As shown in fig. 1 to 5: a composite vehicular transition plate comprising:
the longitudinal ribs 1 are arranged along a direction perpendicular to the length extension direction;
the two transverse ribs 2 are respectively arranged at two ends of the plurality of longitudinal ribs 1 in the length direction and are fixedly connected with the end parts of the plurality of longitudinal ribs 1;
the filling structure 3 is arranged between the two longitudinal ribs 1, and the dislocation of the longitudinal ribs 1 along the arrangement direction is limited;
the outer skin 4 is used for coating one end of the longitudinal ribs 1, the two transverse ribs 2 and the filling structure 3 in the thickness direction.
Through setting up a plurality of muscle 1 of indulging, two horizontal muscle 2, filling structure 3 and outer skin 4, a plurality of muscle 1 of indulging is arranged along the direction that perpendicular to length extends, two horizontal muscle 2 set up respectively at a plurality of both ends of indulging 1 length direction of muscle, thereby form a frame, outer skin 4 wraps the wherein one end of thickness direction, form the plate body structure, outer skin 4 is for supporting the people in the one end of thickness cladding, the one end surface of goods, filling structure 3 sets up indulges between the muscle 1, come the restriction to indulge the dislocation of muscle 1 along the array orientation, guarantee the structural strength of cab apron, wherein indulge muscle 1 and horizontal muscle 2 and be combined material, when satisfying the bearing structure intensity of transition board, the weight that has significantly reduced, the lightweight demand has been satisfied.
In this embodiment, the longitudinal rib 1 is a bent structure, and a first folded edge 11 and a second folded edge 12 are disposed along the length extending direction, and an included angle between the first folded edge 11 and the second folded edge 12 is smaller than 180 ° at an end far away from the covering of the outer skin 4.
Because there is often a difference in height between train carriage plane and the platform plane, so the cab apron often is the structure of buckling, adapts to the difference in height of two places, through will indulge muscle 1 and set up the structure of buckling, including first hem 11 and second hem 12, first hem 11 is less than 180 with second hem 12 keeping away from the one end contained angle of outer skin 4 cladding to and upwards hunch up in outer skin 4 department, form the transition of height.
Wherein, for the transition of messenger's height more smooth-going and nature, be provided with arc structure 13 between first hem 11 and second hem 12, arc structure 13 both ends are connected with first hem 11 and second hem 12 respectively to be the arc in hunch-up department, make things convenient for people's walking or wheel body to pass through on the cab apron.
Preferably, the longitudinal ribs 1 are provided with transverse reinforcing structures 21 at the arc structures 13, the transverse reinforcing structures 21 are arranged at one ends of the longitudinal ribs 1, which are far away from the outer skin 4, and the transverse reinforcing structures 21 are arranged at the arc structures 13 to reinforce the arc structures 13.
Because the shape of the transition plate is arched upwards, the load between the first folding edge 11 and the second folding edge 12 is large, and in order to ensure the structural strength of the transition plate, a transverse reinforcing structure 21 is arranged at the arc-shaped structure 13, and the transverse reinforcing structure 21 is arranged at one end of the longitudinal rib 1, which is far away from the coating of the outer skin 4, so that the bottom of the arc-shaped structure 13 is supported, and the structural strength and the service life of the transition plate are ensured.
When filling between the longitudinal ribs 1 by using the filling structure 3, all the spaces between the longitudinal ribs 1 may not be filled completely, but the filling structure 3 fills at least the portion of the arc-shaped structure 13 between the longitudinal ribs 1, and the shape of the filling structure 3 at the portion of the arc-shaped structure 13 is the same as that of the arc-shaped structure 13.
Wherein, filling structure 3 indulges 1 length extending direction's of muscle wherein one end with indulge muscle 1 laminating, the vacancy is reserved to the other end, can play better subtract heavy effect, how much of vacancy can carry out adaptability adjustment according to the load, if the load is less, can be with the bigger some that the vacancy set up, if the load is great, then the vacancy then need be set up less, even fill completely.
When using outer skin 4 to indulge muscle 1, horizontal muscle 2 and filling structure 3 and cladding, owing to need will indulge muscle 1 through outer skin 4, horizontal muscle 2 and filling structure 3 form a whole, so can only to indulge muscle 1, horizontal muscle 2 and filling structure 3 thickness direction wherein one end cladding, the other end adopts local cladding's mode, and outer skin 4 is indulging the other end of muscle 1 thickness direction, will wrap horizontal additional strengthening 21's part at least, prevent breaking away from of horizontal additional strengthening 21.
Indulge between muscle 1 and the horizontal additional strengthening 21, need bond, outer skin 4 also need to adopt the bonding to fix with indulging muscle 1, horizontal muscle 2 and filling structure 3 laminating department, also need to adopt the bonding to fix indulging muscle 1 and filling structure 3 laminating department.
When fixing the longitudinal bars 1 and the transverse bars 2 at two ends, if the load is small, the end parts of the longitudinal bars 1 can be respectively attached to the side walls of the transverse bars 2, and the attaching positions are fixed in a bonding mode.
If the load is great, when satisfying structural strength's demand that can not be fine through the mode of bonding, can be provided with a plurality of flutings at 2 lateral walls of horizontal muscle this moment, a plurality of muscle 1 of indulging pass through the fluting, insert horizontal muscle 2 in, increase stability and structural strength of connecting.
As the optimization of above-mentioned embodiment, filling structure 3 is the foam structure, through setting up filling structure 3 to the foam structure, can play the effect of supporting and stereotyping on the one hand, and on the other hand adopts the foam to fill, the holistic weight of lightening that can be better, indulge muscle 1 can adopt the mode of preimpregnation material parcel foam, outer skin 4 also adopts preimpregnation material, bond earlier, the mode that later adopted whole curing moulding, horizontal muscle 2 can adopt pultrusion tubular product, can set up to hollow structure, also can set up to the foam and fill, installation hinge structure department on horizontal muscle 2, can fill the reinforcement piece, increase structural strength.
It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
