Description

混合材料高爾夫球桿頭 Mixed material golf club head

本發明係有關於具有混合材料構造的高爾夫球桿頭。 The present invention relates to a golf club head having a mixed material structure.

一般而言，高爾夫球桿頭的整體性能取決於多項重要物理參數(例如容積、質量等等)，而總質量即是高爾夫球桿頭最重要的物理參數。高爾夫球桿頭的總質量是總結構質量與總自由設置質量的總和。結構質量概指為使桿頭能夠耐受反覆撞擊所需結構彈性的材料質量。結構質量受設計所左右，因此設計人員在比質量分佈方面的掌控空間有限。反之，自由設置質量是可添加至桿頭設計而賦予球桿客製化性能及/或寬容度的一切額外質量(超過高爾夫球桿頭最低結構要求者)。此技藝中需要一種可以為所有金屬高爾夫球桿頭提供最大化自由設置重量以達成最大桿頭慣性矩(MOI)並將重心(CG)下移/後移的方式。 Generally speaking, the overall performance of a golf club head depends on a number of important physical parameters (such as volume, mass, etc.), and the total mass is the most important physical parameter of the golf club head. The total mass of the golf club head is the sum of the total structural mass and the total free setting mass. Structural quality generally refers to the material quality of the structural elasticity required for the club head to withstand repeated impacts. The quality of the structure is controlled by the design, so the designer has limited control space in terms of the specific mass distribution. On the contrary, the free setting quality is all the extra quality (that exceeds the minimum structural requirements of the golf club head) that can be added to the club head design to give the club customized performance and/or latitude. There is a need in this art to provide all metal golf club heads with a way to maximize the freedom to set the weight to achieve the maximum moment of inertia (MOI) and move the center of gravity (CG) down/back.

本發明提供一種高爾夫球桿頭，其係包含相互結合的混合材料後本體與金屬前本體，所述金屬前本體包含擊球面及周圍框架。混合材料後本體包含纖維加固式熱塑性複合材料彈性層、模製熱塑性結構層、金屬配重墊及固定在金屬配重墊內的金屬重物。混合材料後本體構造可大幅 減輕結構質量，有助於改善自由設置質量的分配，從而改善高爾夫球桿頭的MOI及CG。 The present invention provides a golf club head, which includes a mixed material rear body and a metal front body that are combined with each other, and the metal front body includes a ball striking surface and a surrounding frame. The mixed material body includes a fiber-reinforced thermoplastic composite elastic layer, a molded thermoplastic structural layer, a metal weight pad and a metal weight fixed in the metal weight pad. After mixing materials, the body structure can be greatly Reducing the structural quality helps to improve the distribution of free setting quality, thereby improving the MOI and CG of the golf club head.

在某些實施例中，高爾夫球桿頭100包含一金屬前本體104及一複合材料後本體108，其中該後本體包含一編織纖維加固式熱塑性彈性層148、一模製熱塑性結構層152及一金屬配重墊156。與完全以金屬製成的類似桿頭相較，使用編織纖維加固式熱塑性彈性層148與模製熱塑性結構層152的組合可減輕結構質量。 In some embodiments, the golf club head 100 includes a metal front body 104 and a composite rear body 108, wherein the rear body includes a woven fiber reinforced thermoplastic elastic layer 148, a molded thermoplastic structural layer 152, and a Metal weight pad 156. Compared with similar heads made entirely of metal, the use of the combination of the woven fiber reinforced thermoplastic elastic layer 148 and the molded thermoplastic structural layer 152 can reduce the structural quality.

