The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1:
as shown in fig. 1 to 2: a rail transit body skirt, comprising:
the outer skin 1 is positioned on the outer side of the vehicle body, and is used for coating the vehicle body;
the outer skin comprises a first bending structure 2 and a second bending structure 3, wherein the first bending structure 2 and the second bending structure 3 are fixedly arranged on an outer skin 1 and comprise a vertical end 21, a gap is formed between the two vertical ends 21 and the outer skin 1, mounting holes 22 are formed in the two vertical ends 21, bolt structures are arranged at the mounting holes 22, and connecting structures are fixed on the apron boards through the bolt structures;
wherein, first structure 2 and the second structure 3 of buckling set up horizontally, and in the predetermined distance of interval in the vertical direction.
Through setting up outer covering 1, first structure 2 and the second structure 3 of buckling, first structure 2 and the 3 level settings of the second structure of buckling, and interval predetermined distance in vertical direction, first structure 2 and the second of buckling includes a vertical end 21 on the structure 3 respectively, be provided with mounting hole 22 on two vertical ends 21, mounting hole 22 department is provided with the bolt structure, the binding structure is fixed in on the skirtboard through the bolt structure, thereby need not to carry out pre-buried to connection structure, only need behind the shaping of skirtboard plate body, through the bolt fastening can on the skirtboard, avoided leading to the erection dimension discrepancy at pre-buried in-process offset, guarantee product quality.
In the present embodiment, the top end of the outer skin 1 in the vertical direction is provided with a hem structure 11 that is turned inside the vehicle body. Wherein, the first bending structure 2 is fixedly arranged on the edge folding structure 11, and the vertical end 21 extends downwards from the edge folding structure 11.
Because the skirtboard needs the upset, turn over outer skin 1 to the automobile body internal book with the top of skirtboard, thereby be located the automobile body with hem structure 11 of here, play better safeguard effect, simultaneously, with the fixed setting of first structure 2 of buckling on hem structure 11, vertical end 21 extends downwards from hem structure 11, utilize the structure of here, make the structure of first structure 2 of buckling and hem structure 11 constitution similar T type, utilize the distance of hem structure 11 internal book as the clearance, in order to satisfy the fixed demand of bolt.
Meanwhile, the second bending structure 3 is L-shaped, and one end thereof is fixedly connected with the outer skin 1, and the other end thereof is a vertical end 21. The second bending structure 3 is arranged to be L-shaped, so that under the condition that one end of the second bending structure is fixedly connected with the outer skin 1, the other end of the second bending structure is a vertical end 21, and a gap exists between the vertical end 21 and the outer skin 1, so that the fixing requirement of the bolt is met.
In the present embodiment, the mounting hole 22 is a kidney-shaped hole, and the kidney-shaped hole is horizontally or vertically disposed. For installation convenience, the installation hole 22 is a waist-shaped hole, so that the bolt can extend into the larger opening of the waist-shaped hole and then move to the smaller opening for locking.
Preferably, in the above embodiment, the skirt is of a pultruded integral structure.
Through setting up the skirtboard into pultrusion integrated into one piece structure to can draw first structure 2 and the second structure 3 and the hem structure 11 of buckling an organic whole and extrude, increase joint strength and structural strength.
Example 2:
as shown in fig. 3, different from embodiment 1, in this embodiment, the first bending structure 2 is L-shaped, and one end of the first bending structure is fixedly connected to the outer skin 1, and the other end of the first bending structure is a vertical end 21, the first bending structure 2 is disposed at the lower end of the edge folding structure 11, and a gap is formed between the vertical end 21 and the edge folding structure 11.
Wherein the vertical end 21 extends upwardly or downwardly.
Through setting up first structure 2 of buckling into the L type, wherein one end and 1 fixed connection of outer skin, the other end is vertical end 21, is the clearance between vertical end 21 and hem structure 11 to satisfy the bolt fastening demand.
Preferably, an inner skin 4 is arranged on the apron board, a plurality of cavities 41 are arranged between the inner skin 4 and the outer skin 1, and the second bending structure 3 is a cavity 41 structure on the inner skin 4 close to the first bending structure 2.
Because combined material skirtboard is when pultrusion, in order to guarantee structural strength, often be provided with interior skin 4, include a plurality of cavity 41 between interior skin 4 and the outer skin 1, form the structure of similar strengthening rib between cavity 41, promote the anti bending property and the heat preservation effect of skirtboard, so set up second bending mechanism to be close to the cavity 41 structure of first bending structure 2 on interior skin 4, when pultrusion, need not extra bending structure 3 to the second and design, only need the cavity 41 here punch can.
As shown in fig. 4, the present embodiment further includes a rail transit vehicle body skirt connection structure, including: hinge structure 5, hinge structure 5 is through on the bolt fastening is in track traffic automobile body skirtboard, hinge structure 5 includes stiff end 51 and extension end 52, extends end 52 and is located between first bending structure 2 and the second bending structure 3, and extends to the skin surface inwards, promptly, extends the surface of section 52 and contradicts with the skin surface, restricts hinge structure 5's rotation for the skirtboard is more stable when opening and shutting. One end of the fixed end 51 is lapped on the first bending structure 2, the other end is lapped on the second bending structure 3, and during specific connection, the fixed end 51 can be connected with the first bending structure 2 and the second bending structure 3 through bolts or can be bonded through structural glue.
As a preferred embodiment, when adopting bolted connection, the bolt slides to the mounting hole 22 along the recess in, and the mounting hole 22 bore diminishes gradually, and like this when connecting, the whole bolt of following is put into from big bore diameter department, moves to small bore department again, when easy to assemble, can also effectively prevent that the bolt from becoming flexible.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
