Detailed Description
In order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to perform clear and complete description of the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In one embodiment of the present invention, a roof structure of an automobile is disclosed, which includes a top cover 1 and a base 2, as shown in fig. 1.
Specifically, as shown in fig. 8, the base 2 includes a first side 2-1 and a second side 2-2 that are arranged at an acute angle, the first side 2-1 is fixedly connected to the side of the roof 1, the second side 2-2 is parallel and fixedly connected to the upper side of the side beam 3 in the automobile, a sealing member 4 is disposed between the second side 2-2 and the upper side of the side beam 3, and the outer side of the side beam 3 is fixedly connected to the body side plate 5 of the automobile. The side beam 3 and the vehicle body side plate 5 are fixedly connected in a welding mode or an integrated forming mode. In addition, the sealing element 4 is made of sealant, so that the sealing property between the base 2 and the edge beam 3 is better.
In summary, in the roof structure of the embodiment, the sealing member is arranged between the base and the side beam in the automobile, so that dust particles and liquid in the external environment can be prevented from entering the inside of the top cover, and the roof structure has better sealing performance when being assembled with the automobile body; in addition, the first side edge and the second side edge of the base are arranged at acute angles, the second side edge is correspondingly parallel to and fixedly connected with the upper side edge of the side beam, the connecting surface of the base and the side beam is an inclined surface inclined towards the outer side of the top cover, namely the connecting surface is an inclined surface inclined towards the outer side of the automobile body, when liquid splashes into the connecting part of the base and the side beam, the liquid can slide out along the inclined surface due to the action of gravity, the liquid can be effectively prevented from entering the connecting part of the base and the side beam, and further the contact and corrosion of a sealing element are prevented, so that the sealing performance of the roof structure when the roof structure is assembled with the automobile body is further enhanced, the roof structure is simple, and the manufacturing cost is low.
In the present embodiment, as shown in fig. 8, the upper edge of the body side panel 5 is fixedly connected to the middle of the outer side edge of the side sill 3, the first side edge 2-1 is fixedly connected to the inner side surface of the side edge of the roof panel 1, and the lower edge of the roof panel 1 extends to the outside of the outer side edge of the side sill 3 and is disposed at a gap from the upper edge of the body side panel 5. When dust particles in the external environment enter into the gap between the top cover 1 and the side plate 5 of the automobile body, the outer side edge of the boundary beam 3 blocks the gap, so that the dust particles cannot enter into the gap between the base 2 and the boundary beam 3, when liquid in the external environment splashes on the top cover 1, the liquid can drip along the lower edge of the top cover 1 due to the action of gravity, the liquid also cannot enter into the joint of the base 2 and the boundary beam 3, and the dustproof and waterproof effects of the roof structure and the assembled automobile body are better.
Furthermore, the lower edge of the top cover 1 is of a round angle structure, and the upper edge of the side plate 5 of the car body is of an arc-shaped structure at the joint with the edge beam 3, so that lines of the car roof structure are more concise and smooth, and the appearance is more attractive. Meanwhile, the paint surface can be more firmly attached to the top cover 1 and the vehicle body side plate 5 when the paint is sprayed.
In the present embodiment, as shown in fig. 1 to fig. 3 and fig. 6, the front side surface of the top cover 1 is an inclined structure that inclines downward, which is more in line with a streamlined low wind resistance design, and further can reduce the wind resistance coefficient of the top cover 1. And through the structure, the automobile does not need to be provided with an additional wind resistance cover, and the manufacturing cost of the automobile is further reduced.
In addition, as shown in fig. 1, 2 and 4, the front side surface of the roof panel 1 is provided with first hole grooves 8, and the first hole grooves 8 are arranged in pairs, respectively arranged at the left and right sides of the front side surface of the roof panel 1, and used for installing the outline marker lamps in front of the automobile; the rear side surface of the top cover 1 is provided with second hole grooves 9, and the second hole grooves 9 are also arranged in pairs and are respectively arranged on the left side and the right side of the rear side surface of the top cover 1 and used for installing the outline marker lamps behind the automobile.
And, be equipped with the strengthening rib and/or strengthen the boss on the medial surface of top cap, can strengthen the structural strength of top cap like this, and need not to set up extra reinforcement, and then make the wholeness of top cap better. In addition, the top cover structure can be reinforced by a design with different thicknesses according to the related performance requirements such as top pressure collision, for example, as shown in fig. 7, the thickness of the side plate of the top cover 1 is thicker than that of the upper plate; moreover, the connection parts of the top cover 1 and the side edge plates and the upper edge plate are connected through an arc-shaped structure, and the connection parts are thickened, so that the structural strength of the top cover 1 is improved.
In the embodiment, as shown in fig. 8, the top cover 1 and the base 2 are fixedly connected by screws, and the structural adhesive 6 is filled between the top cover 1 and the base 2, so that the connection between the top cover 1 and the base is firmer.
Further, as shown in fig. 1 and 5, the roof structure further includes a bracket 7, and the bracket 7 is fixed on the inner side surface of the roof panel 1, for providing a mounting structure for other systems in the vehicle interior, and supporting and fixing a decorative structure in the vehicle interior, for example, for fixing an interior lamp, etc.
Furthermore, the top cover and the base are made of SMC (Sheet molding compound) materials, the top cover made of the SMC materials is lighter than a traditional Sheet metal top cover, and meanwhile, the top cover has the advantages of being lower in production cost such as mold clamping detection and the like, capable of achieving light weight, reducing development cost, shortening development period and the like. In addition, the heat conductivity of the SMC material is much lower than that of a metal plate, and the design cost of heat insulation parts can be reduced by adopting the SMC material to prepare the top cover at the same ambient temperature.
In other embodiments, the top cover and the base are of an integral structure, namely, the top cover and the base are integrally formed, so that the integrity of the roof structure is better, and the processing flow of the roof structure is reduced.
In view of the above, it is only the specific embodiments of the present invention that other modifications and variations can be made by those skilled in the art based on the above-described embodiments in light of the above teachings. It should be understood by those skilled in the art that the foregoing detailed description is for the purpose of better explaining the present invention, and the scope of the present invention should be determined by the scope of the claims.
