Description

Golf swing analysis device capable of self-generation and charging {GOLF SWING ANALYSIS DEVICE CAPABLE OF SELF-GENERATION AND CHARGING}

The present invention relates to a golf swing analyzer capable of self-power generation and charging, and more specifically, is installed at a position as close as possible to the club head of a golf club and measures the trajectory size and trajectory according to each swing of an offset club and a recognition club. Based on the result of comparing the lie angles and lie angles, the type of club for recognition is automatically recognized. The integrated information can be automatically transmitted to the user terminal by analyzing the trajectory, trajectory, and shot quality and direction. It relates to a golf swing analyzer capable of self-power generation and charging that can be transmitted to a terminal (smart phone).

With the popularization of golf, the golf-related industry has grown rapidly, and accordingly, various golf swing exercisers have been released.

Conventional golf swing trainers are developed in the form of an independent swing tool in the shape of a golf club in most cases, rather than supporting golfers to practice using their own golf clubs. Such a conventional golf swing exerciser has a limitation in that it is difficult to fully expect the effect of the practice due to differences in grip, weight, and the like from the golf club owned by the golfer.

On the other hand, although golf swing practice is most effective in the field using one's own club, there are many golfers who visit screen golf driving ranges due to problems such as distance and cost. However, while there is an advantage of being able to practice with one's own golf club in a screen golf driving range, there is a limitation in that expensive sensor equipment for measuring a golfer's swing and displaying it on a large screen is required.

In addition, even when practicing at the screen golf driving range, in order to grasp accurate swing information such as flight distance according to the type of golf club, the settings of the computing equipment installed at the screen golf driving range must be individually changed according to the information of the golf club. There is discomfort.

To this end, conventionally, a technique for obtaining various sensor data according to the swing motion of the golf club by attaching it to the grip end of the golf club or the middle of the shaft, and automatically recognizing the type of golf club based on this has been developed.

However, in these conventional technologies, since the position where the sensor data is acquired is not close to the club head, but close to the grip where the user grips the club, a large error range is generated, resulting in club type recognition, trajectory recognition, swing speed recognition, etc. has a problem of low accuracy.

Hereinafter, a preferred embodiment is presented to aid understanding of the present invention. However, the following examples are only provided to more easily understand the present invention, and the content of the present invention is not limited by the examples.

1 is a diagram showing trajectory lengths and trajectory deviations according to club types, and the following table is a table summarizing shaft lengths and lie angles for each club.

In general, golf clubs differ in shaft length by at least 0.5 inch intervals for each type, and due to this shaft length difference, a lie angle between the ground and the club head also differs for each club.

Therefore, even for the same person, deviations occur in the swing trajectory length and trajectory of each club. As the shaft length becomes shorter, the trajectory length decreases and the trajectory changes more steeply.

Looking at the table above, it can be seen that shaft lengths and lie angles are differentiated according to club types such as woods, irons, and wedges, and in particular, even in the same club type, shaft lengths and lie angles are further subdivided according to club numbering.

Referring to FIG. 1(a), as the length of the shaft increases, a swing trajectory such as an outer large arc is drawn, and as the length of the shaft decreases, a swing trajectory such as an inner small arc is drawn.

In addition, as shown in FIG. 1 (b), since the distance between the golfer and the club head increases as the length of the shaft increases, the angle between the ground and the swing trajectory becomes gentler, and as the length of the shaft decreases, the distance between the golfer and the club head decreases. Because of this narrowing, the angle between the ground and the swing trajectory changes steeply.

That is, since the change in the length of the swing trajectory, the change in the trajectory, and the change in the lie angle according to the shaft length are numerical values that can be organized for each club, the present invention focuses on this point and based on the measurement data according to the club for a specific offset, I would like to explain the technology that can automatically recognize the type of club.

2 is a diagram schematically showing the shape of a golf swing analyzer 100 capable of self-power generation and charging according to an embodiment of the present invention, and FIG. 3 is a golf swing capable of self-power generation and charging shown in FIG. 2 It is a diagram showing the configuration of the analysis device 100 in more detail.