使用彈性層148與結構層152來減輕結構重量的作法可用於減輕桿頭100整體重量(藉此加快桿頭速度及/或加長飛行距離)，或用於增加高爾夫球桿頭100上可允許的自由設置質量範圍。在一實施例中，因使用複合材料彈性層148與複合材料結構層152而獲得的額外的自由設置質量，可 透過金屬配重墊156的形式重新導入於桿頭100中。以輕量複合材料後本體108結合金屬配重墊156可使桿頭100將大部分質量放置在可盡量放大MOI及CG的位置，從而提高寬容度並加大擊球距離。 The use of the elastic layer 148 and the structural layer 152 to reduce the structural weight can be used to reduce the overall weight of the club head 100 (thereby speeding up the club head and/or lengthening the flight distance), or to increase the allowable weight of the golf club head 100 Freely set the quality range. In one embodiment, the additional free setting quality obtained by using the composite material elastic layer 148 and the composite material structure layer 152 can be It is re-introduced into the club head 100 in the form of a metal weight pad 156. Combining the lightweight composite material with the rear body 108 and the metal weight pad 156 enables the club head 100 to place most of its mass in a position where the MOI and CG can be enlarged as much as possible, thereby increasing latitude and increasing the hitting distance.

甲.擊球面A. Batting surface

參照圖5、6及9，高爾夫球桿頭100的前本體104包含一用於敲擊高爾夫球的擊球面120。擊球面120包含一中心點160、一高擊平面164及一中間平面168。中心點160與桿頭100的冠部112及底部116為等距，且與最靠近趾部128的面的邊緣及最靠近踵部124的擊球面120邊緣為等距。高擊平面164與桿頭100擊球面120的中心點160相切。高擊平面164與地面180交叉。 5, 6 and 9, the front body 104 of the golf club head 100 includes a ball striking surface 120 for striking a golf ball. The ball hitting surface 120 includes a center point 160, a high hitting plane 164 and a middle plane 168. The center point 160 is equidistant from the crown 112 and the sole 116 of the head 100, and is equidistant from the edge of the face closest to the toe 128 and the edge of the ball striking face 120 closest to the heel 124. The high hitting plane 164 is tangent to the center point 160 of the hitting surface 120 of the club head 100. The high-attack plane 164 crosses the ground 180.

桿頭100擊球面120的厚度是擊球面120與前本體104內表面170之間的距離。擊球面120的厚度在不同位置上各不相同，因此定義可變擊球面厚度(VFT)或可變厚度輪廓196。可變厚度輪廓196具有一中央區域192及一周邊區域188。在許多實施例中，可變厚度輪廓196的中央區域192為橢圓形、卵形或蛋形。中央區域192概呈橢圓形狀，且自是擊球面120靠 近底部116及踵部124的部分延伸到擊球面120靠近該趾部128及冠部112的部分。 The thickness of the ball striking surface 120 of the head 100 is the distance between the ball striking surface 120 and the inner surface 170 of the front body 104. The thickness of the ball striking surface 120 is different in different positions, so a variable ball striking surface thickness (VFT) or a variable thickness profile 196 is defined. The variable thickness profile 196 has a central area 192 and a peripheral area 188. In many embodiments, the central area 192 of the variable thickness profile 196 is elliptical, oval, or egg-shaped. The central area 192 has an elliptical shape, and it is close to the hitting surface 120. The portion near the bottom portion 116 and the heel portion 124 extends to the portion of the ball striking surface 120 near the toe portion 128 and the crown portion 112.

