FIG. 3 is a partial schematic view of the present invention at the junction;
the items in the figure are respectively: 1 supporting beam, 2 supporting plane, 3 bottom plate, 4 auxiliary beam, 5 foaming sandwich, 6 connecting part, 61 sink groove, 62 connecting hole and 63 cladding plate.
Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
as shown in fig. 1, 2, 3 a light-weight commodity circulation car packing box floorbar, including many interval vertically and horizontally staggered settings be rectangular grid structure's a supporting beam 1 (the quantity and the interval of a supporting beam 1 of violently indulging two kinds of directions can be adjusted according to actual production demand, can satisfy the carrying demand of weighing can), the junction between each supporting beam 1 is the looks through connection, in order to realize being located the coplanar between horizontal and fore-and-aft supporting beam in order to reduce whole height, and the structure that passes through mutually makes the junction not have the seam, structures such as solder joint, the atress is more even stable. The upper surfaces of all the supporting beams 1 are positioned on a same horizontal supporting plane 2, and a bottom plate 3 positioned on the upper surfaces of the supporting beams 1 is arranged in the supporting plane 2. The supporting beam 1 and the bottom plate 3 in the embodiment are the supporting beam 1 and the bottom plate 3 made of carbon fiber composite materials, and are integrally manufactured through an RTM vacuum forming process, so that the forming can be realized without welding and bonding, the processing is convenient, and the integration degree is high. When the cargo box is arranged on the logistics vehicle and bears the cargo box above, the whole load is dispersed by the bottom beams, and the fiber characteristics and the tensile strength of the carbon fiber composite material enable the load to be dispersed uniformly, so that the problems of stress concentration and the like are basically eliminated.
In this embodiment, the bottom plate 3 is formed to extend from the upper surface of the support beam 1 to both sides in the width direction of the support beam 1 and has a thin plate structure wider than the support beam 1 therebelow, which improves the supporting area and the supporting effect for supporting the cargo box of the logistics vehicle thereabove by a small thickness, and has a good structural strength because it is integrally produced with the support beam 1.
In this embodiment, the bottom plate 3 is connected in an arc at the joint of the two criss-cross support beams 1, so that the problem of stress concentration of the bottom plate 3 at the criss-cross joint is reduced by the arc structure, and meanwhile, the bottom plate 3 is used as a connection transfer structure between the cargo box of the logistics vehicle and the support beam 1, and the cargo box effectively disperses the load of the cargo box on the support beam 1 under a smaller weight increment due to a larger area obtained by the arc connection.
In this embodiment, the vertical thickness of the transversely disposed supporting beam 1 gradually decreases from the center to both sides, and referring to fig. 2, the cross section of the transversely disposed supporting beam 1 is in an inverted isosceles trapezoid shape, so that the supporting beam has a good supporting performance from the center to both sides, and the overall weight is further reduced.
In this embodiment, the tip that is located the horizontal supporting beam 1 that sets up of homonymy passes through vice roof beam 4 body coupling, and vice roof beam 4 is also made for carbon-fibre composite as being located the roof beam body of packing box edge downside, and the middle part of the relative whole floorbar of atress is less here, so adopt comparatively little cross-section volume and set up to be the approximate U-shaped of top open-ended and further subtract heavy when satisfying the marginal support performance, and its top open-ended structure makes the bottom edge of packing box can realize the card and go on effectually spacingly simultaneously.
In the present embodiment, the cross section of the support beam 1 is a hollow rectangle to realize load bearing in a rectangular shape, and weight reduction is realized by the hollow inside.
In this embodiment, the support beam 1 is filled with the foamed core 5 formed of a foamed organic material, so that the strength and the shearing force can be increased.
In this embodiment, the upper surface and the lower surface of the support beam 1 are provided with the connecting portions 6, the connecting portions 6 are used for realizing the bolt/bolt connection between the bottom beam and the chassis and/or the cargo box of the logistics vehicle, and the corresponding connecting portions 6 can be adaptively cancelled in the model that the connecting form is not required.
Referring to fig. 3, in the present embodiment, the connecting portion 6 includes a sinking groove 61 formed on an inner wall surface of the supporting beam 1 during integral forming, and a connecting hole 62 penetrated through the sinking groove 61 outward, a covering plate 63 is attached to a notch of the sinking groove 61, a surface of the attached covering plate is flush with the inner wall surface of the supporting beam 1 to form a surface continuous and flat with the periphery, a matching structure such as a screw thread, a nut or a pin bush for connection may be provided in an inner wall of the connecting hole 62 or a middle between the covering plate 63 and the sinking groove 61 according to design requirements, for example, in the present embodiment, a nut embedded inside may be provided, the periphery of the nut is surrounded and fixed during production through a carbon fiber composite material, and when the nut is mounted to a chassis of a logistics vehicle, a bolt may be screwed from bottom to top to achieve stable connection.
The above embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention, and various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention fall into the protection scope of the present invention, and the technical contents of the present invention which are claimed are all described in the claims.
