Description

Lightweight EVA carbon fiber plywood Technical Field The utility model relates to the technical field of ss, in particular to a lightweight EVA carbon fiber plywood. Background The EVA carbon fiber glue board is a composite material combining the carbon fiber board and the EVA glue board, and is widely applied to the new energy automobile industry. However, in the prior art, because of structural design limitation, the connection mode of the support frame and the plate body is single, and a high-efficiency transmission path is lacked, so that the overall structural strength is insufficient, deformation and even fracture are easy to occur when bearing a large load, meanwhile, the material stacking mode is not optimized, the overall weight is increased by redundant materials, the light weight requirement is difficult to meet, in addition, the stress is concentrated at the connection node or weak part under the load effect, such as the corner of the plate body and the joint of the part, and the effective structure of the dispersed stress is lacked, so that the local premature damage is caused, the overall stress is unevenly distributed, and the bearing performance is further reduced. Disclosure of utility model The utility model aims to solve the problems of insufficient structural strength, large weight, uneven stress distribution and the like in the prior art, and the problems of difficulty in meeting the modern light weight and high bearing performance. In order to achieve the purpose, the lightweight EVA carbon fiber plywood comprises a supporting frame, a horizontal plate body and an arch plate body, wherein one end of the supporting frame is fixedly connected with one end of the horizontal plate body, a first connecting rod is fixedly arranged at the joint of the supporting frame and the horizontal plate body, one end of the arch plate body is fixedly connected at the joint of the supporting frame and the horizontal plate body, and the arch plate body is positioned above the supporting frame. Preferably, a reinforcing plate is fixedly connected between the arch plate body and the supporting frame, and the reinforcing plate is of a bending structure. Preferably, the top of the supporting frame is provided with a bending part which is fixedly connected with the arch plate body and the reinforcing plate. Preferably, a concave part is arranged at the joint of the reinforcing plate and the bending part, a second connecting rod is fixedly arranged at the joint of the reinforcing plate and the supporting frame, and the second connecting rod is fixedly connected with the first connecting rod. Preferably, rectangular through holes are formed at the junctions of the arch plate body, the reinforcing plate and the bending parts. Preferably, the corner of the horizontal plate body is provided with a positioning hole. Compared with the prior art, the utility model has the advantages and positive effects that: 1. According to the utility model, the EVA carbon fiber plywood is formed by the supporting frame, the horizontal plate body, the arch plate body and the reinforcing plate with the bending structure, when external force is born, the arch plate body disperses and transmits the force, the arch structure can effectively decompose the load in the vertical and horizontal directions, the reinforcing plate is connected with the arch plate body and the supporting frame, the bending structure increases the stress area and the structural stability, and all the components work cooperatively and resist the external force jointly. 2. In the utility model, the concave part at the joint of the reinforcing plate and the bending part can accommodate the stress generated by the deformation of the part, so that the stress concentration is prevented, the connection stability of the reinforcing plate and the supporting frame is further improved due to the existence of the second connecting rod, and the rectangular through holes formed by the arch plate body, the reinforcing plate and the bending part not only lighten the weight, but also do not influence the integral structural strength.