參照圖6，中央區域192延伸跨越或位於或接近擊球面120的中心點160，使得擊球面120中心點160位於中央區域192內。中央區域192包含擊球面120的最大厚度。在許多實施例中，中央區域192的厚度實質上維持一致。周邊區域188位於擊球面120外周140的周圍且包含擊球面120的最小厚度。在許多實施例中，周邊區域188的厚度實質上維持一致。擊球面120在中央區域192內的厚度大於擊球面120在周邊區域188內的厚度。過渡區域190位於中央區域192與周邊區域188之間。過渡區域190包括變化厚度，在中央區域192與周邊區域188之間產生過渡。 Referring to FIG. 6, the central area 192 extends across or is located at or close to the central point 160 of the ball striking surface 120 such that the central point 160 of the ball striking surface 120 is located within the central area 192. The central area 192 contains the maximum thickness of the ball striking surface 120. In many embodiments, the thickness of the central region 192 remains substantially uniform. The peripheral area 188 is located around the outer circumference 140 of the ball striking surface 120 and includes the minimum thickness of the ball striking surface 120. In many embodiments, the thickness of the peripheral region 188 remains substantially uniform. The thickness of the ball striking surface 120 in the central area 192 is greater than the thickness of the ball striking surface 120 in the peripheral area 188. The transition area 190 is located between the central area 192 and the peripheral area 188. The transition area 190 includes a varying thickness, creating a transition between the central area 192 and the peripheral area 188.

此外，擊球面120的長軸184概延伸於踵部124到趾部128方向。長軸184與中心點160相交，且與地面形成一角度β。在許多實施例中，長軸184反映中央區域192的橢圓形狀。 In addition, the major axis 184 of the ball striking surface 120 generally extends from the heel 124 to the toe 128 direction. The long axis 184 intersects the center point 160 and forms an angle β with the ground. In many embodiments, the major axis 184 reflects the elliptical shape of the central region 192.

長軸184與地面180形成的角度約為20度。例如，形成於中央區域192長軸與地面180之間的角度可為0至60度。在某些實施例中，形成於中央區域192長軸184與地面180之間的角度可為2至20、2至30、5至40、10至50或15至60度。在其他實施例中，長軸184與地面180之間的角度可為5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24、25、26、27、28、29、30、31、32、33、34、35、36、37、38、39、40、41、42、43、44、45、46、47、48、49、50、51、52、53、54、55、56、57、58、59或60度。中央區域192具有角度傾向可致使蛋形的縱長部分朝向擊球面120的趾部上方CT值高的部分延伸，藉此改善擊出的球速。 The angle formed by the long axis 184 and the ground 180 is approximately 20 degrees. For example, the angle formed between the long axis of the central area 192 and the ground 180 may be 0 to 60 degrees. In some embodiments, the angle formed between the long axis 184 of the central region 192 and the ground 180 may be 2 to 20, 2 to 30, 5 to 40, 10 to 50, or 15 to 60 degrees. In other embodiments, the angle between the long axis 184 and the ground 180 may be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59 or 60 degrees. The central area 192 has an angular tendency to cause the egg-shaped elongated portion to extend toward the portion above the toe portion of the ball striking surface 120 with a high CT value, thereby improving the speed of the ball.

橢圓或卵形或蛋形，連同可變厚度輪廓196中央區域192的角度，可使擊球面120的加厚區域位於CT本身較高的區域，且使擊球面120的減薄區域位於CT本身較低的區域。據此，擊球面上CT本身較高的區域會減少，且CT本身較低的區域會增加，致使整個擊球面120的CT常態化。在許多實施例中，可變厚度輪廓196使得特徵時間小於115微秒(μs)、小於110μs、小於105μs、小於100μs、小於95μs、小於90μs或小於85μs的。再者，在許多實施例中，可變厚度輪廓40使得平均特徵時間大於230μs、大於235μs或大於240μs。例如，在許多實施例中，面板20的平均CT可為230μs至240μs、235μs至240μs或240μs至245μs。 The ellipse or oval or egg shape, together with the angle of the central area 192 of the variable thickness profile 196, can make the thickened area of the ball striking surface 120 be located in the higher area of the CT itself, and the thinned area of the ball striking surface 120 can be located in the CT The lower area itself. Accordingly, the area with higher CT itself on the hitting surface will decrease, and the area with lower CT itself will increase, resulting in the normalization of CT on the entire hitting surface 120. In many embodiments, the variable thickness profile 196 is such that the characteristic time is less than 115 microseconds (μs), less than 110 μs, less than 105 μs, less than 100 μs, less than 95 μs, less than 90 μs, or less than 85 μs. Furthermore, in many embodiments, the variable thickness profile 40 is such that the average characteristic time is greater than 230 μs, greater than 235 μs, or greater than 240 μs. For example, in many embodiments, the average CT of the panel 20 may be 230 μs to 240 μs, 235 μs to 240 μs, or 240 μs to 245 μs.

