Description

Golf club head and striking panel thereof

Technical Field

The invention relates to a golf club head and a hitting panel thereof.

Background

Characteristic Time (CT) of a golf club head refers to a contact time of a striking plate of the golf club head with a golf ball at the time of striking the ball, and a CT value is related to a flight distance of the golf ball after striking the ball. According to the American Association of Professional Golfers' specifications, the CT value of the striking plate must be no more than (less than or equal to) 257 microseconds (musec). The CT value is in positive correlation with the elastic coefficient of the batting panel, and can be used for judging the elastic coefficient of the batting panel.

Since the CT values of different positions on the striking plate are not completely the same, when the contact position of the golf ball and the striking plate is different, the flight distance of the golf ball is different depending on the CT value (modulus of elasticity) of the contact position. In particular, the difference between the CT values at different positions on the striking plate of the prior art is large, and the difference between the maximum value and the minimum value of the CT values at different positions can reach more than 20 μ sec, that is, the difference between the rebound coefficients at different positions of the striking plate is large, that is, the rebound coefficients show a low consistency.

For the golf users, due to the instability of the hitting posture, power or other factors, it is difficult to accurately control the contact position of the hitting panel with the golf ball, and the rebound coefficients of different positions of the hitting panel show considerable variability, so that the hitting performance of the golf ball shows a rather unstable state.

The base plate is also provided with a central shaft, an upper half plate body and a lower half plate body, the upper half plate body and the lower half plate body are connected with the central shaft, so that a first side surface and a second side surface are formed, the average thickness of the upper half plate body is larger than that of the lower half plate body, a second transition inclined surface is formed at the position, corresponding to the central shaft, of the first side surface, and the Y-shaped protruding blocks are arranged on the upper half plate body and the lower half plate body in a spanning mode.

The positive progress effects of the invention are as follows:

in the striking face plate of the golf club head and the golf club head of the present invention, the consistency of the rebound coefficients of different positions of the striking face plate can be effectively improved by the Y-shaped projecting block which is arranged on the first side surface in a projecting manner and straddles the upper half plate body and the lower half plate body, the first transition slope formed between the Y-shaped top surface and the first side surface, and the second transition slope formed on the first side surface at a position corresponding to the central axis (the upper half plate body and the lower half plate body are connected to the central axis), thereby being beneficial to improving the overall striking performance of a golf user.
