In addition, the support assembly 11 can bear acting force applied by objects such as air flow, ice blocks, stones and the like together with the guide plate 13 and the inspection door 15, so that the impact resistance and impact resistance of the flow guide device 1 are improved, and the protection effect of the flow guide device 1 is further improved.

In one possible implementation, as shown in fig. 1 and 4, two adjacent inspection doors 15 are connected to each other, so as to facilitate the installation reliability of the inspection doors 15 and to improve the carrying capacity of the inspection doors 15. Illustratively, the edge of one of the two adjacent inspection doors 15 is provided with at least one protrusion, and the edge of the other inspection door 15 is provided with a groove matched with the protrusion. For example, the right edge of one of the inspection doors 15 is provided with two protrusions protruding rightward, and the left edge of the adjacent inspection door 15 is provided with two grooves that mate with the protrusions. In addition, two adjacent inspection doors 15 can be in sealing fit, for example, a sealing gasket or a sealant is disposed between two adjacent inspection doors 15 to prevent air flow, ice, stones, etc. from passing through the gap between the adjacent inspection doors 15.

Alternatively, the surface of the inspection door 15 may be provided with a plurality of reinforcing ribs 151 for improving the strength of the inspection door 15, thereby improving the impact and shock resistance of the inspection door 15. A plurality of reinforcing ribs 151 may be provided at the front surface of the inspection door 15, and/or a plurality of reinforcing ribs 151 may be provided at the rear surface of the inspection door 15.

Wherein the length of the inspection door 15 having a relatively large surface area may be greater than the remaining inspection doors 15.

In one possible implementation, as shown in fig. 2, the bracket assembly 11 has a bracket body that includes a plurality of cross members 111, two side members 112, and at least one center member 113. The two side members 112 are connected to both ends of the plurality of cross members 111, respectively; one of the side members 112 is connected to the left ends of the plurality of cross members 111, respectively, and the other side member 112 is connected to the right ends of the plurality of cross members 111, respectively. The middle beam 113 is connected with the plurality of cross beams 111, the middle beam 113 is located between the two side beams 112, and the middle beam 113 and the side beams 112 are distributed at intervals. In this way, by providing the criss-cross member 111, the side members 112, and the center member 113, the strength of the bracket assembly 11 is improved, the bearing capacity of the bracket assembly 11 is improved, and the impact resistance of the deflector 1 are improved.

The number of the middle beams 113 may be multiple, and the multiple middle beams 113 are distributed at intervals, so as to facilitate the uniform stress of each middle beam 113 and the cross beam 111. At least a portion of the plurality of intermediate beams 113 are disposed perpendicular to the cross beam 111. In some examples, each intermediate beam 113 is disposed perpendicular to the cross beam 111. In other examples, there are portions of the central beam 113 that are perpendicular to the cross beam 111 and other portions of the central beam 113 that are at an angle less than 90 degrees from the cross beam 111.

The two rows of cross beams 111 are arranged at intervals up and down. There may be more than one beam 111 per row. Two adjacent cross beams 111 in the upper row of cross beams 111 can be connected through a longer middle beam 113, and two adjacent cross beams 111 in the lower row of cross beams 111 are also connected through a longer middle beam 113; that is, the upper end of the longer intermediate beam 113 is used to connect two adjacent cross beams 111, and the lower end of the longer intermediate beam 113 is used to connect two adjacent cross beams 111. The upper and lower cross beams 111 may be connected by a shorter intermediate beam 113. In this way, the stress on each intermediate beam 113 and the cross beam 111 is uniform, and the strength of the bracket assembly 11 can be further improved, so that the bearing capacity of the flow guiding device 1 is further improved.

Optionally, an upper connecting beam 114 is connected to the upper ends of the side beams 112 and at least a part of the center beam 113, and the upper connecting beam 114 is used for connecting with the underframe 21 of the vehicle body. The upper connection beam 114 may be connected to the upper ends of the two side beams 112 and to the upper end of the longer center beam 113. The baffle 13 may also extend to the upper connecting beam 114. The upper connecting beam 114 can be connected with the underframe 21 of the vehicle body through a plurality of bolts distributed at intervals; a plurality of bolts may be spaced to facilitate uniformity in the force applied to the upper tie beam 114. The upper connecting beam 114 can be connected with the underframe 21 in a sealing way; for example, the upper coupling beams 114 are coupled to the bottom chassis 21 by gaskets or sealants to prevent air flow, ice, stones, etc. from passing through the gap between the upper coupling beams 114 and the bottom chassis 21.

In some examples, the upper connecting beam 114 is disposed obliquely with respect to the side beam 112 and the middle beam 113, the side beam 112 and the middle beam 113 are in the same plane, and the angle between the upper connecting beam 114 and the plane bracket can be set according to actual needs, so that one surface of the upper connecting beam 114 can contact with the underframe 21, and the disposition of the side beam 112 and the middle beam 113 is also facilitated.

The lower ends of the side members 112 and at least a part of the center member 113 are connected to a lower connection member 115, and the lower connection member 115 is connected to the front end assembly 22 of the vehicle body. The lower connection beam 115 may be connected to lower ends of the two side beams 112 and to lower ends of the longer center beam 113. The baffle 13 may also extend to the lower connecting beam 115. In some examples, the lower connecting beam 115 may be directly connected to the underside of the front surface of the front end assembly 22. The lower connecting beam 115 can be connected with the front end assembly 22 of the vehicle body through a plurality of bolts distributed at intervals; a plurality of bolts may be spaced apart to facilitate uniformity in the force applied to the lower tie beam 115. The lower tie beam 115 may be sealingly connected to the front end assembly 22 by a gasket or sealant.