再者，VFT的角度是設計將擊球面120的加厚區域放置在所需位置，因此相較於不具有上述可變厚度輪廓196的擊球面，擊球面120可減輕重量。額外自由設置重量可重新導入於桿頭的其他區域，以調整桿頭重心位置並增加桿頭慣性矩，從而改善桿頭性能。與不具可變厚度輪廓196的類似桿頭比較，圖示實施例中具有可變厚度輪廓196的桿頭100，如在此所述者，可省下2.1公克的重量。 Furthermore, the angle of the VFT is designed to place the thickened area of the ball striking surface 120 at a desired position. Therefore, compared to the ball striking surface without the aforementioned variable thickness profile 196, the ball striking surface 120 can reduce the weight. The additional freely set weight can be re-introduced to other areas of the head to adjust the position of the center of gravity of the head and increase the moment of inertia of the head, thereby improving the performance of the head. Compared with a similar head without a variable thickness profile 196, the head 100 with a variable thickness profile 196 in the illustrated embodiment, as described herein, can save 2.1 grams of weight.

When the front body 104 and the rear body 108 are combined, the outer surface 172, the crown member 204, and the sole member 208 of the front body 104 form the entire crown 112 and sole 116 of the golf club head 100. The bottom part 208 of the rear body 108 may further include a composite elastic layer 152, a composite structure layer 156 and a metal weight pad 212.

在本設計中，後本體108可包括模製熱塑性材料(例如射出成形熱塑性材料)與纖維加固式熱塑性複合材料的混合。如在此所用，模製熱塑性材料是仰賴聚合物本身來為最終組件提供結構及剛性。模製熱塑性材料則是透過例如射出成形等模製成形技術，使材料在加熱至超過聚合物熔點的溫度時呈現自由流動狀態。經混入填充材料的模製熱塑性材料稱為填料式熱塑性(FT)材料。填料式熱塑性材料在加熱/融化狀態下可自由流動。為促進流動特性，填充材料大致包括最大維度小於約25毫米，或更常見者 為小於約12毫米的分離微粒狀物質。例如，填充材料可包括最大維度為4毫米、5毫米、6毫米、7毫米、8毫米、9毫米或10毫米的分離微粒狀物質。適合用於本設計的填充材料可為例如玻璃珠或由碳、玻璃或芳香族聚醯胺聚合物所構成的非連續性加固纖維。 In this design, the rear body 108 may include a mixture of molded thermoplastic material (e.g., injection molded thermoplastic material) and fiber-reinforced thermoplastic composite material. As used herein, molded thermoplastics rely on the polymer itself to provide structure and rigidity to the final assembly. Molded thermoplastic materials use molding techniques such as injection molding to make the material present a free-flowing state when heated to a temperature above the melting point of the polymer. Molded thermoplastic materials mixed with filler materials are called filler-type thermoplastic (FT) materials. Filled thermoplastic materials can flow freely when heated/melted. To promote flow characteristics, the filling material generally includes the largest dimension less than about 25 mm, or more commonly It is a separated particulate matter smaller than about 12 mm. For example, the filling material may include separated particulate matter having a maximum dimension of 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. Suitable filler materials for this design can be, for example, glass beads or discontinuous reinforcing fibers composed of carbon, glass or aromatic polyamide polymers.

