These and other aspects of embodiments of the utility model will be apparent from and elucidated with reference to the description and drawings described hereinafter. In the description and drawings, particular implementations of embodiments of the utility model are disclosed in detail as being indicative of some of the ways in which the principles of embodiments of the utility model may be employed, but it is understood that the scope of the embodiments of the utility model is not limited correspondingly. On the contrary, the embodiments of the utility model include all alternatives, modifications and equivalents as may be included within the spirit and scope of the appended claims.
In some embodiments, a schematic frame assembly is shown in fig. 1, 1 is a frame assembly, including a front cross member 101, a middle cross member 102, a rear cross member 103, a right side member 104, and a left side member 105. The left side member 105 is welded to the right side member 104 by the front cross member 101, the center cross member 102, and the rear cross member 103.
As shown in fig. 2 to 5, the powertrain 2 is installed between the center cross member 102, the rear cross member 103, the right side member 104, and the left side member 105, and the piping assembly 3 is disposed from the left or right side of the powertrain 2. Because of the small space available, a recess 1044 is provided on one outer surface of the frame beam in this embodiment, so that a sufficient line passing space is left for the pipeline assembly 3. The recess may be provided on the side facing the power train, or may be provided on the top side, bottom side, etc. of the frame rail as needed, as long as the battery pack installation space is not additionally occupied. For traditional pipeline arrangement in the scheme of girder, the pipeline of this scheme can be arranged in the outside of frame roof beam, can reduce the assembly degree of difficulty like this, and avoids the mode of punching on the roof beam can increase the intensity of frame roof beam, also avoids the edge of hole to possibly cut apart the pipeline and leads to the problem of potential safety hazard simultaneously. When the pipeline is arranged on the outer side of the frame beam, the maintenance can be performed without cutting the frame during the maintenance, and meanwhile, the maintainability of the chassis pipeline is improved.
In some embodiments, as shown in fig. 2-5, the outer surface of the frame rail facing the powertrain 3 is provided with a recess 1044. Because the power assembly mainly occupies the Y-direction space of the chassis, the cross section of the frame beam needs to be made as narrow as possible to leave space for the power assembly, and therefore, the length of the top surface and the bottom surface of the frame beam is shorter, the length of the left surface and the right surface is longer, and the concave part is arranged on the surface facing the power assembly in a better embodiment. By locating the fuel or brake line assembly in the ventral recess of the frame rail, space utilization is more reasonable. And meanwhile, the risk that the fuel oil or the brake pipeline assembly is arranged at other positions and is knocked is avoided.
In some embodiments, as shown in fig. 2 to 5, a reinforcing rib 1043 is disposed in the frame beam, and the reinforcing rib 1043 is disposed opposite to the recess 1044, so as to reasonably utilize the internal space of the cross section of the frame beam.
In some embodiments, as shown in fig. 2 to 5, the frame beam is surrounded by an outer plate 1041 and an inner plate 1042, the reinforcing rib 1043 is disposed on the outer plate 1041, and the inner plate 1042 forms the recess 1044. In order to strengthen the strength of the frame beam, the reinforcing ribs are required to be arranged in the frame beam, as the inner plates forming the frame beam are provided with the concave parts, the strength of the frame beam can be balanced by arranging the reinforcing ribs on the other surface corresponding to the surface where the concave parts are located, and the bending and torsion resistance of the frame beam is improved.
In some embodiments, as shown in fig. 2-5, the bottom of the frame rail is flush with the bottom of the powertrain 3. When the power assembly is completely installed, the bottom of the power assembly is flush with the bottom of the frame beam, so that the power assembly and the frame beam form a whole, and the Y-directional bending resistance and torsion resistance of the whole vehicle are effectively improved. Meanwhile, gaps between the power assembly and the left side beam and between the power assembly and the right side beam are small, Y-direction space of the whole vehicle is effectively utilized, capacity of the power assembly, namely a battery pack, is increased, and pure electric endurance mileage of the whole vehicle is improved.
In some embodiments, as shown in fig. 2 to 5, a groove 1045 is provided below the frame beam, and a mounting hole is provided on the groove 1045, and the mounting hole is configured to fixedly connect the frame beam with the powertrain 3 through a bolt 201. The frame beam can effectively improve the space utilization rate through the optimization of the section.
In some embodiments, as shown in fig. 2 to 5, the mounting holes penetrate through the frame beam in the vertical direction, so that the frame beam and the battery pack are more in line with mounting habit when mounted, the problem that the frame beam strength is affected due to the fact that bolts are easily loosened due to the action of gravity in a left mounting mode and a right mounting mode is avoided, and meanwhile the problem that holes are formed in the outer sides of the frame beam in the left mounting mode and the right mounting mode is avoided.
In some embodiments, as shown in fig. 2-5, the powertrain is a battery pack.
Still further embodiments of the present utility model, as shown in fig. 1-5, provide a chassis assembly including the frame rail described above that secures the pipe assembly 3 within the recess 1044 of the frame rail via the pipe clamp 301. Through the pipe clamp of setting up the outside at the depressed part, can prevent that the pipeline from falling out in the depressed part, guarantee pipeline assembly's stability and security.
Still further embodiments of the present utility model, as shown in fig. 1-5, provide a vehicle including the frame rail described above. For traditional pipeline arrangement in the scheme of girder, the pipeline of this scheme can be arranged in the outside of frame roof beam, can reduce the assembly degree of difficulty like this, and avoids the mode of punching on the roof beam can increase the intensity of frame roof beam, also avoids the edge of hole to possibly cut apart the pipeline and leads to the problem of potential safety hazard simultaneously. When the pipeline is arranged on the outer side of the frame beam, the maintenance can be performed without cutting the frame during the maintenance, and meanwhile, the maintainability of the chassis pipeline is improved.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present utility model.
