The structure can ensure that the lap joints of the adjacent apron boards are not light-tight, each lap joint can be staggered in a proper amount along the assembly length direction of the carriage, and the structure can provide the total assembly length (W) for the whole row of carriages1+W2-3mm) to improve the aesthetics of the seam after assembly and at the same time improve the ease of assembly. Because the lap joint has no physical contact, the noise generated when the vehicle jolts in the running process is avoided.
Description
Technical Field
The invention discloses a light-tight lap joint structure of an upper skirt plate made of a composite material of a railway vehicle, and belongs to the technical field of product structures.
Background
The apron board on the traditional rail vehicle is of a steel structure, and each carriage is formed by connecting a plurality of upper apron boards. In recent years, with the continuous innovation of the technology in the rail transit industry, the requirement for light weight of materials is more and more remarkable. The modification of the car body structure by adopting the honeycomb sandwich composite material is an important direction for reducing the weight of the railway car. After the upper apron board made of the composite material is formed, the upper apron board is assembled through processes of profile modification, paint spraying and the like, and the difference of the flatness of the side faces of the two adjacent upper apron boards often causes a gap to be formed at the butt joint part, so that the upper apron board is partially transparent. The method has the defects that the visible surface at the connecting part of the upper skirt plate is exposed black, the attractiveness is poor, the foam is easy to damage, loosen and slide off when a train runs at a high speed and jolts violently, and the durability is poor.
Disclosure of Invention
The invention provides a light-tight lap joint structure of an upper apron board of a composite material of a railway vehicle, which is designed and provided aiming at solving the problem of local light transmission caused by a gap at the side joint of the adjacent upper apron boards.
The technical solution of the invention is as follows:
in this kind of rail vehicle combined material goes up the lighttight overlap joint structure of apron, two adjacent last skirts I1, go up II 2 of apron and dock its characterized in that with the stile I3, the II 4 docks in stile of side: the bottom in the I3 outside of stile, along the outward appearance edge of last apron I1 set up a long overlap edge 5, and this long overlap edge 5 forms "L" type structure with stile I3, on II 4 lateral surfaces of stile, sets up a short overlap edge 6 along the middle part position, and this short overlap edge 6 forms "T" type structure with the surface of stile II 4.
In one implementation, the short overlapping edge 6 is equally spaced from the bottom edge of the stile II 4.
In one embodiment, the long overlapping edge 5 has a width W1The width of the short overlapping edge 6 is W2The two satisfy the following relational expression: w is not less than 2mm2≤W1≤20mm。
In one implementation, during assembly, a gap is reserved between the end face of the long overlapping edge 5 and the vertical edge II 4 of the upper apron plate II 2, a gap is reserved between the short overlapping edge 6 and the vertical edge I3 of the apron plate I1, and the gaps at the two positions are larger than 1 mm.
In one embodiment, the width of the overlapping portion of the projections of the long and short overlapping sides 5 and 6 in the thickness direction is set to the shielding width W3The shielding width W3Greater than 3 mm.
In one embodiment, the spacing between the upper end face of the long overlapping edge 5 and the lower end face of the short overlapping edge 6 is greater than 5mm, this spacing being equal to the thickness H of the long overlapping edge 51Thickness H of the short overlapping edge 62The sum of the height of the vertical edges of the upper apron board and the height of the vertical edges of the lower apron board are not more than the height of the vertical edges of the upper apron board.
The invention is structured inOn the premise of ensuring light-tight, each lap joint can be staggered properly along the assembly length direction, and W can be provided for the installation length of the whole train1+W2A margin of 3mm, thus improving the aesthetics of the seam after assembly, while improving the ease of assembly. Because the lap joint has no physical contact, the noise generated when the vehicle jolts in the running process is avoided.
Wherein, in the L-shaped structure, the long overlapping edge 5 is integrally formed with the upper skirt plate 1 through a groove designed in a die, and the width W of the long overlapping edge is1And a thickness H1The size is ensured, the fillet at the edge of the upper skirt plate can be kept consistent, and the consistency of the visual effect at the seam of the adjacent upper skirt plates is ensured. In the T-shaped structure, the short overlapping edge 6 is formed and then bonded, the forming width and the thickness can be adjusted in time according to the assembling effect, and the process complexity of the integral forming of the short overlapping edge 6 is also avoided. The upper skirt plate lap joint structure adopting the structure can meet the requirements of rail transit train attractiveness and assembly convenience.
