Description

Technical Field

[0001] The present invention relates to a smart golf ball and a golf swing ball quality information providing system using the same, which obtains putting ball quality information including the hitting point, speed, rotation amount, slip amount, trajectory, movement distance, and separation angle of the golf ball during putting and provides it through a user terminal, not only maximizing the efficiency of putting practice but also being able to more finely correct the user's golf swing posture, particularly the golf putting posture.

Background Art

[0002] Generally, putting in golf means the action of hitting a golf ball with a putter to put the golf ball into the hole cup on the green. The golfer aligns the head of the putter with the golf ball while gripping the grip of the putter for putting, then sets the direction in which the golf ball will roll considering the slope angle of the green, the direction of the hole cup, etc., and then hits the golf ball with the head so that the golf ball enters the hole provided on the green.

[0003] However, many amateur golfers cannot put accurately, resulting in the phenomenon of losing scores due to putting, and since the number of strokes can also be reduced by putting, it is regarded as even more important than driving.

[0004] For these reasons, a considerable amount of effort in golf practice is devoted to putting practice, and various auxiliary mechanisms have been proposed to support putting practice more efficiently.

[0005] / As an example, Patent Document 1: Korean Registered Patent No. 10-1644502 describes a golf ball characterized by comprising: a sensor module located in the center of the golf ball, comprising a gyroscope sensor, an accelerometer sensor, a power supply, a transmitting chip that receives signals from the gyroscope sensor and the accelerometer sensor and transmits them to a smartphone, and an electronic circuit; a cushioning material made of silicone material surrounding the sensor module; a capsule made of carbon fiber reinforced plastic surrounding the cushioning material; a core made of soft carbonized cork surrounding the capsule; a mantle made of a composite material of long fiber reinforced thermo-fired resin containing carbon fibers surrounding the core; a cover made of soft urethane surrounding the mantle; and a wire extending outward from the center and connected to the transmitting chip to smoothly transmit signals from the transmitting chip located in the center of the golf ball to a smartphone located outside the golf ball, and an antenna installed on the underside of the cover and connected to the wire.

[0006] However, according to the aforementioned prior art documents, the antenna is configured to be inserted into a cover corresponding to the outer casing of a golf ball, which presents a problem as it is extremely vulnerable to external impacts.

[0007] Furthermore, according to the aforementioned prior art documents, since the cushioning material and capsule, and the capsule and core are constructed using a simple adhesive method, when an impact exceeding a certain force is applied, the adhesive force decreases, and a separation space is created between each component making up the golf ball. As a result, the direction of impact of the golf ball is determined by the separation space formed inside the golf ball when it is struck, regardless of the golfer's swing posture, which means that it is not possible to provide reliable data on the direction and force of impact of the golf ball.

[0008] Here, the applicant has filed and registered a smart golf ball trajectory information provision system, such as Patent Document 2: Registered Korean Patent No. 10-2685033, which generates and provides information on the movement trajectory of a struck golf ball to a user terminal, thereby improving the efficiency of putting practice. However, even in this system, since multiple pressure sensors are formed only on certain surfaces, there is a problem in that if the golf ball is not accurately struck on the part where the pressure sensor is located when it is struck, it is difficult to provide precise data on the movement trajectory of the struck golf ball.

[0024] The embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0025] As shown in the figure, the smart golf ball of the present invention comprises a control member 400 connected to a ball quality information provision system 500 and a network to collect golf ball movement information including the angular velocity, acceleration, and direction of movement of the golf ball; a protective cover 100 in which the control member 400 is installed to prevent damage or breakage caused by the impact generated when the golf ball is struck; an impact absorbing member 200 configured to surround the outer surface of the protective cover 100 and to absorb impact transmitted from the outside of the golf ball; and an outer shell 300 configured to surround the impact absorbing member 200 and formed in the same shape as the outer shape of the golf ball.

[0036] Furthermore, the cover fixing groove 142 formed in the first protective cover 102 and the cover fixing pin 144 formed in the second protective cover 104 are configured with connecting ribs 148 having cable through holes in their centers through which power cables and the like pass, so that the connecting housing 420 is electrically connected to the charging coil 410, which will be described later.