2 and 3, the golf swing analyzer 100 capable of self-power generation and charging according to an embodiment of the present invention largely includes a body part 110, a measuring part 120, a club recognition part 130, The analysis unit 140, the communication unit 150, the battery 160 for outputting the measurement results through the measurement unit 120 and the results through the club recognition unit 130 and the analysis unit 140 through the application program on the user terminal ) and a self-generation module 170 supplying power generated by self-generation to the battery 160 .

First, the body portion 110 may be installed to have a trajectory as close as possible to the trajectory of the club head by being positioned adjacent to a hosel formed below the shaft of the golf club, that is, directly above the hosel.

As the body portion 110 moves away from the club head, errors may occur in the measurement results such as the trajectory size, trajectory, and lie angle of the club head through the measuring unit 120, so the body portion 110 may be located near the hosel, which is as close to the club head as possible but does not affect the impact of the golf ball.

The body part 110 includes a compact and modular body body 111 including a measuring unit 120, a club recognition unit 130, an analysis unit 140, a communication unit 150, and a battery 160, It is configured to include a fixing clip 112 coupled to the body body 111 so that the body body 111 remains fixed without moving even in a swing motion in a state where the body body 111 is firmly fixed to the shaft.

One side of the body part body 111 and the fixing clip 112 may be fastened through a fitting or through a separate fastening means (not shown), and the outer diameter of the club shaft so that the club shaft can be interposed on the inside. A concave groove is formed in the inward direction to correspond to . As an anti-slip member (not shown) having frictional force is provided in the concave groove to prevent the body 111 from slipping from the shaft, the body 110 does not move and is firmly fixed even during the swinging motion of the club. can The non-slip member (not shown) may be made of silicone or rubber, and other materials may be used as long as there is frictional force.

The battery 160 provided on the body part body 111 serves to supply power to the measurement unit 120, the club recognition unit 130, the analysis unit 140, and the communication unit 150, and the battery 160 Can be charged by the power generated by the self-generation module 170 to be described later.

The measurement unit 120 measures the trajectory size, trajectory, and lie angle of the club head according to the swinging motion of the club inside the body part body 111, and the club recognition unit 130 and the analysis unit measure the measured values 140, and also serves to measure the direction of the space plane of the club head, which is the measurement result of the magnetic force sensor, and transmits the measured value to the analysis unit 140.

More specifically, the measuring unit 120 is operated by receiving power from the battery 160, and measures the instantaneous acceleration of the club head in the impact section according to the swing motion of the recognition club 3-axis acceleration sensor 121, Change amount of x-axis coordinate value and y-axis coordinate value on the coordinate plane system of the body body 111 with the shoulder position of the golfer as the rotation axis according to the swing motion of the offset club and the recognition club, respectively, and the club seated on the ground A 3-axis gyro sensor 122 measuring the lie angle of the head and a 3-axis magnetic force sensor measuring the angle formed by the space plane of the club head and a virtual straight line heading to the side of the golfer at the time of impact in the impact section ( 123) may be configured. This will be examined in more detail with reference to FIG. 4 .

FIG. 4 is a diagram illustrating characteristics of each sensor shown in FIG. 2 .

Referring to FIG. 4(a) , when a golfer swings a recognition club, the 3-axis acceleration sensor 121 serves to measure the instantaneous acceleration of the club head in an impact section according to a swing motion. In this case, when the swing is performed multiple times, each measured value of a plurality of instantaneous acceleration forces may be transmitted to the analyzer 140 . Based on the measured value transmitted to the analysis unit 140, the analysis unit 140, which will be described later, calculates the distance of the shot based on the average value of the instantaneous acceleration and the club type recognized by the club recognition unit 130.

Referring to FIG. 4(b), the 3-axis gyro sensor 122 begins with the club head seated on the ground (that is, the golfer grips the golf club and assumes the address posture), and performs a downswing from the backswing top posture. , impact, follow-through to the finish posture, by measuring the x-axis coordinate value and the y-axis coordinate value change amount on the coordinate plane system of the body body 111 for the entire motion process, and displaying this to the club recognition unit 130 in real time will be sent

In general, it takes approximately 3 to 4 seconds for a golfer to start from an address posture for a full swing and take a finish posture. The amount of change in the x-axis coordinate value and the amount of change in the y-axis coordinate value from to the top position after full swing are measured in real time and transmitted to the club recognition unit 130.

