The optical pointer 132 is, for example, a laser light source and is adapted to emit a pointing beam L perpendicular or approximately perpendicular to the ball striking surface of the club head 120. The pointing beam L is adapted to change with the orientation angle of the ball striking surface of the club head 120. And aim at the target direction of a target position P (for example, a flagpole on a green). The sensor 134 is, for example, a gravity sensor (G-sensor), a gyroscope (Gyro Meter) or other appropriate types of dynamic sensors, and is suitable for sensing the orientation angle of the club head 120.

As shown in FIG. 2, the sensing pointing device 130 of this embodiment further includes a judging unit 136. The determining unit 136, the optical pointer 132, and the sensor 134 can be integrated into a sensing module. The determining unit 136 includes, for example, a determining circuit and is electrically connected to the sensor 134. When the pointing beam L is aligned with the target direction of the target position P, the club head 120 has an orientation angle (hereinafter also referred to as the first orientation angle). When the club head 120 hits the golf ball, the club head 120 has another orientation angle. The orientation angle (hereinafter also referred to as the second orientation angle), the determining unit 136 is used to determine the difference between the two orientation angles, so that the user can correct his swing motion accordingly. This is explained in more detail below.

3A to 3C illustrate the functioning mode of the sensing pointing device of FIG. 1, where the Z axis is, for example, an axis parallel to the direction of gravity, and the X axis, Y axis, and Z axis are perpendicular to each other. The user can use the optical pointer 132 of the sensing pointing device 130 (shown in FIG. 2) to emit a pointing beam L as shown in FIG. 3A, and let the pointing beam L change with the orientation angle of the club head 120 on the XY plane And as shown in FIG. 3B, aim at the target direction where the target position P is located. Wherein, the pointing beam L is, for example, perpendicular to a ball striking surface 120a of the club head 120. At this time, the sensor 134 (shown in FIG. 2) of the sensing pointing device 130 can sense the current orientation angle of the club head 120 and its striking surface 120a on the XY plane, and adjust the orientation angle (that is, the first Orientation angle) as the reference value. Then, the optical pointer L is closed as shown in FIG. 3C. Then, when the user swings and hits the ball, the sensor 134 of the sensing pointing device 130 can sense the orientation angle of the club head 120 and its hitting surface 120a on the XY plane at the moment of hitting the ball (ie, the second orientation angle). By comparing the orientation angle with the reference value by the determining unit 136, it can be known whether the user's shot angle is deviated and the degree of deviation of the shot angle can be known, so that the user can perform swing actions accordingly The amendment.

In this embodiment, when the sensor 134 senses at least one of a predetermined displacement and a predetermined angle change of the club head 120 and determines that the user enters the aiming action, the optical pointer 132 is triggered to turn on, and when When the sensor 134 senses at least one of another predetermined displacement and another predetermined angle change of the club head 120, or senses that the club head 120 generates the other predetermined displacement and the other predetermined angle change When at least one of them lasts for a predetermined time, the optical pointer 132 is turned off. For example, when the user wants to aim at the target direction where the target position P is located, he can first visually adjust the orientation of the club head 120 left and right to make it align with the target direction where the target position P is located. At this time, the sensor 134 senses It is measured that the left and right tilt angle of the club head 120 changes within a predetermined angle range (such as 0~5 degrees or 0~10 degrees) and then stands still for a predetermined length of time (such as 3~5 seconds), and then the user can as shown in Figure 3A It is shown that the club head 120 is slightly tilted downward. At this time, the sensor 134 senses that the downward tilt angle of the club head 120 is greater than a predetermined value (such as 5 degrees or 10 degrees) and generates a sensing signal accordingly. The measurement signal is directly or indirectly transmitted to the optical pointer 132, and the optical pointer 132 is turned on to emit a pointing beam L. When the user finishes the aiming and wants to close the optical pointer 132, he can make the club head 120 back up as shown in FIG. 3C.

The sensing signal is directly or indirectly transmitted to the optical pointer 132, and the optical pointer 132 is turned off accordingly. The opening and closing mechanism of the optical pointer 132 can be customized according to requirements, and the present invention does not limit this.

Furthermore, in order to prevent the sensor 134 from erroneously determining that the optical pointer 132 needs to be turned on due to the downward tilt of the club head 120 during the user’s swing, the determination mechanism can be designed to be that when the sensor 130 senses When the moving speed of the head 120 is greater than a predetermined value, even if the head 120 is tilted downward, the optical pointer 132 will continue to close without being triggered to open. The predetermined value of the moving speed of the club head 120 can be determined according to requirements, and the present invention does not limit its actual value. In addition, in other embodiments, other appropriate methods can be used to trigger the opening and closing of the optical pointer 132, which is not limited in the present invention.

If the determining unit 136 determines that the first orientation angle is slightly different from the second orientation angle, the determining unit 136 may transmit a second determination signal to the light indicator 138, and the light indicator 138 displays the second light signal accordingly. If the judging unit 136 judges that the first orientation angle has a large deviation from the second orientation angle, the judging unit 136 can transmit a third judgment signal to the light indicator 138, and the light indicator 138 displays the third light signal accordingly. The criteria for judging the negligible small deviations, small deviations, and large deviations can be formulated according to requirements, and the present invention does not limit this. In addition, the difference between the first light signal, the second light signal, and the third light signal can be the color of the light signal, the number of times the light signal flashes, or can be combined with sound effects to make it easier for the user to distinguish the judgment result of the judgment unit 136 The invention does not impose restrictions on this.
