AI Technical Summary
Existing marine steering wheels are prone to slipping due to seawater adhesion, lack anti-slip design, and the traditional design does not fit the palm well. Holding them for a long time can easily lead to hand fatigue and slippage, especially when sailing in turbulent conditions, the hand is prone to shifting back and forth.
A steering wheel body with a racetrack-shaped cross section was designed, featuring intersecting annular grooves and X-shaped patterns, combined with a micro-convex particle structure for rapid drainage and increased friction, adapting to different grip postures.
It effectively avoids the risk of slipping in seawater, improves the stability and comfort of holding, is suitable for long-term operation, and reduces hand fatigue and displacement.

Abstract
Claims
1. A marine steering wheel, characterized in that include: The steering wheel body (1) is circular in shape and has a racetrack-shaped cross section. The racetrack-shaped cross section consists of two parallel straight edges and two semicircular arcs of equal radius. The two semicircular arcs correspond to the front and rear walls of the steering wheel body (1) to form an arc-shaped cross section, and the two parallel straight edges correspond to the inner and outer walls of the steering wheel body (1) to form a flat cross section. The connecting rod (2) is fixedly connected at one end to the inner wall of the steering wheel body (1); The center disc (3) is located at the center of the steering wheel body (1) and is fixedly connected to the steering wheel body (1) through the connecting rod (2); Two sets of annular grooves (4) are intersecting and surrounding the outer wall of the steering wheel body (1).
2. A marine steering wheel according to claim 1, characterised in that The outer radius of the steering wheel body (1) is 150~180mm.
3. The marine steering wheel of claim 1, wherein, The depth of the annular groove (4) is 2~4mm, the width is 2~3mm, and the maximum groove spacing between the two annular grooves (4) is 4~6mm.
4. The marine steering wheel of claim 1, wherein, The annular groove (4) has a rounded transition of R0.5~R1mm at the opening and bottom.
5. The marine steering wheel of claim 1, wherein, The intersection angle of the two sets of annular grooves (4) is 8 to 15 degrees.
6. The marine steering wheel of claim 1, wherein, The inner wall of the steering wheel body (1) is provided with several sets of X-shaped patterns (5), and the ends of the X-shaped patterns (5) are gradually shallow and flat.
7. The marine steering wheel of claim 1, wherein, The front and rear walls of the steering wheel body (1) are provided with micro-protruding particles (6), which are set to fit the arc of the palm.
8. The marine steering wheel of claim 1, wherein, The steering wheel body (1) is a hollow structure.
