[Technical field to which the invention belongs]

 The present invention relates to a kind of recess structure for guiding a golf club driver head. In particular, a guideway is set up on a golf club driver head, so that the route before the golf club driver hits the ball first penetrates the upper and lower airflows, balances the airflow pressures at the top and bottom of the golf club driver, and achieves accurate shots. The present invention relates to a flow-guiding recess structure of a golf club driver head that effectively improves the performance.

[0002]

[Prior art]

 As FIG. 1 shows, a conventional golf club driver connects a driver head on the distal end of a shaft. The player grasps the grip at the top end of the shaft and swings the shaft to strike a ball. However, in the conventional driver head design, the curved surface length of the top curved surface and the bottom slope is different, so when the shaft is swung downward from above, the driver head has a curved surface on the top curved surface. According to Bernoulli's law, air follows a relatively long streamline. Since the streamline of the top curved surface is longer, its airflow velocity is relatively high and relatively smaller than the pressure of the bottom slope (see P1 <P2 in FIG. 2). Thus, when the driver head is swung down in a parabola, the driver head will not move along the parabolic route under the pressure of the different airflows at which the apex curved upper end area and the bottom slope lower end area occur. Perform stable movement. The batter focuses on the ball several times in advance, but the driver head deviates from the route and cannot meet the center of gravity of the ball because the driver head generates an unstable floating phenomenon due to the air pressure difference. . As a result, the result of the shot by the driver is always biased to the right or left and is not stable, and the success rate is low.

[0003]

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks of the known structure, an object of the present invention is to provide a guiding recess structure of a golf club driver head. It is because the airflow recesses that penetrate the curved top surface and the bottom slope are installed on the driver head, so that different air pressures located in the top curved surface top area and the bottom slope bottom area during the swing process. The air flows in equilibrium and there is no air pressure difference, and the driver head moves stably and accurately on the planned parabolic route. In this manner, the unstable floating phenomenon caused by the known pressure difference of the driver head can be completely eliminated.

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides the following golf club driver head. The diversion recess structure includes an upper diversion port and a lower diversion port. The upper flow inlet is provided on a curved surface at a vertex close to a side surface of the driver head arc. In addition, the upper outlet forms a cutout on the top end of the arc side surface. The lower outlet is located on a bottom slope adjacent to the driver head arc side surface. In addition, the lower outlet forms a cutout on the bottom end of the arc side surface. The upper and lower outlets are continuous with each other to form a continuous wall. The continuous wall forms an opening on a circular arc side surface between the cutout of the upper inlet and the cutout of the lower outlet. The opening, the continuous wall surface, the upper channel, and the lower channel are connected to each other to form a channel. Utilizing the guide flow path, in the course of a swing, the airflows located at the top curved surface upper end area and the bottom sloped lower end area conduct with each other, and the pressures at the top curved surface and the bottom slope are balanced, The air pressure difference during the swing process disappears, and the vehicle moves on the planned parabolic route stably and accurately, and the ball path after the shot becomes accurate.

Both end sides of the flow guiding concave portion 30 are respectively continuous with the top surface curved surface 21 and the bottom inclined surface 22 of the driver head 20. Moreover, the opening 36 is located exactly on the arcuate side surface 24 of the driver head 20. Further, as shown in FIGS. 4, 5, and 6, the flow guide recess 30 includes an upper flow port 31 and a lower flow port 32. The upper flow inlet 31 is installed on the curved surface 21 at the vertex close to the arcuate side surface 24 of the driver head 20. In addition, the upper channel 31 forms a cutout 33 on the top end 241 of the arc side surface 24. The lower flow inlet 32 is installed on the bottom slope 22 adjacent to the arcuate side surface 24 of the driver head 20. In addition, the lower outlet 32 forms a cutout 34 on the bottom end 242 of the arc side surface 24.

The continuous wall surface 35 forms an opening 36 on the arcuate side surface 24 between the notch 33 of the upper channel 31 and the notch 34 of the lower channel 32. The opening 36, the continuous wall surface 35, the upper channel 31, and the lower channel 32 are mutually connected to form a channel 37.

[0007] Subsequently, as shown in FIG. 7, in the swinging process, when the airflow passes over the upper end area of the top curved surface 21 and the lower end area of the bottom slope 22, the air current flows on the top surface 21 and the bottom slope 22. , Airflow pressures P1 and P2 are generated, respectively. The P1 and P2 are guided by the curved surface of the apex curved surface 21 and the slope of the bottom slope 22, respectively. Enter into 37. As a result, the airflow pressures P1 and P2 in the upper end section of the top curved surface 21 and the lower end section of the bottom slope 22 are constantly conducted and balanced (P1 = P2). In this way, the driver head 20 does not cause a floating phenomenon due to a difference in airflow pressure over the entire swing route from the top to the bottom of the parabola, and thus does not deviate from the swing route. That is, the accuracy in the direction of the ball path after the shot can be effectively improved.
