Description
本發明是有關於一種擊球用具,且特別是有關於一種高爾夫推桿。The invention relates to a batting implement, and in particular to a golf putter.
隨著科技的迅速進步發展,物質文化、生活品質不斷提升,運動休閒活動蔚為風潮。原本被視為高級貴族專屬的高爾夫球運動,亦隨著運動休閒風潮而更趨普及。參與高爾夫球運動者遍及各個年齡層,不分男女都有不少熱愛者,且近年來參與高爾夫球運動的人數急遽增加。With the rapid development of science and technology, the material culture and quality of life have been continuously improved, and sports and leisure activities have become a trend. Originally regarded as exclusive golf for senior nobles, it has become more popular with the trend of sports and leisure. There are people of all ages who participate in golf. There are many lovers regardless of gender, and the number of people participating in golf has increased dramatically in recent years.
近年來,高爾夫推桿生產廠商不斷引進新材料與新技術以提升高爾夫推桿的品質。然而,高爾夫球的擊球表現除了與高爾夫推桿的品質有關,主要是與擊球者的揮桿動作有關。因此,若能準確地對擊球者的揮桿動作進行動態感測以作為修正揮桿動作的依據,將可大幅提升高爾夫球運動者的擊球表現。In recent years, golf putter manufacturers have continuously introduced new materials and technologies to improve the quality of golf putters. However, in addition to the quality of the golf putter, the performance of the golf ball is mainly related to the swing of the hitter. Therefore, if the swing motion of the hitter can be accurately sensed as the basis for correcting the swing motion, the hit performance of the golf player can be greatly improved.
本發明提供一種高爾夫推桿,可準確地對擊球者的揮桿動作進行動態感測。The invention provides a golf putter, which can accurately sense the dynamic motion of a golfer's swing.
本發明的具有感測器的高爾夫推桿,包括一桿身及一桿頭。桿頭連接於桿身且包括一桿頭主體及一感測器,其中桿頭主體的重心在高爾夫推桿進行揮桿時偏移至一偏移位置。感測器配置於桿頭主體上,感測器的質心偏離於桿頭主體的偏移位置。The golf putter with a sensor of the present invention includes a shaft and a club head. The club head is connected to the shaft and includes a club head body and a sensor, wherein the center of gravity of the club head body is shifted to an offset position when the golf putter swings. The sensor is disposed on the head body, and the center of mass of the sensor deviates from the offset position of the head body.
在本發明的一實施例中,在高爾夫推桿進行揮桿時,感測器的重心偏移至偏移位置而重合於桿頭主體的重心。In an embodiment of the invention, when the golf putter swings, the center of gravity of the sensor is shifted to the offset position and coincides with the center of gravity of the head body.
在本發明的一實施例中,上述的桿頭主體具有一擊球瞄準線,桿頭主體的偏移位置對位於擊球瞄準線,感測器的質心偏離於桿頭主體的擊球瞄準線。In an embodiment of the invention, the above-mentioned head body has a line of sight, the offset position of the head body is located at the line of sight, and the center of mass of the sensor deviates from the line of sight of the head body line.
在本發明的一實施例中,在高爾夫推桿進行揮桿時,感測器的重心偏移至擊球瞄準線而重合於桿頭主體的重心。In an embodiment of the present invention, when the golf putter swings, the center of gravity of the sensor is shifted to the line of sight of the ball and coincides with the center of gravity of the head body.
在本發明的一實施例中,上述的擊球瞄準線形成於桿頭主體的一表面上,一參考平面垂直於桿頭主體的表面,參考平面與桿頭主體的表面的交界線重合於擊球瞄準線,感測器的質心不位於參考平面上。In an embodiment of the present invention, the above-mentioned line of sight is formed on a surface of the head body, a reference plane is perpendicular to the surface of the head body, and the boundary between the reference plane and the surface of the head body coincides with the shot The aiming line of the ball, the centroid of the sensor is not on the reference plane.
在本發明的一實施例中,上述的桿身的一握持部與感測器的質心位於參考平面的同一側。In an embodiment of the invention, a grip portion of the shaft and the center of mass of the sensor are located on the same side of the reference plane.
