Description

Technical Field

[0001] The present application relates to the field of water sports equipment, and in particular to a power-assisted hydrofoil surfboard. Background Art

[0002] At present, the hydrofoil surfboard market on the market mainly presents two mainstream products: non-powered surfboards and electric surfboards. However, these two types have some technical and usage limitations, which bring a series of challenges to different types of surfers.

[0003] First of all, non-powered surfboards are generally considered to be the first choice for advanced surfing enthusiasts or professional athletes. This type of surfboard requires surfers to have a high level of skills and strong physical fitness, because without external assistance, surfers need to rely on their own strength to drive the board forward. This highly technical and high-intensity physical requirement makes non-powered surfboards difficult to popularize. For ordinary users or beginners, the learning curve is steep and they may face the problem of physical exhaustion.

[0004] On the other hand, although electric surfboards provide convenient electric assistance, they also have some problems. First, electric surfboards are usually equipped with large-capacity batteries, which increases the weight of the board and makes it inconvenient to carry and operate. Secondly, the battery life and endurance of electric surfboards are also limiting factors. The long charging time and limited range will affect the user's time and experience in water activities.

[0005] In addition, advanced surfers usually like to use light and compact surfboards, but such light boards are easy to sink completely in the sea water, especially when the waves are large, the surfboards are often submerged by the waves. More seriously, the conductivity of seawater and the influence of waves on the remote control signal make the remote control signal unstable, or even completely lost, making it impossible for surfers to effectively control the surfboard, increasing the uncertainty and risk of surfing at sea.

[0006] In summary, there are a series of technical and usage challenges in the current hydrofoil surfboard market, which hinder the further development and popularization of the project. In order to solve these problems, it is necessary to develop a new type of hydrofoil surfboard that integrates an advanced electric power assist system, while taking into account lightness and stable remote control signals to meet the needs of different types of surfers and promote the development of hydrofoil surfing.
