Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It is noted that relative terms such as "first," "second," and the like may be used to describe various components, but these terms are not intended to limit the components. These terms are only used to distinguish one component from another component. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and/or" refers to a combination of any one or more of the associated items and the descriptive items.
As shown in fig. 1, fig. 1 is a prior art exhaust hook mounting bracket for an automobile mentioned in the background art, and a developed automobile type exhaust hook bracket has the technical problem that the dynamic stiffness performance of an exhaust pipe hook mounting point is low, and does not meet the NVH performance requirement of the automobile. An existing front floor 103, an existing exhaust hook 100, an existing exhaust hook reinforcement plate 101, an existing exhaust hanger lower support hook 105, an existing front floor left stringer 104, and an existing center tunnel left stringer 102.
As shown in fig. 2, fig. 2 is the utility model discloses a structural schematic diagram of automobile exhaust lifting hook installing support, the utility model discloses an automobile exhaust lifting hook installing support, including preceding floor 10, set up well passageway left longitudinal beam 14, first stationary blade 12, first exhaust lifting hook reinforcing plate 13 and exhaust lifting hook 11 on preceding floor 10, exhaust lifting hook 11 sets up on preceding floor 10 through first exhaust lifting hook reinforcing plate 13, and first stationary blade 12 is connected with exhaust lifting hook reinforcing plate 13, and first stationary blade 12 bottom welds on preceding floor 10. The automobile exhaust lifting hook mounting bracket of the utility model has the advantages that the dynamic stiffness performance is improved, the dynamic stiffness in the X direction and the dynamic stiffness in the Z direction are both obviously improved, and the aim is achieved, wherein the lifting range of the dynamic stiffness in the Z direction is all up to more than 130% (Table 1); specifically, the structure strengthens the local mode and the strength at the mounting point, and further improves the dynamic stiffness at the mounting point of the exhaust pipe lifting hook; meanwhile, the structure can inhibit the vibration transfer function of the steering wheel, the excitation on the steering wheel is reduced in the whole vehicle state, and the risk of the problem of overlarge vibration of the steering wheel can be reduced. Where 16 denotes a front floor left side member.
As shown in table 1, table 1 is a dynamic stiffness performance analysis table;
TABLE 1
As shown in table 2, table 2 shows the vibration transfer function analysis results.
TABLE 2
As shown in fig. 2, preferably, the first fixing piece is connected to the periphery of the exhaust hook reinforcing plate; namely, the first fixing piece is arc-shaped and surrounds and connects the peripheries of the exhaust lifting hook reinforcing plates.
As shown in fig. 4 and 5, the exhaust hook is preferably further provided on the center tunnel left side member 14 through a second exhaust hook reinforcing plate 17, which is provided with a space 30 therebetween. Intervals are reserved at non-welding points of the reinforcing plate, so that the reinforcing plate is formed into a reinforcing rib shape, the matching difficulty of parts is reduced, electrophoresis liquid drainage and exhaust are facilitated, and the corrosion resistance of the parts is enhanced; and the second exhaust hook reinforcing plate is welded on the middle channel left longitudinal beam.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