[0037] Furthermore, a battery support rib 146 is provided in the cover fixing groove 142 formed in the second protective cover 104. This rib extends to one side adjacent to the battery 450, ensuring that both outer surfaces of the battery 450 are in close contact with the battery 450, thereby supporting the battery 450 so that it is stably fixed to the mounting portion 130.

[0038] Here, the mounting portion 130 is formed with a battery fixing portion 134 that is spaced apart from the lower part of the board fixing groove 132 and supports the battery 450 so that it is mounted and fixed.

[0039] Furthermore, the mounting portion 130 includes a coil mounting portion 136 configured to be spaced a predetermined distance apart from the upper part of the board fixing groove 132, particularly the upper part of the connecting rib 148, and which supports the charging coil 410 of the control member 400 so as to be fixed in place, and a coil mounting support portion 138 which is formed to extend from the inner circumferential surface of the first and second protective covers 102 and 104 toward the center, and which is in close contact with the lower surface of the charging coil 410.

[0040] Furthermore, the mounting portion 130 has a housing fixing portion 150 formed on the lower surface of the connecting rib 148, which supports the control member 400 so as to be coupled to and fixed to the upper surface of the connecting housing 420.

[0041] The protective cover 100 of the present invention, configured in this manner, is made of polyamide material, but is not limited thereto.

[0042] The shock-absorbing member 200 is made of an elastic rubber material and is formed in a spherical shape to surround the protective cover 100, playing a role in minimizing the transmission of external impacts from the golf ball to the protective cover 100.

[0043] Such shock-absorbing member 200 can be made of a composite rubber material.

[0044] Here, the composite rubber may be a rubber in which niodium polybutadiene (NdBR), zinc oxide (ZnO), a rubber crosslinking agent, an organic peroxide, and a compound are blended in a certain weight ratio.

[0045] In the present invention, the viscosity of niodium polybutadiene is limited to 60, but the invention is not limited thereto.

[0046] Furthermore, rubber crosslinking agents are used to enhance elasticity, strength, and durability during rubber processing, and in this invention, ZDA and Zn-st are used.

[0047] Alternatively, Trigonox 29 / 40 from Trigonox Corporation may be used as the organic peroxide.

[0048] The compound may also be Compound Mooney (FMB).

[0049] The outer shell 300 is configured to surround the outer surface of the shock-absorbing member 200, and is made of a material in which ionomer and titanium oxide are blended in a certain weight ratio, and is configured to have the outer shape of a normal golf ball.

[0050] The control unit 400 collects golf ball movement information, including angular velocity, acceleration, and direction of movement, when the smart golf ball of the present invention is struck, and transmits the collected movement information to the ball quality information provision system 500, which not only maximizes the efficiency of putting practice but also allows for more detailed correction of the user's golf swing posture, particularly the golf putting posture. The control unit 400 comprises a charging coil 410, a connection housing 420, an antenna 430, a control board 440, and a battery 450.

[0051] The charging coil 410 is configured to be charged wirelessly and is configured to be electrically connected to the connecting housing 420 via a power cable.

[0052] The connecting housing 420 is configured to connect the charging coil 410 and the battery 450, and to transmit electrical energy supplied via the charging coil 410 to the battery 450 for charging.

[0053] The antenna 430 is connected to the control board 440, and the control board 440 transmits golf ball movement information to the ball quality information provision system 500, thus including a standard wireless communication module.

[0054] The control board 440 includes a first control board 442 which comprises a sensor unit 460 that collects golf ball movement information, and a second control board 444 which is connected to the first control board 442 and transmits the movement information collected by the sensor unit 460 to the ball quality information provision system 500.

[0055] The first control board 442 consists of a sensor unit 460 which includes a gyro sensor 462 that measures the angular velocity of the golf ball with respect to its rotation angle per hour when the smart golf ball of the present invention is struck, an acceleration sensor 464 that measures the acceleration of the golf ball, and a geomagnetic sensor 466 that collects information regarding the direction and orientation of the golf ball's movement.

