Novel top cover structure of passenger car
By designing the first top beam and the top skeleton edge beam with a width greater than the top beam, the top beam and the side skin of the middle section of the passenger car roof cover structure are not in conflict with the air. The tensioning skin and welding resistance process are adopted to solve the problem of the passenger car roof cover. The problems of low production efficiency and uneven appearance achieve efficient production without additional equipment.

AI Technical Summary
The conventional top cover of the passenger bus is inefficient in production, and the outer guard surface is prone to protrude by the top beam, which leads to the need to increase high-precision equipment to ensure the accuracy of size and arc, and thicken putty during coating to make up for the smoothness and flatness of the appearance surface.
A new top cover structure for passenger cars is designed, where the width of the first top beam and the top skeleton edge beam is greater than the width of the top beam, so that the top beam in the middle section is suspended without any resistance to the side skin, and direct tensioning skin and welding resistance are used. Process to ensure smooth appearance without the need for additional high-precision equipment.
Through this structural design, the flatness of the appearance surface is solved, while avoiding the need to increase high-precision equipment and improving the production efficiency of the top cover.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bus manufacturing, and in particular relates to a new top cover structure of a bus. Background Art
[0002] At present, the production efficiency of conventional bus roofs is low, and the entire outer protective surface is easily protruded by the top cross beam. Therefore, it is necessary to add high-precision equipment to ensure the accuracy and error of the outer width and top curvature of each top cross beam. It is also necessary to thicken the putty during painting to compensate for the smoothness and flatness of the appearance. Utility Model Content
[0003] The purpose of the utility model is to provide a new roof structure of a passenger car to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of roof cover structure for a passenger car, including a roof cover, a first top cross beam is provided on the leftmost side of the roof cover, a top frame side beam is provided on the rightmost side of the roof cover, a plurality of top cross beams are provided between the first top cross beam and the top frame side beam, top side longitudinal beams are provided on the front and rear sides of the roof cover, a plurality of top longitudinal beams are provided between the top side longitudinal beams on the front and rear sides, side skins are provided on the first top cross beam and the top frame side beam, and the width of the first top cross beam and the top frame side beam is greater than the width of the top cross beam.
[0005] Preferably, the rear side of the first top cross beam is aligned with the rear side of the tail top cross beam.
[0006] The technical effects and advantages of the utility model are as follows: since the width of the first top crossbeam and the top frame side beam is greater than the width of the top crossbeam, the top crossbeam in the middle section is suspended in the air without conflict with the side skin, thus solving the problem of the flatness of the appearance surface without adding additional high-precision equipment.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] The utility model provides Figure 1-6 A new type of roof structure for a passenger car is shown, including a roof, wherein a first top cross beam 1 is provided on the leftmost side of the roof, a top frame side beam 3 is provided on the rightmost side of the roof, a plurality of top cross beams 2 are provided between the first top cross beam 1 and the top frame side beam 3, top side longitudinal beams 4 are provided on the front and rear sides of the roof, a plurality of top longitudinal beams 6 are provided between the top side longitudinal beams 4 on the front and rear sides, side coverings 5 are provided on the first top cross beam 1 and the top frame side beam 3, and the width of the first top cross beam 1 and the top frame side beam 3 is greater than the width of the top cross beam 2.
[0016] Specifically, the rear side of the first top cross beam 1 is aligned with the rear side of the tail top cross beam 4 .
[0017] Working principle:
[0018] During production, it is only necessary to directly tension the skin 5 between the first top cross beam 1 and the top frame side beam 3 with a process frame to resist welding, alternately resist welding the top side longitudinal beams 4 and the top longitudinal beams 6, and fully weld the side skins 5 after they are firmly welded. Since the width of the first top cross beam 1 and the top frame side beam 3 is greater than the width of the top cross beam 2, the top cross beam 2 in the middle section is suspended in the air with the side skins 5 without conflict, thus solving the problem of the flatness of the appearance surface without adding additional high-precision equipment.
[0019] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
