Abstract
Description
Technical Field
[0001] This utility model relates to a skirt panel, and more particularly to an aluminum honeycomb skirt panel for rail transit vehicles. Background Technology
[0002] Currently, with the increasing operating speed of rail transit vehicles, in order to save space inside the carriages and facilitate the installation and configuration of electrical wiring and air ducts, rail transit vehicles typically install and arrange vehicle equipment under the car body underframe. Skirts can completely cover the bogies, undercarriage electrical and braking equipment, etc., and enhance the vehicle's aesthetics. They are an important component of the undercarriage structure of rail transit vehicles. In addition, rail transit vehicles generate strong air pressure waves when running at high speeds on the track. Therefore, objects such as gravel, sand, and ice can impact the equipment under the vehicle at high speed. The skirts effectively reduce air resistance, protect the equipment under the vehicle, facilitate equipment maintenance, and ensure the safe operation of the vehicle.
[0003] The aluminum honeycomb is an aluminum alloy composite panel. The entire processing of the aluminum honeycomb panel is completed in a modern factory using brazing forming technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized. There are small holes on the honeycomb aluminum skin, which allows the gas inside the panel to flow freely. The sliding installation buckle system will not cause structural deformation during thermal expansion and contraction. Utility Model Content

The upper end of the skirt body is connected to the first connecting rod via a first hinge, and the lower end is connected to the second connecting rod via a second hinge. The first connecting rod is fixedly connected to the skirt bracket 6 by bolts. The end of the first connecting rod away from the first hinge is bent upward to form a bent portion, and the bent portion matches the side shape of the skirt bracket. The second connecting rod is threaded and fixedly connected to the equipment compartment frame by a nut.
[0006] The upper end of the skirt panel body is provided with at least two first connecting rods according to the width of the skirt panel body; the lower end of the skirt panel body is provided with at least two second connecting rods according to the width of the skirt panel body.
[0007] The upper part of the first connecting rod is provided with a rubber pad, and it is fixedly connected to the skirt plate bracket by at least two sets of bolts.
[0008] A rubber pad is also provided on the side of the bent part near the skirt board support.

Attached Figure Description
[0016] Figure 1 This is a structural schematic diagram of the aluminum honeycomb skirt panel of the rail transit vehicle. Detailed Implementation
[0017] like Figure 1 As shown, the aluminum honeycomb skirt of the rail transit vehicle includes a skirt body 1, a first connecting rod 4, and a second connecting rod 14. The upper end of the skirt body 1 is connected to the first connecting rod 4 via a first hinge 3, and the lower end is connected to the second connecting rod 14 via a second hinge 12. The first connecting rod 4 is fixedly connected to the skirt support 6 by bolts. The end of the first connecting rod 4 away from the first hinge 3 is bent upward to form a bent portion 5, and the bent portion 5 matches the side shape of the skirt support 6. The second connecting rod 14 is threaded and fixedly connected to the equipment compartment frame 13 by nuts.
[0018] The skirt panel body 1 is made of aluminum honeycomb material, which can ensure hardness while being lighter in weight, has better impact resistance, is easy to weld, and has good shock absorption and noise reduction effects.
[0019] At the upper end of the skirt panel body 1, at least two first connecting rods 4 are provided according to the width of the skirt panel body 1. A rubber pad 7 is provided on the upper part of each first connecting rod 4. The first connecting rod 4 is fixedly connected to the skirt panel bracket 6 by at least two sets of bolts. Both the first connecting rod 4 and the skirt panel bracket 6 are provided with screw holes for installing bolts. In this embodiment, the bolts include a first bolt 8 and a second bolt 9. The first bolt 8 and the second bolt 9 pass through the rubber pad 7, continue downwards through the first connecting rod 4, and are then fixed with a nut.
[0020] Furthermore, a rubber pad is also provided on the side of the bent part 5 near the skirt board bracket 6. When the first connecting rod 4 is fixed to the bottom of the skirt board bracket 6 by bolts, the bent part 5 contacts the side of the skirt board bracket 6.
[0021] Furthermore, a sealing strip 10 is provided on the outer side of the skirt support 6, and the top of the skirt body 1 extends upward to form a shielding part. The shielding part is provided with a T-shaped connector 11 that is inserted into the sealing strip 10 to protect the gap between the skirt body 1 and the skirt support 6. Furthermore, the side of the skirt body 1 closest to the rail transit vehicle, that is, the inner side, is covered with sound insulation cotton 2.
[0022] At the lower end of the skirt panel body 1, at least two second connecting rods 14 are provided according to the width of the skirt panel body 1. The outer side panel of the equipment compartment frame 13 is provided with a first through hole for inserting the second connecting rods 14. After the second connecting rod 14 is inserted into the first through hole, it is fixed using a first nut 15. Thus, the outer side of the first through hole of the equipment compartment frame 13 is the second hinge 12, and the inner side is the first nut 15, achieving fixation of the skirt panel body 1. Furthermore, washers are installed between the first nut 15 and the first through hole, and between the first through hole and the second hinge 12, to achieve a fastening effect.
[0023] After passing through the first through hole and the first nut 15, the second connecting rod 14 passes through the rubber layer 14 of the sound insulation panel of the equipment compartment frame 13. The rubber layer 14 is provided with a second through hole, through which the second connecting rod 14 passes, and is then fixed with the second nut 16. This dual fixing method of the first nut 15 and the second nut 16 achieves the fixation of the skirt panel body 1, and, combined with the arrangement of the rubber layer 14 of the equipment compartment frame 13, further sound insulation can be achieved.
[0024] As can be seen, the rubber pads 7 and rubber layer 14 effectively prevent noise generated by the skirt panel body 1. The two connecting rods effectively secure the skirt panel.
[0025] The present invention has the following advantages: (1) The skirt is fixedly connected to the rail transit vehicle by the connecting rod. By fixing the connecting rod, the skirt can be effectively fixed and supported; (2) The connecting rod is provided with a rubber pad, and the skirt is provided with sound insulation cotton, which can achieve a quieter effect.