[0056] Here, the sensor unit 460 consists of a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis geomagnetic sensor, and transmits the measured information to the second control board 444.

[0057] The second control board 444 includes a communication module 470 that transmits golf ball movement information measured by the sensor unit 460 to the ball quality information provision system 500 under the control of the control unit 480, and a control unit 480 that controls whether or not the sensor unit 460 is driven, receives golf ball movement information transmitted from the sensor unit 460, and provides the received movement information to the ball quality information provision system 500 via the communication module 470.

[0058] Here, the control unit 480 checks whether a wireless communication connection is established with the ball quality information provision system 500. If wireless communication is established, it sends a drive confirmation request signal for the sensor unit 460 via the communication module 470. If a drive approval signal is received, it controls the sensor unit 460 to enable it to drive.

[0059] Here, the control unit 480 can request information on the movement of the golf ball after the sensor unit 460 has been driven. If this information on the movement of the golf ball is above a certain value, it can request the ball quality information provision system 500 to verify whether or not there is an error in the sensor unit 460.

[0060] On the other hand, the control board 440 can be further configured with a board connector 446 that connects the first and second control boards 442 and 444 to it and performs data transmission and reception for these first and second control boards 442 and 444.

[0061] At the same time, the battery 450 supplies power to the first and second control boards 442 and 444.

[0062] On the other hand, the golf swing ball quality information provision system 500 using the smart golf ball of the present invention receives movement information of the smart golf ball from the control member 400, analyzes the received movement information of the golf ball to generate putting ball quality information, and transmits the generated putting ball quality information to the user terminal 600, as shown in Figure 5.

[0063] Such a ball quality information provision system 500 is configured to be able to communicate wirelessly via a communication module 470 to a control unit 480 configured on the second control board 444 of the control member 400, and is connected to a user terminal 600 via a network to generate and provide the user's putting ball quality information.

[0064] This ball quality information provision system 500 receives golf ball movement information from the control unit 480, generates putting ball quality information for the smart golf ball, and transmits it to the user terminal 600.

[0065] Here, putting ball quality information includes the point of impact, speed, spin, slip, trajectory, distance traveled, and separation angle of the golf ball.

[0066] Furthermore, the ball quality information provision system 500 stores the generated putting ball quality information, and when putting ball quality information is generated for the same user terminal 600, it generates comparative putting ball quality information by comparing it with the previous putting ball quality information. When the comparative putting ball quality information is accumulated more than a certain number of times, it can analyze this information to generate a change value for the smart golf ball and transmit it to the user terminal 600.

[0067] Such a ball quality information provision system 500 can send a request signal transmitted from the control unit 480 to the user terminal 600 to request an approval signal corresponding to the request signal.

[0068] The user terminal 600 is connected to the ball quality information provision system 500 via a network, and the putting ball quality information generated when the smart golf ball is struck is transmitted from the ball quality information provision system 500 and displayed.

[0069] Such a user terminal 600 can classify the generated putting ball quality information into categories and display each category individually.

[0070] Furthermore, the user terminal 600 is configured to display each piece of information included in the putting ball quality information transmitted from the ball quality information provision system 500 in a graph. When displayed in graph format, it is configured to overlay the accumulated putting ball quality information, allowing users to check the amount of change in the putting ball quality information of the smart golf ball.

[0071] On the other hand, the communication module 470 and the network connected to the communication module 470 described in the present invention refer to a connection structure that enables information exchange between each node, such as multiple terminals and servers. Examples of such communication modules 470 and networks include, but are not limited to, RF, 3GPP® (3rd Generation Partnership Project) networks, LTE (Long Term Evolution) networks, 5GPP (5th Generation Partnership Project) networks, WiMAX (World Interoperability for Microwave Access) networks, the Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth® (Bluetooth) networks, NFC networks, satellite broadcasting networks, analog broadcasting networks, and DMB (Digital Multimedia Broadcasting) networks.