In addition, the 3-axis gyro sensor 122 measures the lie angle, which is an angle formed between the club head and the ground, in a state where the club head is seated on the ground (a state in which the golfer holds the golf club and assumes an address posture) to determine the position of the club. It is transmitted to the recognition unit 130.

Referring to Figure 4 (c), the three-axis magnetic force sensor 123, when the golfer swings while holding the club for recognition, the space plane of the club head passing through the impact section is a virtual straight line and a virtual straight line based on the golfer's side It serves to measure the angle formed.

In general, the space plane of the club head passing through the impact section can be largely divided into three types. First, as shown at the top of FIG. 4(c), when the angle formed by the space plane and a virtual straight line toward the side of the golfer is distorted to the left (ie, based on the direction of travel of the golf ball, the space plane is biased to the left and closed In this case), a pull ball appears, and in the case where the angle formed by the space plane and an imaginary straight line toward the golfer's side is intermediate (ie, when the golf ball's traveling direction and the space plane coincide), a straight ( straight) pitch appears, and if the angle formed by the space plane and an imaginary straight line toward the golfer's side is twisted to the right (that is, if the space plane is open to the right based on the direction of travel of the golf ball), push (push) The pitch appears.

Therefore, the 3-axis magnetic force sensor 123 measures the direction (open or closed angle) of the space plane and transmits it to the analysis unit 140, and the analysis unit 140 determines the quality and direction of the shot based on this. will be analyzed

Returning to FIGS. 2 and 3, the club recognition unit 130 measures the amount of change in the x-axis coordinate value for each club transmitted from the 3-axis gyro sensor 122, the amount of change in the y-axis coordinate value, and the lie angle After receiving, based on this, the trajectory size and trajectory of the club head for each club are calculated and stored in a data buffer. At this time, since the club for offset can be a criterion for automatically recognizing the club for recognition, the type of club for offset, the shaft length preset for the corresponding club, the lie angle, etc. are stored in advance.

More specifically, when the golfer swings the offset club for the first time in a state where the body portion 110 is installed in the offset club, the 3-axis gyro sensor 122 changes the x-axis coordinate value of the offset club. , The amount of change in the y-axis coordinate value and the lie angle are measured and transmitted to the club recognition unit 130, and then, the body part 110 installed in the offset club is separated from the offset club for recognition that requires type recognition After being installed on the club, when the club for recognition is swinging by the golfer, the 3-axis gyro sensor 122 measures the amount of change in the x-axis coordinate value, the amount of change in the y-axis coordinate value, and the lie angle for the club for recognition This is transmitted to the club recognition unit 130. At this time, each measurement value transmitted to the club recognition unit 130 is stored in real time in the data buffer.

The club recognition unit 130 calculates the trajectory size and trajectory of the club head of the offset club based on the amount of change in the x-axis coordinate value and the amount of change in the y-axis coordinate value for the offset club, and stores them in the data buffer. .

Since information on the club type, shaft length, and lie angle of the offset club is stored in advance, the club recognition unit 130 determines the trajectory size, trajectory, and lie angle of the club head of the offset club and the club of the club for recognition. After calculating the size of the trajectory of the head, the deviation between the trajectory and the lie angle, the type of club for recognition is recognized according to the degree of deviation.

For example, when the club for offset is set to a 7-iron, the shaft length of the 7-iron is 37 inches and the lie angle corresponds to 61 degrees. At this time, when the golfer swings the offset club for the first time, the 3-axis gyro sensor 122 measures the amount of change in the x-axis coordinate value, the amount of change in the y-axis coordinate value and the lie angle of the club head of the 7-iron, It is transmitted to the recognition unit 130.

Next, when the body part 110 is separated from the number 7 iron and installed on the club for recognition, and the golfer swings the club for recognition, the 3-axis gyro sensor 122 has an x-axis relative to the club head of the club for recognition. The amount of change in the coordinate value, the amount of change in the y-axis coordinate value, and the lie angle are measured and transmitted to the club recognition unit 130 .

The club recognition unit 130 calculates the difference between the trajectory size, trajectory, and lie angle of the 7-iron relative to the club head of the recognition club, and then automatically recognizes the club type corresponding to the deviation. .

The analysis unit 140 serves to analyze the flight distance according to the swing motion of the club for recognition, the quality and direction of the shot, based on the measurement result of the club for recognition measured by the measurement unit 130 .

