Description

Ball serving bar for improving golf swing sound and speed by using aerodynamic principle

Technical Field

The present invention relates to a golf club head, and more particularly, to a driving club which improves the sound and speed of a golf swing using aerodynamic principles.

Background

In the golf game, when a user serves a golf ball, the swing speed of the golf club is increased, so that the golf ball achieves a longer distance, which is a key project developed by the current golf serving club. In order to achieve the above objectives of increasing the swing speed and achieving a longer distance, it is an important factor to develop a shape and structure design of an aerodynamic driver head.

The present golf teeing club comprises a shaft and a club head connected to the bottom end of the shaft, wherein the club head comprises a hollow club head body and a neck connected to one side of the front end of the club head body, and the shaft neck is connected to the shaft. The hollow club head body comprises a shell and a batting panel arranged on the front side of the shell, and the shell is a streamline type body forming an arc shape.

The conventional golf club can reduce air resistance by using the streamlined club head body when a ball is hit. However, in terms of aerodynamics, when the air flows backward with the striking face of the head of the golf club head facing the striking face during the striking of the golf club by the user holding the golf club, the air flows respectively through the shell crown and the shell sole of the head body and along the curved sidewall surfaces on both sides of the head, and there are problems that air resistance is large due to the viscosity between the air flow and the curved sidewall, and it is difficult for the user to obtain pleasant sound during the striking.

In addition, in the conventional golf club field, in order to reduce the air resistance of the club head during movement, a plurality of front through holes with smaller apertures are formed in the striking face plate at the front end of the club head, and a rear through hole with larger aperture is formed at the rear end of the casing of the club head. However, in the above-mentioned design of the club head, because the striking faceplate at the front end of the club head is provided with a plurality of front through holes, when the striking faceplate impacts a golf ball, the striking faceplate is liable to have an adverse effect on the striking, and the airflow enters the larger space inside the club head from the front through holes with smaller apertures in the striking faceplate at the front end of the club head and diffuses, and then is pushed by the larger space inside the club head to be discharged from the rear through holes at the rear end of the casing, so the airflow is liable to generate air resistance inside the club head.

In the prior art of golf clubs, some golf clubs have a plurality of airflow ducts extending from the front striking face of the club head to the rear end of the housing, which improve the problem of air resistance of the airflow to the interior of the club head due to the airflow from the club head through the front through hole with a smaller aperture in the front striking face of the club head into the larger space of the club head for diffusion and then from the rear through hole at the rear end of the housing through the larger space of the club head. However, in the above-described club head structure having the airflow duct, a plurality of through holes are formed in the ball striking face plate at the front end of the club head, and when the ball striking face plate collides with a golf ball, the impact tends to be adversely affected.

In addition, the club head with a plurality of front through holes on the front striking plate and a rear through hole on the rear end of the shell, or the club head with an airflow duct extending from the front striking plate to the rear end of the shell, are designed to improve the air resistance acting on the front striking plate of the club head, but the structure of the two club heads and the existing service club head still cannot provide a specific and effective solution for the problem that the air resistance is generated by the airflow passing through the viscosity of the arc-shaped side walls on the two sides of the club head during the movement of the club head, and the striking plate is provided with small apertures to pass through, so that the club head is not strong enough and is easy to break, and the sound generated during striking the ball has unpleasant wind cutting sound.
