Referring to fig. 1 and 2, a sectional type longitudinal beam 100 according to an embodiment of the present invention includes a front longitudinal beam 11, a rear longitudinal beam 21, and a middle longitudinal beam 31 connected between the front longitudinal beam 11 and the rear longitudinal beam 21. The rear longitudinal beam 21 and the middle longitudinal beam 31 are lower than the front longitudinal beam 11 relative to the vehicle body, and at least one axle mounting hole for the vehicle axle to pass through is formed in the rear longitudinal beam 21.

The sectional longitudinal beam 100 is composed of the front longitudinal beam 11, the rear longitudinal beam 21 and the middle longitudinal beam 31, and the length of each part is greatly reduced compared with the sectional longitudinal beam 100, so that the processing difficulty is reduced, and the manufacturing precision is easier to ensure. Similarly, the front longitudinal beam 11, the rear longitudinal beam 21 and the middle longitudinal beam 31 are assembled until the installation is needed, because the length is controlled, the transportation is more convenient. The rear side member 21 and the middle side member 31 are positioned lower than the front side member 11, and a bridge mounting hole is formed in the rear side member 21, through which an axle can be passed and fixed to the segment side member 100. In this manner, the axle does not need to be additionally connected to the segmented side rail 100 via brackets, which helps to reduce vehicle height.

The number of the axle mounting holes depends on the vehicle type to be adapted, for example, in the first embodiment, the vehicle type to which the sectional type longitudinal beam 100 is adapted is a 4X4 vehicle type, and only one axle exists at the rear-section longitudinal beam 21, so the axle mounting hole is a corresponding one. Similarly, in the second embodiment, the vehicle model to which the sectional type longitudinal beam 100 is adapted is a 6X6 vehicle model, and there are two axles at the rear longitudinal beam 21, so there are two corresponding axle mounting holes. It is understood that the number of axle mounting holes depends on the number of axles of the vehicle to be fitted at the rear longitudinal beam 21, that is, the sectional longitudinal beam 100 provides the axles at the rear longitudinal beam 21 with a corresponding number of axle mounting holes, so as to facilitate the axle installation, and is not limited specifically herein.

Specifically, the middle longitudinal beam 31 is a groove structure with one open side, and the opening faces away from the front longitudinal beam 11 and the rear longitudinal beam 21. The middle longitudinal beam 31 is in a straight groove shape with equal section. The groove-shaped structure can reduce the weight while ensuring the structural strength, and the opening back to the front longitudinal beam 11 and the rear longitudinal beam 21 is convenient for being connected in a more fitting manner. When the automobile is installed, the opening of the middle section longitudinal beam 31 faces the inner side of the automobile body, so that the requirement that a storage battery, an oil tank, an air storage cylinder and the like are installed on the outer side of the middle section longitudinal beam 31 is met. The constant-section straight-groove-shaped middle-section longitudinal beam 31 can enable the sectional type longitudinal beam 100 to be suitable for different vehicle types only by simply changing the length of the manufactured middle-section longitudinal beam 31 according to the wheel base, and is convenient for subsequent train type development.

More specifically, the front side member 11 and the rear side member 21 are both of a groove-shaped structure with one side opened, and the openings of the two side opened are opposite to the middle side member 31. When the vehicle is mounted, the opening of the rear side member 21 faces outward, so that the axle is connected to the inner side of the rear side member 21. Similarly, the groove-shaped structure can reduce the weight while ensuring the structural strength, and the opening faces away from the middle section longitudinal beam 31, so that the connection is more convenient.

Further, the sectional longitudinal beam 100 further includes a reinforcing beam, which is groove-shaped and has an opening opposite to the opening of the front longitudinal beam 11 and connected to the front longitudinal beam 11. The reinforcing beam is at least partially embedded in the front longitudinal beam 11, and forms a box-shaped section front longitudinal beam assembly 10 together with the front longitudinal beam 11. The front side member 11 is required to bear a complicated load, and the strength of the front side member 11 can be effectively enhanced by the reinforcing beam without increasing the weight excessively.

Still further, the segmented stringer 100 also includes a connector. The front longitudinal beam 11 and the rear longitudinal beam 21 are respectively lapped with two ends of the middle longitudinal beam 31, a plurality of corresponding connecting holes are formed in the lapping positions of the front longitudinal beam 11, the rear longitudinal beam 21 and the middle longitudinal beam 31, and the middle longitudinal beam 31 is connected with the front longitudinal beam 11 and the rear longitudinal beam 21 by penetrating through the connecting holes through connecting pieces. The front longitudinal beam 11 and the rear longitudinal beam 21 are respectively connected with the middle longitudinal beam 31 in an overlapping manner through connecting pieces, so that the front longitudinal beam and the rear longitudinal beam are convenient to disassemble and assemble. In this embodiment, the connecting member is a bolt 41, and one end of the bolt 41 passes through the connecting hole and is fixed by a nut. It is understood that in other embodiments, other types of connectors may be used, such as rivets, staples, etc., and are not specifically limited herein.

Referring to fig. 3 and 4, the present invention further provides a frame assembly 200, which includes the above-mentioned two sectional longitudinal beams 100 and a plurality of cross beams 51, wherein the two sectional longitudinal beams 100 are disposed oppositely in parallel and spaced, and the plurality of cross beams 51 are connected between the two sectional longitudinal beams 100. The two sectional longitudinal beams 100 are connected through the cross beam 51, and the requirements on the overall torsional strength and rigidity are met. The frame assembly 200 can also be matched with wheel bases of different vehicle types by replacing middle section longitudinal beams 31 with different lengths.

As previously mentioned, in one embodiment, the frame assembly 200 is adapted to the 4X4 vehicle type corresponding to the first embodiment described above, with each segmented side rail 100 having a bridge mounting hole (shown in FIG. 3). In another embodiment, frame assembly 200 is adapted to a 6X6 vehicle model corresponding to the second embodiment described above, with each segmented rail 100 having two axle mounting holes (shown in FIG. 3). It is understood that the number of the bridge mounting holes depends on the vehicle type to be adapted, and is not particularly limited thereto.

Further, the frame assembly 200 further comprises at least one axle 61, the axle 61 being mounted at the location of the axle mounting hole and at least partially located between the two sectional side rails 100 and connected to the sectional side rails 100, the axle of the axle 61 protruding from the axle mounting hole. The axle 61 is connected to the two sectional side rails 100 and partially located between the two sectional side rails 100, and plays a certain role similar to that of the cross beam 51, thereby improving the torsional strength and rigidity of the frame assembly 200.

Further, the front side member 11 and the rear side member 21 are respectively overlapped with both ends of the middle side member 31, and at least two cross members 51 are provided. Two ends of one cross beam 51 are respectively connected to the lap joint position of the front-section longitudinal beam 11 and the middle-section longitudinal beam 31 in the two sectional longitudinal beams 100, and two ends of the other cross beam 51 are respectively connected to the lap joint position of the rear-section longitudinal beam 21 and the middle-section longitudinal beam 31 in the two sectional longitudinal beams 100. The overlapping position where the two cross members 51 are connected to the two sectional stringers 100 contributes to the structural strength of the overlapping portion.

The utility model also provides a vehicle comprising the frame assembly 200. By carrying the frame assembly 200, the height of the vehicle is effectively reduced, the transportability is improved, mass air transportation and sea transportation are facilitated, the height limit is controlled better, or a larger loading space is obtained at the same height. In addition, the gravity center of the vehicle is lower, and the running is more stable and safe.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the utility model.
