Abstract

The utility model discloses a convex car roof technology, comprising a plurality of longitudinal beams, a plurality of beams, a top cover broad and an internal decorative board; the utility model is characterized in that the beam of the car roof is designed to a convex structure with salient middle and two gentle wings and the longitudinal beams on both sides of the beam are connected with the edges of the beams with convex structure to form an overall convex roof frame. The utility model has the advantages of reasonable design and convenient installation, and not only reduces the height of the car body, reduces the wind resistance, and saves oil, but also improves safety and stability of the traveling vehicles greatly. The car roof is applied to installation and modification of various cars.

Description

Convex passenger vehicle roof

The utility model relates to the topside technical field of power actuated vehicle, specifically a kind of highway passenger vehicle roof of convex structure.

Develop rapidly along with the highway passenger vehicle manufacturing technology, the dramatic growth of express highway mileage, and the passenger is to the requirement of the highway passenger vehicle speed of a motor vehicle, the passenger vehicle that travels on highway at present, its speed of a motor vehicle is obviously accelerated, and average speed per hour is per hour generally all about 80～100 kilometers.Yet existing various highway passenger vehicle, what major part adopted is the fixed type roof of high car body planar structure.Because the car body of this passenger vehicle is than higher, be subjected to the influence of windage also bigger, Vehicle Speed is fast more, the resistance of wind-engaging is big more, move on the body gravity in addition, so this passenger vehicle is not only safety and poor stability in the process of moving, and increased the consumption of fuel of vehicle greatly because of the factor of windage.So the development tendency that this high car body plane passenger vehicle roof and bus driving speed are constantly accelerated is far from suitable.

The purpose of this utility model is exactly to provide a kind of can reduce height of the carbody, increase vehicle safety and convex passenger vehicle roof stable, that save fuel oil at the deficiencies in the prior art.

The purpose of this utility model is achieved in that

This convex passenger vehicle roof, comprise that longeron, crossbeam, top cover cover plate and trim panel, mainly be crossbeam to be made as the mild convex structure of intermediate projections, both wings and the longeron of both sides is connected with the crossbeam end limit of each convex structure, form single-piece convex roof skeleton, on roof, also be provided with air regulator.

The utility model advantage compared with prior art mainly is reasonable in design.The mode of 2+2 or 2+3, the corridor that the middle passenger of being walks are generally adopted in the arrangement at seat in the highway passenger vehicle compartment now.The height in corridor is about 195 centimetres in the middle of the passenger car, and the seat height on both sides, compartment generally has only 100～110 centimetres, and the height that the passenger is sitting on the seat generally also has only 150～165 centimetres.So utilize the diff-H at compartment inside corridor and seat, the height of passenger car body can be lowered fully.Roof is made as nonplanar convex structure, so not only can influence the walking of passenger in the compartment, and can reduce the resistance of wind, reduce body gravity, improve the speed of a motor vehicle, reduce oil consumption by the height that reduces car body.Main is to have improved vehicle safety and stability under steam greatly.

Next is transformation and installs all more convenient.Adopt the roof of convex structure, do not change the length and the width of car body, do not change the chassis and the seat arrangement of vehicle.Just suitably reduce the height of car body, change the crossbeam and the skeleton of roof into the convex structure by original planar structure, connect and compose single-piece convex roof skeleton by longeron and crossbeam then.

Below in conjunction with drawings and Examples the utility model is described in detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model master TV structure scheme drawing;

Fig. 3 is the utility model plan structure scheme drawing.

As shown in drawings: this convex passenger vehicle roof, comprise that longeron 5, crossbeam 2, top cover cover plate 1 and trim panel 3, said crossbeam 2 is made as intermediate projections, the mild convex structure of both wings, and the crossbeam 2 end limits of the longeron 5 of both sides and each convex structure are connected and composed single-piece convex roof skeleton 4, top cover is installed on skeleton 4 is covered plate 1, installation trim panel 3 below skeleton 4 is provided with air regulator 6 on roof.In the middle of the compartment corridor and roof between height be 195 centimetres, the height between seat, both sides, compartment and the roof is 165 centimetres.

Claims

1, a kind of convex passenger vehicle roof, comprise that longeron (5), crossbeam (2), top cover cover plate (1) and trim panel (3), is characterized in that: said crossbeam (2) is made as the mild convex structure of intermediate projections, both wings and holds the limit to connect to form single-piece convex roof skeleton (4) with the crossbeam (2) of each convex structure the longeron (5) of both sides.

2, convex passenger vehicle roof according to claim 1 is characterized in that: be provided with air regulator (6) on roof.