在本發明的一實施例中,上述的感測器為動態感測器。In an embodiment of the invention, the above-mentioned sensor is a dynamic sensor.
在本發明的一實施例中,上述的感測器可拆卸地配置於桿頭主體。In an embodiment of the invention, the sensor described above is detachably arranged on the head body.
在本發明的一實施例中,上述的感測器具有一訊號傳送單元,且適於藉由訊號傳送單元將所感測到動態資訊傳送至一外部裝置。In an embodiment of the invention, the above-mentioned sensor has a signal transmission unit, and is suitable for transmitting the sensed dynamic information to an external device through the signal transmission unit.
基於上述,本發明在高爾夫推桿的桿頭主體上配置了感測器,用以在使用者揮動高爾夫推桿時感測桿頭主體的位移軌跡、加速度及速度等動態資訊。使用者能夠依據多次累積揮桿的這些動態資訊來調整自身的揮桿動作,以提升擊球表現。進一步而言,由於在揮桿過程中,桿頭是高爾夫推桿整體中迴轉半徑最大的部分而具有最大的單位時間位移量,因此配置於桿頭主體的感測器能夠在單位時間內獲取高解析度的動態資訊,使其具有良好的感測準確度。另一方面,由於在桿頭上配置了感測器會使桿頭與感測器整體的移動重心在揮桿角度及移動變化過程中與擊球瞄準線產生不同的向心加速度,故原有的揮桿軌跡會因為增加了感測器的重量與感測器重心安裝位置因素而產生角度偏移。為了避免因感測器的重心位置安裝不正確而使桿頭整體的重心非預期地偏離進而使原有的揮桿軌跡無法正確對應於桿頭主體上的擊球瞄準線,本發明將感測器的質心配置調整為偏離於桿頭主體的偏移位置(即桿頭主體的重心於揮桿時所偏移至的位置,亦可稱為桿頭主體於揮桿時的移動重心的所在位置),如此可使感測器的移動重心在揮桿過程中往桿頭主體的移動重心偏移或是使揮桿者以剛好吻合於擊球瞄準線的角度與方向進行揮桿,以將桿頭整體的移動重心維持於對應於擊球瞄準線的移動軌跡上,使感測器能夠在其不影響桿頭移動重心的情況下重現原有的揮桿軌跡以獲取準確的感測結果。Based on the above, the present invention configures a sensor on the head body of the golf putter for sensing dynamic information such as displacement trajectory, acceleration and speed of the head body when the user swings the golf putter. The user can adjust his swing according to the dynamic information of multiple accumulated swings to improve the hitting performance. Furthermore, since the head is the part with the largest radius of gyration in the entire golf putter and has the largest amount of displacement per unit time during the swing, the sensor arranged on the head body can obtain high The dynamic information of resolution makes it have good sensing accuracy. On the other hand, because the sensor is placed on the head, the center of gravity of the head and the sensor will have a different centripetal acceleration from the line of sight during the swing angle and movement change. Therefore, the original The swing trajectory will have an angular offset due to the increased weight of the sensor and the installation position of the center of gravity of the sensor. In order to avoid that the center of gravity of the entire head is unexpectedly deviated due to the incorrect installation of the center of gravity of the sensor and the original swing trajectory cannot correctly correspond to the line of sight on the head body, the present invention will sense The center of mass configuration of the instrument is adjusted to deviate from the offset position of the head body (that is, the position to which the center of gravity of the head body is offset when swinging, can also be referred to as the location of the center of gravity of the head body during swing Position), so that the center of gravity of the sensor can be shifted to the center of gravity of the head body during the swing or the swinger can swing at an angle and direction that is just in line with the line of sight of the shot, so that The overall center of gravity of the club head is maintained on the movement trajectory corresponding to the line of sight of the ball, so that the sensor can reproduce the original swing trajectory without affecting the center of gravity of the club head to obtain accurate sensing results .
為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.
