Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a roof structure and a vehicle. Background Art

[0002] The roof structure of some vehicles is equipped with both a canopy and a metal roof cover. The canopy is usually connected to the overlapping edge of the side outer panel by glass glue, and the metal roof cover is usually connected to the side outer panel by welding. This type of roof structure usually faces the following technical problems:

[0003] In order to ensure the strength and rigidity of the metal roof, a downwardly folded reinforcing flange is provided on the edge of the metal roof, and the width of the reinforcing flange is relatively large. The relatively wide reinforcing flange limits the distance between the top surface of the metal roof and the overlapping edge of the side outer panel, resulting in the distance between the top surface of the metal roof and the overlapping edge of the side outer panel being generally larger than the distance between the top surface of the canopy and the overlapping edge of the side outer panel, which in turn results in a surface difference between the top surface of the metal roof and the top surface of the canopy, which has an adverse effect on the wind resistance of the vehicle.

[0004] The skylight is connected to the overlapping edges of the side outer panels with glass glue. The installation accuracy of the skylight is difficult to ensure, and there is also a problem of abnormal noise between the skylight and the metal roof cover. Utility Model Content

[0023] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] like Figures 1 to 4 A roof structure shown includes a side outer panel 1, a metal roof cover 2 and a skylight 3. The side outer panel 1 is provided with a first flange 104 extending inwardly. The metal roof cover 2 includes a roof cover body 201, a second flange 202 extending obliquely from the outer edge of the roof cover body 201 toward the outer side and downwardly, and a third flange 203 extending obliquely from the lower edge of the second flange 202 toward the inner side and downwardly. The third flange 203 is welded to the side outer panel 1. The skylight 3 is glued to the first flange 104. The top surface of the skylight 3 is flush with the top surface of the roof cover body 201.

[0026] By adopting the above technical solution, by setting the second flange 202 and the third flange 203 at the outer side of the metal roof 2, the second flange 202 and the third flange 203 form a V-shaped flange structure, and the strength and rigidity of the V-shaped flange structure are greater than the strength and rigidity of the conventional flange. Under the condition of ensuring the strength and rigidity of the metal roof 2, the size of the V-shaped flange structure in the vertical direction can be made smaller than the size of the conventional flange in the vertical direction, and then it is easier to eliminate the surface difference between the metal roof 2 and the canopy 3, so that the top surface of the canopy 3 is flush with the top surface of the roof body 201, which helps to reduce the wind resistance of the vehicle.

[0027] In some embodiments, the corner between the second flange 202 and the top cover body 201 is rounded, and the corner between the third flange 203 and the second flange 202 is rounded. In the above technical solution, setting the corner to be rounded has the characteristic of being easy to implement.

[0028] In some embodiments, the side outer panel 1 further includes an outer panel body 101, a fourth flange 102 extending downward from the top edge of the outer panel body 101, and a fifth flange 103 extending downward from the lower edge of the fourth flange 102, a first flange 104 extending inward from the lower edge of the fifth flange 103, and a third flange 203 welded to the fifth flange 103. With the above technical solution, the fourth flange 102 is provided to improve the structural strength of the top of the side outer panel 1, thereby making the size of the top of the side outer panel 1 smaller in the vertical direction, reducing the height difference a between the top of the side outer panel 1 and the metal top cover 2, and helping to reduce the wind resistance of the vehicle.

[0029] In specific implementation, the third flange 203 can be connected to the fifth flange 103 by laser welding. During the welding process of the metal top cover 2, a fixture can be used to prevent the metal top cover 2 from deforming. Making the top of the side outer panel 1 smaller in the vertical direction can reduce the restrictions on the fixture, which helps to reduce the welding difficulty of the metal top cover 2. Using a fixture to prevent the metal top cover 2 from deforming can ensure the welding accuracy of the metal top cover 2 even when the strength and rigidity of the V-shaped flange structure are small, which helps to further reduce the size of the V-shaped flange structure in the vertical direction.

[0030] In some embodiments, the width n of the fourth flange 102 in the vertical direction is 1 mm-2 mm. Controlling the width of the fourth flange 102 in the vertical direction to 1 mm-2 mm can meet the structural strength requirements of the top of the side outer panel 1 and also make the size of the top of the side outer panel 1 in the vertical direction smaller. As a preferred solution, the width of the fourth flange 102 in the vertical direction is 1 mm.

[0031] In some embodiments, the angle between the fifth flange 103 and the first flange 104 is 127°-135°. A suitable angle between the fifth flange 103 and the first flange 104 can ensure the structural strength while taking into account the convenience of welding the metal top cover 2.

[0032] In some embodiments, the distance between the top surface of the top cover body 201 and the first flange 104 is 4mm-4.5mm. By optimizing the roof structure, the distance between the top surface of the top cover body 201 and the first flange 104 can be controlled to be 4mm-4.5mm while ensuring that the distance m between the lower edge of the third flange 203 and the first flange 104 is ≥ 3mm. The distance between the top surface of the top cover body 201 and the first flange 104 is smaller, which can more easily eliminate the surface difference between the metal top cover 2 and the awning 3. As a specific example, the distance between the top surface of the top cover body 201 and the first flange 104 and the distance between the top surface of the awning 3 and the first flange 104 are both h, 4mm≤h≤4.5mm.

[0033] In some embodiments, the roof structure further includes a stopper 5 supported on the upper side of the first flange 104, and the canopy 3 is supported on the upper side of the stopper 5. With the above technical solution, the stopper 5 can reduce or even eliminate the abnormal noise problem of the canopy 3, and the stopper 5 supports the canopy 3, which helps to ensure the installation accuracy of the canopy 3. In specific implementation, the canopy 3 is usually a glass canopy.

[0034] In some embodiments, the canopy 3 is connected to the first flange 104 by glass glue 4 .

[0035] In some embodiments, a sealing strip 6 is connected to the outer edge of the skylight 3 , and a sealing lip of the sealing strip 6 abuts against the fifth flange 103 , so that the sealing strip 6 seals the gap between the skylight 3 and the side outer panel 1 .

[0036] In some embodiments, the inner side of the side enclosure outer panel 1 is also connected to a side enclosure inner panel 7 and a side enclosure reinforcement panel 8 , and the side enclosure inner panel 7 and the side enclosure reinforcement panel 8 can strengthen the support for the skylight 3 and the metal roof cover 2 .

[0037] The utility model also provides a vehicle, comprising any one of the above-mentioned roof structures.