More specifically, the analysis unit 140 is based on the average value of a plurality of instantaneous accelerations transmitted from the three-axis acceleration sensor 121 and the club type of the club for recognition automatically recognized by the club recognition unit 130, The flight distance according to the swing of the club for recognition is calculated and stored in the data buffer.

Since the instantaneous acceleration in the impact section is already stored in the data buffer through the 3-axis acceleration sensor 121 and the club type of the club for recognition is recognized through the club recognition unit 130, the analysis unit 140 Based on this, the distance of the club for recognition can be calculated. Even if the body part 110 is installed in another club for recognition, the instantaneous acceleration of the corresponding club for recognition and recognition of the club type must be preceded by the 3-axis acceleration sensor 121 and the 3-axis gyro sensor 122. Therefore, the analyzer 140 can automatically calculate the flight distance according to the swing of the club for recognition.

In addition, the analysis unit 140 calculates the trajectory size and trajectory of the club head for recognition previously calculated through the club recognition unit 130 and the impact point of the impact section transmitted from the 3-axis magnetic force sensor 123. Based on the direction the space plane faces, the pitch and direction of the shot according to the swing of the club for recognition are analyzed and stored in the data buffer.

The three-axis magnetic force sensor 123 can measure the angle formed by the space plane of the club head passing through the impact section with a virtual straight line based on the golfer's side when the golfer swings while holding the club for recognition, Since the trajectory size and the trajectory of the club head for recognition have already been calculated through the club recognition unit 130 and stored in the data buffer, the analysis unit 140 calculates the golf ball according to the swing of the club for recognition based on this. You can analyze pitches (pull, straight push) and their direction. The analyzed result is stored in the data buffer.

The communication unit 150 stores the measurement values for the offset clubs stored in the data buffer, the measurement values for the recognition clubs, and the trajectory size of each of the offset clubs and the recognition clubs calculated by the club recognition unit 130 based on the measurement values and the recognition clubs. By transmitting information on the trajectory, automatically recognized club type, and information on the distance analyzed through the analysis unit 140, the quality of the shot, and the direction of the shot to the user terminal (eg, smartphone), the user terminal It is output through a dedicated application running on the top so that the user can easily check the type of club that was swung next to the offset club, as well as the flight distance, shot quality, direction, etc., so that it can be confirmed immediately.

That is, when swinging with the golf swing analyzer 100 capable of power generation and charging by the viewer attached to the offset club only for the first time, the trajectory size, trajectory, and lie angle of the club head relative to the offset club After that, the trajectory size and trajectory of the club head for the corresponding club are automatically calculated by attaching the golf swing analyzer 100, which can be generated and charged by the viewer, to another club and swinging once. The club type according to the deviation of the trajectory size, trajectory and lie angle can be automatically recognized and automatically output to the user's smartphone. In addition, it is possible to automatically analyze the flying distance according to the swing of the recognition club, the quality of the shot, and the direction, organize them by club, and provide and output them to the user's smart phone.

At this time, the communication unit 150 may be paired with the user terminal through any one or more of Bluetooth communication or Wi-Fi communication with the user terminal (smartphone), and after the first pairing, when the power is turned on (on) operation automatically pairing takes place.

The self-powered module 170 is provided to be inserted into the shaft of the club, and when the club is swinging by the golfer, the self-powered power is self-generated as the self-powered battery is generated by repeatedly moving inside the enamel coil in which the magnetic material provided inside is wound multiple times. It serves to supply 160. This will be examined in more detail with reference to FIGS. 5 and 6 .

5 is a diagram showing the self-powered module 170 shown in FIG. 2 in more detail.

Referring to FIG. 5 , the self-power generation module 170 largely includes a hollow tube 171, an enamel coil 172, a diode rectifier circuit 173, and a magnetic body 174.

First, the hollow tube 171 is formed inside the shaft of the club smaller than the inner diameter of the shaft, and has a hollow inside and a cylindrical shape with both ends blocked. The hollow tube 171 may be insulated with an insulator material (eg, plastic or resin material).