圖1是本發明一實施例的高爾夫推桿的立體圖。請參考圖1,本實施例的高爾夫推桿100包括一桿身110及一桿頭120。桿頭120連接於桿身110且包括一桿頭主體122及一感測器124,桿頭主體122具有一擊球瞄準線122a。當使用者揮動高爾夫推桿100擊球時,可以將擊球瞄準線122a對準高爾夫球的球心,以準確地進行擊球。當使用者揮動高爾夫推桿100時,由於桿頭主體122的不同位置的質點會因其與揮桿的迴轉中心的距離不同而有不同的向心加速度(離迴轉中心越遠,向心加速度越大),而移動重心的位置與其各質點的加速度有關,故桿頭主體122的移動重心會因揮桿動作而沿遠離揮桿者的方向D偏移。需說明的是,前述及後述移動重心指的是除了相關於重力加速度亦相關於物體運動時所產生之其他加速度的廣義重心,或可稱之為慣性中心。其中,在桿頭主體122擊中高爾夫球之瞬間,桿頭主體122的移動重心偏移至特定位置(後述內容稱之為偏移位置)。可將擊球瞄準線122a設置為鄰近或位於所述特定位置,使擊球點對應於桿頭主體122的移動重心,從而使用者可準確地擊球。FIG. 1 is a perspective view of a golf putter according to an embodiment of the present invention. Please refer to FIG. 1. The
本實施例的感測器124例如是重力感測器(G-sensor)、陀螺儀(Gyro Meter)或其他適當種類的動態感測器。感測器124配置於桿頭主體122上,用以在使用者揮動高爾夫推桿100時感測桿頭主體122的位移軌跡、加速度、速度、重心位置等動態資訊。使用者能夠依據多次揮桿的這些動態資訊來調整自身的揮桿動作,以提升擊球表現。進一步而言,由於在揮桿過程中,桿頭120是高爾夫推桿100整體中迴轉半徑最大的部分而具有最大的單位時間位移量,因此配置於桿頭主體122的感測器124能夠在單位時間內獲取高解析度的動態資訊,使其具有良好的感測準確度。The
圖2是圖1的高爾夫推桿的局部放大圖。圖3是圖2的桿頭的俯視圖。請參考圖2及圖3,在本實施例中,擊球瞄準線122a形成於桿頭主體122的一表面122b上,一參考平面P(空間中的虛擬平面)垂直於桿頭主體122的表面122b,參考平面P與桿頭主體122的表面122b的交界線重合於擊球瞄準線122a,而感測器124的質心C(標示於圖3)不位於參考平面P上。並且,桿身110的一握持部112(繪示於圖1)與感測器124的質心C位於參考平面P的同一側。亦即,感測器124的質心C往桿身110的握持部112的方向偏離於桿頭主體122的偏移位置(即桿頭主體122的重心於揮桿時所偏移至的位置,亦可稱為桿頭主體122於揮桿時的移動重心的所在位置)且偏離於擊球瞄準線122a。在本實施例中,所述偏移位置例如對位於擊球瞄準線122a所在位置,然在其他實施例中,所述偏移位置可鄰近但不對位於擊球瞄準線122a所在位置,本發明不對此加以限制。FIG. 2 is a partial enlarged view of the golf putter of FIG. 1. 3 is a plan view of the head of FIG. 2. 2 and 3, in this embodiment, the line of
在揮桿過程中,由於感測器124的不同位置的質點會因其與揮桿的迴轉中心的距離不同而有不同的向心加速度(離迴轉中心越遠,向心加速度越大),而移動重心的位置與其各質點的加速度有關,故感測器124的移動重心亦會因揮桿動作而沿遠離揮桿者的方向D偏移。所述移動重心偏移現象為依據物理學之重心的定義可推知,於此不詳細贅述。為了避免因感測器124的移動重心偏移而使桿頭120整體的移動重心非預期地偏離,本實施例如上述般將感測器120的質心C配置為往握持部112的方向偏離於所述偏移位置及擊球瞄準線122a,如此可使感測器124的移動重心在揮桿過程中往所述偏移位置偏移或是剛好偏移至所述偏移位置(如擊球瞄準線122a所在位置)而重合於桿頭主體122的重心,以將桿頭120整體的移動重心維持為鄰近或位於對應於所述偏移位置的位置,使感測器124能夠在其不影響桿頭120移動重心的情況下進行準確的動態感測。During the swing, the particles at different positions of the
