Background
Currently, in the field of manufacturing electric sightseeing vehicles, a common frame member (also called a member main body or a frame main beam) is shown in fig. 1 and 2, and includes two parts, i.e., a front end member a and a rear end member B, which are separated from each other. The front end girder A is a straight pipe, the middle part of the rear end girder B is in an arc-shaped bent form, and the other parts are in a straight pipe form. Although the frame girder with the shape and the structure is widely used, the frame girder also has some technical defects which are mainly shown in the following five aspects:
1. under the prior art, the process precision of the girder main body elbow is not high, and the parameters of materials, hardness and the like of raw materials in different batches are different, so that the resilience of the raw materials in the girder elbow processing process is unstable.
2. The girder main body pipe bending process is low in efficiency and high in labor cost. Specifically, because the length and the weight of the front end girder are large, the whole machining process needs manual carrying operation and coordination, at least two operators are needed to cooperate in the pipe bending process, and the labor intensity is high.
3. In the elbow part of girder main part, can't realize that different atress regions possess different intensity distributions.
4. The main bent pipe of the crossbeam has low universality, and different crossbeams are required to be matched with different vehicle types.
5. The girder main part does not run through to the rear of a vehicle from the locomotive, and the frame strength is insufficient.

The purpose of the present invention is to overcome the technical defects of the above four aspects of the prior art, and the purpose is achieved by the following technical solutions:
a novel process frame girder of a sightseeing vehicle comprises a first straight pipe, a first arc sheet metal part, a second straight pipe, a second arc sheet metal part and a third straight pipe which are fixedly connected in sequence from front to back.
On the basis of the technical scheme, the invention can adopt the following technical means so as to better or more specifically realize the purpose of the invention:
the parts of the first straight pipe, the first bent arc sheet metal part, the second straight pipe, the second bent arc sheet metal part and the third straight pipe, which are contacted with each other, are fixedly connected in a welding mode.
Further, the length of the first straight pipe is 440mm, the length of the second straight pipe is 2233mm, and the length of the third straight pipe is 882 mm.

3. Because the processing process is carried out in a segmented mode, the length of the workpiece is small, the weight is light, and therefore one worker can operate in the processing process, and the labor cost of the vehicle enterprises is remarkably saved.
4. The frame girder is formed by combining several sections of straight pipes with different specifications and bent-arc sheet metal parts, and the structural design can ensure that different stress areas of the frame girder have reasonable strength distribution.

Detailed Description
In order to facilitate a more complete understanding of the technical solutions of the present invention for those skilled in the art, an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 3 and fig. 4, a novel process frame girder 1 of a sightseeing vehicle comprises, from front to back, a first straight pipe 101, a first curved sheet metal part 102, a second straight pipe 103, a second curved sheet metal part 104 and a third straight pipe 105; the parts of the first straight pipe 101, the first bent arc sheet metal part, the second straight pipe, the second bent arc sheet metal part and the third straight pipe which are contacted with each other are fixedly connected in a welding mode.
In the embodiment, the length of the first straight pipe 101 is 440mm, the length of the second straight pipe 103 is 2233mm, and the length of the third straight pipe 105 is 882 mm. In addition, the first straight pipe 101, the second straight pipe 103 and the third straight pipe 105 are square pipes (the cross section is rectangular), wherein the width, the height and the thickness of the pipe wall of the first straight pipe 101 are respectively 80mm, 40mm and 3mm, the width, the height and the thickness of the pipe wall of the second straight pipe 103 are respectively 100mm, 50mm and 3mm, and the width, the height and the thickness of the pipe wall of the third straight pipe 105 are respectively 80mm, 40mm and 3 mm.
As shown in fig. 5, the first curved sheet metal part 102 is composed of an arc-shaped curved pipe portion and two connecting ends. The total horizontal length that first curved sheet metal component 102 corresponds is 600mm, and wherein the horizontal length that curved elbow portion corresponds is 450mm, and the length of two link ends is 70mm and 80mm respectively, and the total height of curved elbow portion is 227mm (namely the distance between the plane that the bottom of two link ends is located from the top surface highest point of curved elbow portion is 227mm), and the distance between the lower surface of curved elbow portion's upper surface and this part is 98 mm. It is emphasized that the first and second curved sheet metal parts 102, 104 are substantially identical in terms of shape, configuration and dimensions, differing only in that: firstly, the installation positions are different, the former is used for connecting the first straight pipe 101 and the second straight pipe 103, and the latter is used for connecting the second straight pipe 103 and the third straight pipe 105; secondly, since the first straight pipe 101 and the third straight pipe 105 have different widths and heights, the data of the cross-sectional dimension of each connecting end of the first curved sheet metal part 102 and the second curved sheet metal part 104 are different because they correspond to the first straight pipe 101 and the second straight pipe 103, respectively. In addition, as for the processing method, the first bent-arc sheet metal part and the second bent-arc sheet metal part (which can be collectively referred to as bent-arc sheet metal parts) are both formed by stamping through a metal stamping die, a single stamped part is in a cover shape, and the two combined parts are welded into a pipe shape in a welding mode, so that the processing mode is beneficial to improving the production efficiency of the bent-arc sheet metal parts and can ensure that the bent-arc sheet metal parts have enough strength.
In addition, in the process of implementing the present invention, the contact portions of the first straight pipe 101, the first curved sheet metal part 102, the second straight pipe 103, the second curved sheet metal part 104, and the third straight pipe 105 may be fixed by riveting, but welding is better in terms of technical effect. Particularly, the arc stamping process is adopted, so that the welding area of the stamping plate and the straight pipe can be increased, and the welding strength is increased. In addition, because the sheet metal process and the welding process are mature processes, and the frame girder 1 is formed by combining three sections of straight pipes and two sections of bent-arc sheet metal parts in a welding mode, as for each section of workpiece (the straight pipe or the bent-arc sheet metal part), the length and the weight of the workpiece are far smaller than those of a rear end girder B in the prior art, so that the assembly of the frame girder 1 can be realized by only one operator, compared with the prior art, the invention not only improves the precision of the bent part of the frame girder, can ensure that different stress areas of the frame girder have reasonable strength distribution, but also greatly improves the production efficiency, and obviously reduces the labor cost of vehicle manufacturing enterprises. In addition, in the overall structure of the frame, the structural design that the frame girder penetrates from the head to the tail of the frame can better ensure the overall strength performance of the frame and the integrity of the frame structure.