對比於模製及填料式熱塑性材料，纖維加固式複合材料(FRC)材料通常包括一或多層延伸跨越聚合物大部分面積的單向或多向纖維布料。與用在FT材料中的加固纖維不同，FRC中所用纖維的最大維度可能更大/更長，且具有足夠的大小及特性，使其可成為與聚合物分離的連續布料。當與熱塑性聚合物一起成形時，即使聚合物已經融化而呈流動狀時，其中所包含的連續纖維通常也不會流動。 In contrast to molded and filled thermoplastic materials, fiber-reinforced composite (FRC) materials typically include one or more layers of unidirectional or multidirectional fiber fabrics that extend across most of the polymer area. Unlike the reinforcing fibers used in FT materials, the maximum dimension of the fibers used in FRC may be larger/longer, and have sufficient size and characteristics to make it a continuous fabric separated from the polymer. When molded together with a thermoplastic polymer, the continuous fibers contained therein generally do not flow even when the polymer has melted and becomes fluid.

FRC材料的成形方式通常是先將纖維設置成所需排列，而後使纖維材料吸入足量而可使其產生剛性的聚合物材料。以此方式，FT材料的樹脂含量可大於約45%體積比或更佳的是大於約55%體積比，而FRC材料的樹脂含量宜小於約45%體積比，或更佳的是小於約35%體積比。傳統上FRC材料的聚合物基質是雙劑型熱固性環氧化物，但也可使用熱塑性聚合物來做為基質。在許多情況下，會在最終製造前預先製備FRC材料，而這種中間材料通常稱為預浸體。若使用熱固性聚合物，則預浸體是部分固化為中間型態，待預浸體形成為最終形狀時再進行最終固化。若使用熱塑性聚合物，則預浸體可包括冷卻的熱塑性基質，隨後再接受加熱並模製成最終形狀。此一技術可用來製造像是後本體108這樣複雜且輕量的幾何形狀，但不會犧牲強度。 The FRC material is usually formed by first arranging the fibers into the desired arrangement, and then sucking in sufficient amount of the fiber material to produce a rigid polymer material. In this way, the resin content of the FT material can be greater than about 45% by volume or more preferably greater than about 55% by volume, while the resin content of the FRC material is preferably less than about 45% by volume, or more preferably less than about 35. %Volume ratio. Traditionally, the polymer matrix of FRC materials is a two-component thermosetting epoxy, but thermoplastic polymers can also be used as the matrix. In many cases, FRC materials are prepared in advance before final manufacturing, and this intermediate material is often called a prepreg. If a thermosetting polymer is used, the prepreg is partially cured into an intermediate shape, and the final curing is performed after the prepreg is formed into the final shape. If a thermoplastic polymer is used, the prepreg may include a cooled thermoplastic matrix, which is then heated and molded into the final shape. This technique can be used to manufacture complex and lightweight geometric shapes like the rear body 108 without sacrificing strength.

甲.冠部件A. Crown parts

後本體108包含冠部件204。參照圖4及圖9，冠部件204包含一外表面206，因此當後本體108與前本體104接合時，冠部件204的外表面206與周圍框架136的外表面172形成高爾夫球桿頭100的整個冠部112。冠部件204外表面206概呈相對於地面180凹入的曲線形狀。當將冠部件整個放置於前本體104的凸緣174上時，冠部件204的曲線形狀使得後本體208可以無縫接合於前本體104。 The rear body 108 contains the crown member 204. 4 and 9, the crown member 204 includes an outer surface 206, so when the rear body 108 is engaged with the front body 104, the outer surface 206 of the crown member 204 and the outer surface 172 of the surrounding frame 136 form the golf club head 100 The entire crown 112. The outer surface 206 of the crown member 204 generally has a concave curved shape with respect to the ground 180. When the crown member is placed entirely on the flange 174 of the front body 104, the curvilinear shape of the crown member 204 allows the rear body 208 to be seamlessly joined to the front body 104.