圖1至圖3所示感測器124與擊球瞄準線122a的相對位置關係僅為舉例,本發明不以此為限。在其他實施例中,感測器124與擊球瞄準線122a可為其他適當的相對位置關係而使感測器124偏離於擊球瞄準線122a。此外,圖1至圖3所示高爾夫推桿100例如是右手桿(其揮桿方向為由揮桿者的右往左),然本發明不以此為限,在其他實施例中,其可為左手桿(其揮桿方向為由揮桿者的左往右)。The relative positional relationship between the
本實施例的感測器124例如是不可拆卸地固定於桿頭主體122。以此配置方式而言,高爾夫推桿100例如是練習用高爾夫推桿,使用者可利用設有感測器124的高爾夫推桿100進行練習並依據感測器124感測到的動態資訊來調整自身的揮桿動作,以提升正式比賽時使用正式高爾夫推桿的擊球表現。所述練習用推桿的重心分配(即高爾夫推桿100)可與所述正式高爾夫推桿的重心分配完全相同,使所述動態資訊能夠符合所述正式高爾夫推桿所進行的擊球。在其他實施例中,感測器124亦可為可拆卸地配置於桿頭主體122。以此配置方式而言,使用者可利用裝設有感測器124的高爾夫推桿100進行練習並依據感測器124感測到的動態資訊來調整自身的揮桿動作,並利用卸除了感測器124的高爾夫推桿100進行正式比賽。The
圖4是圖1的感測器傳送訊號至外部裝置的示意圖。在本實施例中,感測器124可具有一訊號傳送單元124a,且適於以藍芽傳輸技術或其他適當的無線傳輸技術,藉由訊號傳送單元124a將所感測到動態資訊S傳送至一外部裝置50,讓使用者能夠透過外部裝置50的顯示介面即時觀看動態資訊S。外部裝置50例如是使用者的手機、平板電腦或筆記型電腦等可攜式電子裝置,本發明不對此加以限制。FIG. 4 is a schematic diagram of the sensor of FIG. 1 transmitting signals to an external device. In this embodiment, the
綜上所述,本發明在高爾夫推桿的桿頭主體上配置了感測器,用以在使用者揮動高爾夫推桿時感測桿頭主體的位移軌跡、加速度及速度等動態資訊。使用者能夠依據多次累積揮桿的這些動態資訊來調整自身的揮桿動作,以提升擊球表現。進一步而言,由於在揮桿過程中,桿頭是高爾夫推桿整體中迴轉半徑最大的部分而具有最大的單位時間位移量,因此配置於桿頭主體的感測器能夠在單位時間內獲取高解析度的動態資訊,使其具有良好的感測準確度。另一方面,由於在桿頭上配置了感測器會使桿頭與感測器整體的移動重心在揮桿角度及移動變化過程中與擊球瞄準線產生不同的向心加速度,故原有的揮桿軌跡會因為增加了感測器的重量與感測器重心安裝位置因素而產生角度偏移。為了避免因感測器的重心位置安裝不正確而使桿頭整體的重心非預期地偏離進而使原有的揮桿軌跡無法正確對應於桿頭主體上的擊球瞄準線,本發明將感測器的質心配置調整為偏離於桿頭主體的偏移位置(即桿頭主體的重心於揮桿時所偏移至的位置,亦可稱為桿頭主體於揮桿時的移動重心的所在位置),如此可使感測器的移動重心在揮桿過程中往桿頭主體的移動重心偏移或是使揮桿者以剛好吻合於擊球瞄準線的角度與方向進行揮桿,以將桿頭整體的移動重心維持於對應於擊球瞄準線的移動軌跡上,使感測器能夠在其不影響桿頭移動重心的情況下重現原有的揮桿軌跡以獲取準確的感測結果。此外,感測器可依需求被設計為可拆卸或不可拆卸地配置於桿頭主體,以提升其泛用性。In summary, the present invention is equipped with a sensor on the head body of the golf putter for sensing dynamic information such as the displacement trajectory, acceleration and speed of the head body when the user swings the golf putter. The user can adjust his swing according to the dynamic information of multiple accumulated swings to improve the hitting performance.
