[0030] As shown in FIG. 1 to FIG. 5, according to an embodiment of
the present disclosure, a vehicle body structure is provided.
[0031] Specifically, as shown in FIG. 1, the vehicle body structure
includes: a vehicle body, an air duct 10 and a maintenance portion
13. The air duct 10 is disposed at the bottom of the vehicle body.
The air duct 10 has a maintenance port. The maintenance portion 13
is connected with the air duct 10 and located at the maintenance
port. The maintenance portion 13 has an opening position for
opening the maintenance port and a closing position for closing the
maintenance port.
[0032] In the present embodiment, a maintenance portion is provided
on an air duct at the bottom of a vehicle body. By operating the
maintenance portion, a maintenance port of the air duct is at an
opened or closing position, in order to detect or repair the
interior of the air duct, thus prolonging the life of the air duct
of the vehicle body structure and improving the reliability.
[0033] In the present embodiment, the air duct 10 includes a main
air duct 11 and a branch air duct 12. The main air duct 11 is
provided along a length direction of the vehicle body, and the
middle of the main air duct 11 is provided with an air supply
opening 111. The branch air duct 12 is provided along a width
direction of the vehicle body, a first end of the branch air duct
12 is communicated with the main air duct 11, and a second end of
the branch air duct 12 has an air outlet 121 for communicating with
the interior of the vehicle body. By connecting the branch air duct
to the main air duct, air generated by an air conditioner can be
delivered into the vehicle body through the branch air duct in all
directions, thereby improving the use experience of a user.
[0034] As shown in FIG. 1, the main air duct 11 or the branch air
duct 12 is provided with the maintenance portion 13. Of course,
both the main air duct 11 and the branch air duct 12 may be
provided with the maintenance portions 13. Such arrangement enables
the main air duct 11 and the branch air duct 12 to be detected or
repaired by the maintenance portions, thus prolonging the life of
the air duct of the vehicle body structure and improving the
reliability.
[0035] As shown in FIG. 2, the vehicle body structure further
includes a guide portion 20, the guide portion 20 being disposed in
the air duct 10 to guide or distribute airflow in the air duct 10.
Such arrangement avoids an eddy at the air supply opening, thus
improving the flowing stability of airflow in the air duct.

guide plate 21. The first guide plate 21 is disposed at the air
supply opening 111 and located in the air duct 10, and/or the first
guide plate 21 is disposed at a joint between the main air duct 11
and the branch air duct 12 and located in the air duct 10, wherein
the first guide plate 21 is a herringbone guide plate. The
herringbone guide plate distributes airflow at the air supply
opening and avoids an eddy, thus improving the flowing stability of
airflow in the air duct.
[0037] As shown in FIG. 2, FIG. 4 and FIG. 5, the second end,
provided with the air outlet 121, of the branch air duct 12 is an
arc-shaped structure, and the guide portion 20 includes a second
guide plate 22, the second guide plate 22 being disposed in the
second end of the branch air duct 12 to divide the second end of
the branch air duct 12 into at least two independent air outlet
ducts. The second guide plate here may be an arc-shaped guide
plate, and there is at least one arc-shaped guide plate. Such
arrangement enables the second guide plate namely the arc-shaped
guide plate to directionally guide airflow and avoids an eddy.
[0038] As shown in FIG. 1, the air supply opening 111 or the air
outlet 121 is provided with a flange 30. Of course, they may be
both provided with a flange. A seal ring is provided in the flange
30. Such arrangement achieves firm mounting of a pipeline
communicated with the air supply opening and the air outlet, and
good sealing performance.
[0039] In the present embodiment, there are multiple branch air
ducts 12, the multiple branch air ducts 12 being provided at
intervals along the length direction of the vehicle body. By
connecting the multiple branch air ducts to the main air duct, air
generated by an air conditioner can be delivered into the vehicle
body through the branch air duct in all directions, thereby
improving the use experience of a user.
[0040] In the present embodiment, the multiple branch air ducts 12
are symmetrically disposed on two sides of the main air duct 11.
Such arrangement facilitates mounting of the branch air duct 12,
and improves the stability of airflow in the air duct.
[0041] As shown in FIG. 1, the air duct 10 includes a return air
duct 14. A first end of the return air duct 14 is communicated with
the main air duct 11, and a second end of the return air duct 14 is
communicated with the interior of the vehicle body. At least one
end of the return air duct is provided with a flange, in order to
mount the return air duct. Such arrangement enables interior
airflow in the vehicle body to return into the air conditioner
through the return air duct.
[0042] In the present embodiment, the maintenance portion 13 is a
maintenance cover plate. The maintenance cover plate is detachably
disposed at the maintenance port. The maintenance cover plate is
connected to a pipeline wall on the periphery of the maintenance
port in a fastening connection manner, and a rubber pad is disposed
in the maintenance cover plate to improve the sealing performance
of connection between the maintenance cover plate and the
maintenance port.
