In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.
As shown in fig. 1 to 3, the present disclosure provides a front bleed air duct assembly which includes a duct body 1 for circulating air and a first connecting portion for connecting with a vehicle body sheet metal 2, the first connecting portion including a mounting bracket 4, the mounting bracket 4 being pivotably connected with the duct body 1 by a pivot shaft, and enabling the duct body 1 and the mounting bracket 4 to generate a relative movement in an axial direction of the pivot shaft. The length of the pivot shaft can be designed to be a certain axial length after the mounting bracket 4 and the tube body 1 are mounted, so that the tube body 1 and the mounting bracket 4 can move relatively in the axial direction.
Through the technical scheme, the vehicle is at the operation in-process, thereby empty filter 3 can produce vibrations and produce the displacement and transmit body 1 to preceding bleed air pipe, and this displacement can be decomposed into the ascending displacement in all directions, can make body 1 rotate round the pivotal axis through setting up the pivotal axis, and the pivotal axis design becomes and to allow body 1 along the axial displacement of pivotal axis, thereby make body 1 installing support 4 relatively, and then rotate and remove relatively automobile body panel beating 2, decompose and offset with the vibrations that empty filter 3 produced through this rotation and removal, avoid body 1 to receive the stress too big and damage. Moreover, the structure of the mounting bracket 4 can also compensate the manufacturing errors of the vehicle body metal plate 2 and the air filter 3 during mounting, thereby avoiding the damage caused by the stress generated by the pipe body 1.
In the embodiment of the present disclosure, as shown in fig. 1 to 3, the lug 11 may be formed on the pipe body 1 in a protruding manner, and the mounting bracket 4 may include a U-shaped block 42 having an opening, the lug 11 is disposed in the opening, and the pivot shaft penetrates through two side walls of the U-shaped block 42 and the lug 11, that is, the lug 11 and the U-shaped block 42 may relatively move along the axial direction of the pivot shaft. When the lug 11 moves along the axial direction of the pivot shaft to abut against one side wall of the U-shaped block 42, the side wall of the U-shaped block 42 can axially limit the lug 11 to avoid the over-displacement of the pipe body 1. The distance between the two side walls of the U-shaped block 42 can be designed according to the limit values that the tubular body 1 can be moved in practice, in order to guarantee the reliability of the front bleed air duct assembly.
In an embodiment, two lugs 11 arranged at intervals are formed on the pipe body 1, the two lugs 11 can disperse the connection stress of the pipe body 1 and the mounting bracket 4, and the damage caused by the stress concentration at the joint is avoided, in this case, the mounting bracket 4 can comprise two U-shaped blocks 42 and a mounting plate 41 for connecting the two U-shaped blocks 42, and the mounting plate 41 is connected with the vehicle body metal plate 2.
