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.
The present application relates to the field of water sports, and in particular, to a surfboard and a water sports device.
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.
The present application resolves one of the technical problems in the related art at least to a certain extent. To this end, an objective of embodiments of the present application is to provide a surfboard, which uses a rigid support assembly to replace a carbon fiber layer to serve as an anti-bending framework of the surfboard, such that the production process for the surfboard can be simplified, and the production efficiency can be improved.
A second objective of the embodiments of the present application is to provide a water sports device.
The technical solution adopted by the embodiments of the present application is as follows.
In a first aspect, there is provided a surfboard. The surfboard includes a board body, and a rigid support assembly embedded in the board body.
Further, the support assembly includes an annular support, and a reinforcing member connected on the support.
Furthermore, the support includes a first arm section, a second arm section, a third arm section, and a fourth arm section. The first and second arm sections extend in a length direction of the surfboard and are arranged oppositely, and both the first and second arm sections are arc-shaped arm sections; both ends of the third arm section are connected to a head end of the first arm section and a head end of the second arm section respectively, and both ends of the fourth arm section are connected to a tail end of the first arm section and a tail end of the second arm section.
Furthermore, at least one of the third and the fourth arm sections is an arc-shaped arm section, or at least one of the third and the fourth arm sections is a linear arm section.
Further, the support includes a plurality of arm sections connected in sequence, and both ends of the reinforcing member are connected to two oppositely arranged arm sections, respectively.
Further, the support includes a plurality of arm sections connected in sequence, and both ends of the reinforcing member are connected to two adjacent arm sections, respectively.
Further, a plurality of reinforcing members arranged in parallel are included, and there are gaps between the reinforcing members.
Further, the support assembly further includes a handle connected onto the support and protruding from the board body.
Further, the support assembly is made of a metal material, and the board body is a foam layer covering an outside of the support assembly.
In a second aspect, there is provided a water sports device. The water sports device includes a driving assembly and a power assembly, and further includes the above-mentioned surfboard. Both the driving assembly and the power assembly are fixed on the support assembly.
The embodiments of the present application use a rigid support assembly to replace a carbon fiber layer to serve as an anti-bending framework of the surfboard, such that the production process for the surfboard can be simplified, and the production efficiency can be improved.

Referring to
The reinforcing member 220 is board-shaped and extends in the width direction, and both ends of the reinforcing member 220 are respectively connected to the first arm section 211 and the second arm section 212, so as to achieve the purpose of further reinforcing strength.
Both the first arm section 211 and the second arm section 212 in the present embodiment are arc-shaped arm sections, and project toward the outside as illustrated in
The present embodiment is an improved embodiment of the first embodiment, and differs from the first embodiment in that: the present embodiment is provided with a plurality of parallel reinforcing members 220, and there are gaps between the reinforcing members 220, so as to be able to further reinforce strength and to avoid excessive increase in self-weight at the same time.
The present embodiment is an alternative embodiment of the first embodiment. Referring to
The present embodiment is an alternative embodiment of the first embodiment. Referring to
