with the side wall assembly first, then is welded with the roof rear crossbeam assembly, and finally the roof outer plate 1 is upper to complete installation.
[0030] The utility model discloses 1 - top cover outer plate;2 - top cover rear crossbeam upper cover plate;3 - top cover rear crossbeam;4 - awning stiffener, these components are all general standard parts or the components of the person skilled in the art, and the structure and principle are all known to the person skilled in the art and can be known through the technical manual or through the conventional experimental method, the problem solved by the utility model is that the existing structure is not connected with the awning stiffener and the top cover rear crossbeam assembly, the front welding between the awning stiffener and the top cover outer plate, the rear adhesive connection, the top cover rear crossbeam assembly and the top cover outer plate top rely on the adhesive bonding, and the back is welded together. The awning plate top cover structure is that the top cover outer plate and the awning stiffener are first assembled and welded into an assembly, and then are welded with the body-in-white assembly, so that the awning stiffener and the top cover rear crossbeam assembly cannot be welded. Moreover, after the awning stiffener and the top cover outer plate are welded into an assembly, the overall length is too long, and deformation is prone to occur during transfer or welding, which is not conducive to the control of welding precision. Since the top cover rear crossbeam assembly and the awning stiffener are not welded, the top region resistance to denting is reduced, the vehicle torsion and stiffness are reduced, and the vehicle strength is not improved. The utility model greatly enhances the torsion performance and bending stiffness of the vehicle, enhances the resistance to denting of the top cover during the use of the vehicle, and improves the vehicle crash performance.
