Description

CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority to Chinese patent application No. 201910884876.X, filed to the China National Intellectual Property Administration on Sep. 19, 2019 and entitled “Surfboard and Water Sports Device”, the disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present application relates to the field of water sports, and in particular, to a surfboard and a water sports device.

BACKGROUND

With the development of science and technology, a water sports device such as an electric surfboard has gradually become popular. During use, a surfboard needs to withstand a reaction force from a water surface, so that the surfboard itself is required to have high strength to avoid bending during surfing, and meanwhile should not have excessive self-weight to facilitate being carried. Due to the above-mentioned factors, most of current surfboards adopt a foam material as a base material, and then a surface of the foam material is connected with a carbon fiber layer to reinforce strength. However, the addition of carbon fiber is very cumbersome, in which an artificial shaping is required, thereby causing low production efficiency. It is difficult to meet actual production needs.