On the outside of the hollow tube 171, an enamel coil 172 is wound multiple times along the length of the hollow tube 171, and on the inside of the hollow tube 171, a cylindrical shape formed corresponding to the inner diameter of the hollow tube 171 The magnetic body 174 of is located. Both ends of the enamel coil 172 are connected to the diode rectifier circuit 173, and the diode rectifier circuit 173 is connected to the battery 160 again.

FIG. 5(b) is a cross-sectional view of the self-power generation module 170 shown in FIG. 5(a). Referring to FIG. 5 (b), when the golfer swings, the magnetic body 174 repeatedly moves in a straight line in the vertical direction inside the hollow tube 171 due to gravity, and in this process, the enamel coil 172 and the magnetic body The power generated between 174 is applied to the battery 160 through the diode rectifier circuit 173. Meanwhile, a neodymium magnet having strong magnetic force may be applied to the magnetic body 174 .

Next, the process of automatically recognizing the type of club using the self-generating and charging golf swing analyzer 100 described above, and calculating the distance and analyzing the ball quality and direction accordingly will be reviewed in order.

FIG. 6 shows the process of automatically recognizing the type of golf club through the golf swing analyzer 100 capable of self-powering and charging shown in FIG. it is a drawing

Referring to FIG. 6, first, the body part 110 is installed at a position adjacent to the hosel formed on the lower side of the shaft of the offset club (S601), and as the golfer swings the offset club once, the measuring unit 120 for offset After measuring the amount of change in the x-axis coordinate value and the change in the y-axis coordinate value of the club head according to the swing of the club and the lie angle (S602), the measured values are transmitted to the club recognition unit 130, and the club recognition unit In (130), the measurement value of the offset club is stored in the data buffer, and at the same time, the trajectory size and trajectory according to the amount of change in the x-axis coordinate value and the amount of change in the y-axis coordinate value of the offset club are calculated, stored in the data buffer, and offset The setting of the dragon club is completed (S603).

In step S602, as the golfer swings the offset club once, the measurement unit 120, the club recognition unit 130, the analysis unit 140, and the communication unit 150 are affected by the self-powered module 170. The minimum required power will be produced. Also, in step S602, if the measured value is not accurate in this step or an error occurs in the measurement process, the measured value is acquired again through re-measurement.

Next, after the body part 110 is separated from the club for offset, it is installed in a position adjacent to the hosel formed below the shaft of the club for recognition that requires recognition (S604), and measured as the golfer swings the club for recognition once. In the unit 120, after measuring the amount of change in the x-axis coordinate value and the change in the y-axis coordinate value of the club head according to the swing of the club for recognition, and the lie angle (S605), the club recognition unit 130 converts the measured values to , and the club recognition unit 130 stores the measured value of the club for recognition in the data buffer, and at the same time, the trajectory size and trajectory according to the amount of change in the x-axis coordinate value and the amount of change in the y-axis coordinate value of the club for recognition Clubs for recognition based on the calculated and stored in the data buffer, and the deviation between the measured value for each club stored in the data buffer and the trajectory size, trajectory, and lie angle for each club head calculated by the club recognition unit 130 After automatically recognizing the type of (S606), the communication unit 150 transmits information on the result of recognizing the type of club for recognition accordingly to the user terminal (smart phone), so that the corresponding information is output through the user terminal The user can check this (S607).

When step S607 is completed, the analyzer 140 determines the flight distance according to the swing of the club for recognition based on the average value of the instantaneous acceleration transmitted from the 3-axis acceleration sensor and the type of club for recognition automatically recognized by the club recognition unit. It is calculated and stored in the data buffer (S608).

In addition, the analysis unit 140 calculates the trajectory size and trajectory of the club head for recognition calculated through the club recognition unit 130 and the space plane at the time of hitting the impact section transmitted from the 3-axis magnetic force sensor 123 Based on the heading direction (angle), the pitch (pull, straight, push, hook tendency, slice tendency, etc.) according to the swing of the recognition club and direction are analyzed and stored in the data buffer (S609).

Through steps S608 and S609, it is checked whether there is an error in the analysis data stored in the data buffer, and if there is no error in the analysis data, the communication unit 150 transmits the data stored in the data buffer to the user terminal (smartphone), so that the user terminal Corresponding information is output through , so that the user can check it, and if there is an error, it returns to step S605 to newly acquire measured values for the swing of the club for recognition (S610).

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention described in the claims below. You will understand that you can.