The lower connecting beam 115 is disposed obliquely with respect to the side beams 112 and the center beam 113. The side beams 112 and the center beam 113 are in the same plane, and the angle between the lower connecting beam 115 and the plane bracket can be set according to actual needs, so that one surface of the lower connecting beam 115 can be in contact with the front end assembly 22, and the side beams 112 and the center beam 113 can be conveniently arranged.

It is understood that a surface of the upper coupling beam 114 may be parallel to the lower surface of the base frame 21; a surface of the lower connecting beam may be parallel to the underside of the front surface of the front end assembly 22. The center sill 113 and the side sill 112 are connected between the upper connecting sill 114/the lower connecting sill 115. When the air guiding device 1 is assembled to the vehicle body, the center sill 113 and the side sill 112 are disposed to be inclined with respect to the vertical plane, and accordingly, the spoiler 13 disposed on the surfaces of the center sill 113 and the side sill 112 is also disposed to be inclined, for example, the center sill 113, the side sill 112, and the spoiler 13 are gradually inclined rearward from the top to the bottom.

In one possible implementation, as shown in fig. 4 to 8, the lower connecting beam 115 of the support assembly 11 may be connected with the supporting beam 17, and the supporting beam 17 may be connected with the front end assembly 22. The support beam 17 may be welded to the front end assembly 22 or attached by a plurality of bolts. Relative motion can have between lower tie-beam 115 and the supporting beam 17 for the adaptation front end constitutes 22, and does benefit to and reduces the position requirement to front end constitutes 22, can compensate certain machining error or assembly error, can also guarantee assembly quality. For example, the support beam 17 may be disposed at a predetermined area of the front end assembly 22 to reduce the influence on the components in the front end assembly 22; when the front end assembly 22 has a machining error or the front end assembly 22 has an assembly error with respect to the vehicle body, the deflector 1 can be connected to the front end assembly 22 by moving the lower connecting beam 115 with respect to the support beam 17.

As shown in fig. 9 and 10, in some examples, the lower connecting beam 115 is slidable in a lateral direction, that is, a left-right direction, with respect to the support beam 17. Illustratively, the axial direction of the support beam 17 is parallel to the transverse direction. The supporting beam 17 is a hollow beam, namely the supporting beam 17 is provided with a central hole which penetrates along the axial direction; the front surface of the support beam 17 is provided with a first slide groove 171 extending in the axial direction of the support beam 17; a sliding block 172 capable of sliding along the axial direction and a bolt 173 penetrating through the sliding block are arranged in the central hole, and the bolt 173 can extend out of the first sliding groove 171 and is connected with the bracket assembly 11. Thus, the lower connecting beam 115 can transversely slide relative to the support beam 17 by the sliding block 172 and the bolt 173 along the axial direction of the support beam 17, so that a certain allowance is provided for the transverse direction, certain processing errors and assembly errors are allowed to exist in the transverse direction of the flow guide device 1, the front end assembly 22 and the like, and the assembly difficulty of the front end assembly 22, the flow guide device 1 and the vehicle body underframe 21 is favorably reduced.

The lower connection beam 115 is slidable in a vertical direction, that is, an up-down direction, with respect to the support beam 17. For example, as shown in fig. 11, the lower connection beam 115 may be provided with a first long hole 116 extending up and down, that is, the length direction of the first long hole 116 is parallel to the up-down direction; the bolt 173 can also pass through the first long hole 116 and cooperate with a nut provided on a side of the lower connection beam 115 facing away from the support beam 17, so as to fasten and connect the lower connection beam 115 to the support beam 17 by the cooperation of the nut and the bolt 173. Additionally, a spacer may be disposed between the nut and the lower tie beam 115. The number of the first long holes 116 may be plural, and the number of the first long holes 116 may be adapted to the number of bolts connecting the lower connecting beam and the support beam 17. Like this, through the bolt 173 in first slot hole 116 up-and-down slip, lower tie-beam 115 can be for supporting beam 17 up-and-down slip to for vertical direction provides certain surplus, allow that certain machining error, assembly error exist along vertical direction such as guiding device 1, front end component 22, do benefit to and reduce the assembly degree of difficulty that front end component 22, guiding device 1 and automobile body chassis 21 were constituteed.

In other examples, the lower connecting beam 115 may slide vertically, i.e., up and down, relative to the support beam 17. Illustratively, the axial direction of the support beam 17 is parallel to the transverse direction. The supporting beam 17 is a hollow beam, namely the supporting beam 17 is provided with a central hole which penetrates along the axial direction; the front surface of the support beam 17 is provided with a plurality of second sliding grooves, the length direction (i.e., the extending direction) of which is parallel to the vertical direction. The central hole is internally provided with a sliding block which can slide along the length direction of the second sliding groove and a bolt which is arranged in the second sliding block in a penetrating way, and the bolt can extend out of the second sliding groove and is connected with the support component 11. The number of the second sliding grooves can be matched with the number of bolts connecting the lower connecting beam with the supporting beam 17.
