Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, specifically, it relates to a novel roof structure. Background Technology

[0002] In recent years, the automotive industry has flourished, and automotive roof technology has become increasingly mature. Currently, there are two main types of roofs: one is a fixed roof, which is the common form of car roof. It is a large covering with a large outline size and is part of the overall body structure. It has the advantages of high rigidity and high safety, and can protect occupants when the car rolls over. However, its disadvantage is that it is fixed and has no ventilation. Convertible roofs are usually used in high-end cars or sports cars. They move part or all of the roof through electric or mechanical transmission, allowing people to fully enjoy the sunshine and air and experience the fun of driving. However, its disadvantage is that the mechanism is complex and the safety and sealing are poor.

[0003] Patent No. 202120006989.2, published on December 7, 2021, discloses a sunroof roof assembly structure, belonging to the technical field of automotive design and manufacturing. This utility model's sunroof roof assembly structure includes a roof assembly for mounting the sunroof assembly, with both sides of the roof assembly welded and fixed to a B-pillar assembly. Its key feature is that a connecting beam is provided between the B-pillar assembly and the roof assembly, and the connecting beam is located below the sunroof horizontal plate of the sunroof assembly. The front and rear sides of the connecting beam are closed hollow structures, while the middle is a layered structure composed of two sheets of sheet metal. The left and right ends of the connecting beam are screwed and fixed to the upper side beam of the B-pillar assembly. This utility model's sunroof roof assembly structure optimizes the force transmission path of the ring structure, enhances strength during side impacts and rollovers, and can effectively improve the rigidity and fatigue resistance of the entire vehicle.

[0004] In the existing technology, since the sunroof mounting plate and the front roof beam are bonded together with mounting adhesive, abnormal noises from the sheet metal are easily caused during driving. In addition, the sunroof mounting plate has too many structural features, resulting in a large overall structural weight. Utility Model Content

[0005] The present invention aims to provide a novel top cover structure with simplified structure and high installation strength.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel roof structure, including a front top crossbeam and a sunroof mounting plate disposed on the front top crossbeam, wherein the side of the sunroof mounting plate is connected to the front top crossbeam by bolts, and the corner of the sunroof mounting plate is provided with an adhesive groove.

[0007] The sunroof mounting plate has a protruding plate on its side, which is connected to the front top crossbeam by bolts.

[0008] The convex plates are distributed along one side of the sunroof mounting plate near the front top crossbeam.

[0009] There is a 6mm gap between the sunroof mounting plate and the front top crossbeam.

[0010] The adhesive application grooves are located at the four corners of the sunroof mounting plate.

[0011] The shape of the adhesive application groove is consistent with the direction of the skylight's ribs.

[0012] The sunroof mounting plate has an end mounting plate that overlaps with the side panel.

[0013] The end mounting plate is in the shape of a concave triangle.

[0014] The rooftop mounting plate is provided with skylight mounting holes, and a boss is provided between adjacent skylight mounting holes, the boss having a height of 12mm.

[0015] The technical effects of this utility model are as follows: by increasing the connection structure between the sunroof mounting plate and the car roof, the rigidity of the car roof system is improved, the roof's compressive strength is increased, and product safety is enhanced; the connection method between the front roof beam and the sunroof mounting plate is changed, reducing the risk of abnormal noises during car driving and road testing; and the weight of the roof system is reduced, resulting in a lighter overall vehicle.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0023] Please see Figure 1-4 A novel roof structure includes a front roof crossbeam 1 and a sunroof mounting plate 2 mounted on the front roof crossbeam 1. The side of the sunroof mounting plate 2 is connected to the front roof crossbeam 1 by bolts, and the corner of the sunroof mounting plate 2 is provided with an adhesive groove 3. By increasing the connection structure between the sunroof mounting plate 2 and the car roof, the rigidity of the car roof system is improved, the roof's pressure resistance is increased, and the product safety is enhanced. Furthermore, by changing the connection method between the front roof crossbeam 1 and the sunroof mounting plate 2, the risk of abnormal noise during car driving and road testing is reduced.

[0024] The sunroof mounting plate 2 has a protruding plate 4 on its side, which is connected to the front top crossbeam 1 by bolts; this allows the sunroof mounting plate 2 to be separated from the front top crossbeam 1, reducing the risk of sheet metal noise when the car is in motion.

[0025] The convex plates 4 are distributed along the side of the sunroof mounting plate 2 near the front top crossbeam 1; the reliability of the connection can be ensured by setting the convex plates 4 for the three fixing bolts.

[0026] There is a 6mm gap between the sunroof mounting plate 2 and the front roof crossbeam 1; this reduces the risk of sheet metal noises when the car is in motion.

[0027] The adhesive grooves 3 are distributed at the four corners of the sunroof mounting plate 2; by adding installation adhesive between the sunroof mounting plate 2 and the outer panel of the roof, the stability of the connection is improved and the safety of the product is increased. The adhesive grooves 3 are 75mm long.

[0028] The shape of the adhesive groove 3 is consistent with the direction of the ribs of the skylight, which allows the skylight to be connected to the skylight mounting plate 2 more stably.

[0029] The sunroof mounting plate 2 has an end mounting plate 5 that overlaps with the side wall; the useless features at the rear of the sunroof mounting plate 2 are simplified to achieve weight reduction. With the boundary already determined, it only extends at the rear of the sunroof mounting plate 2 and is trimmed at the part that interferes with the surrounding parts. This can meet the strength requirements and reduce the weight of the sunroof mounting plate 2.

[0030] The end mounting plate 5 is a concave triangle; the triangular structure can improve the overall strength and reduce the risk of breakage.

[0031] The roof mounting plate is provided with skylight mounting holes 6, and a boss 7 is provided between adjacent skylight mounting holes 6. The boss 7 has a height of 12mm. The structure of the skylight mounting plate 2 and the skylight mounting holes 6 is optimized to improve the rigidity of the roof structure.

[0032] The technical effects of this utility model are as follows: by increasing the connection structure between the sunroof mounting plate 2 and the car roof, the rigidity of the car roof system is improved, the roof's compressive strength is increased, and product safety is enhanced; the connection method between the front roof beam 1 and the sunroof mounting plate 2 is changed, reducing the risk of abnormal noises during car driving and road testing; and the weight of the roof system is reduced, resulting in a lighter overall vehicle.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