在許多實施例中，冠部件204是由碳纖維織物構成，沒有任何複合材料夾層或單向複合材料夾層。在一實施例中，製作冠部件204的成形纖維加固式複合材料中可包含內嵌於聚合物基質中的編織玻璃或碳纖維加固層。在此種實施例中，聚合物基質較佳的是熱塑性材料例如聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺，例如PA6或PA66。在其他實施例中，冠部件204的材質可為其中嵌設有玻璃珠或不連續玻璃、碳或芳香族聚醯胺聚合物纖維填料的填料式熱塑性材料，其基本的熱塑性材料可為，例如，聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺。在其他實施例中，冠部件204可採用兼具填料式熱塑性材料及成形纖維加固式複合材料的混合材料構造。 In many embodiments, the crown member 204 is composed of carbon fiber fabric without any composite material interlayer or unidirectional composite material interlayer. In one embodiment, the shaped fiber-reinforced composite material used to make the crown member 204 may include a woven glass or carbon fiber reinforcement layer embedded in a polymer matrix. In such an embodiment, the polymer matrix is preferably a thermoplastic material such as polyphenylene sulfide (PPS), polyether ether ketone (PEEK) or polyamide, such as PA6 or PA66. In other embodiments, the material of the crown member 204 may be a filled thermoplastic material with glass beads or discontinuous glass, carbon or aromatic polyamide polymer fiber filler embedded therein, and the basic thermoplastic material may be, for example, , Polyphenylene sulfide (PPS), polyether ether ketone (PEEK) or polyamide. In other embodiments, the crown member 204 may be constructed of a mixed material that combines a filler-type thermoplastic material and a formed fiber-reinforced composite material.

乙.底部件B. Bottom part

後本體108包含底部件208。參照圖4及9，底部件208包含結構層156及彈性層152，提供輕量但堅固的高爾夫球桿頭100底部116。彈性層152與地面180相切，而結構層156是位於彈性層152頂部上，且在高爾夫球桿頭100的內部。 The rear body 108 includes a bottom part 208. 4 and 9, the bottom member 208 includes a structural layer 156 and an elastic layer 152 to provide a lightweight but strong bottom 116 of the golf club head 100. The elastic layer 152 is tangent to the ground 180, and the structural layer 156 is located on top of the elastic layer 152 and inside the golf club head 100.

在一實施例中，底部件208的混合材料構造兼具纖維加固式熱塑性複合材料彈性層152及模製熱塑性結構層156。在一較佳實施例中，模製熱塑性結構層156可使用填料式熱塑性材料形成，此填料式熱塑性材料是在例如聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺(例如PA6或PA66)等熱塑性材料中嵌入玻璃珠或不連續玻璃、碳或芳香族聚醯胺聚合物纖維填料而成。所述彈性層152可包含內嵌於熱塑性聚合物基質中的編織玻璃、碳纖維或芳香族聚醯胺聚合物纖維加固層，所述熱塑性聚合物基質包括，例如，聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺，例如PA6或PA66。在一特定實施例中，冠部件202及彈性層152可各包含內嵌於聚苯硫醚(PPS)中的編織碳纖維布料，且該結構層156可包含一填料式聚苯硫醚(PPS)聚合物。 In one embodiment, the mixed material structure of the bottom member 208 has both a fiber-reinforced thermoplastic composite elastic layer 152 and a molded thermoplastic structural layer 156. In a preferred embodiment, the molded thermoplastic structural layer 156 can be formed using a filler-type thermoplastic material, which is made of, for example, polyphenylene sulfide (PPS), polyether ether ketone (PEEK) or polyamide ( For example, thermoplastic materials such as PA6 or PA66) are embedded with glass beads or discontinuous glass, carbon or aromatic polyamide polymer fiber filler. The elastic layer 152 may include a reinforcement layer of woven glass, carbon fiber or aromatic polyamide polymer fiber embedded in a thermoplastic polymer matrix, the thermoplastic polymer matrix including, for example, polyphenylene sulfide (PPS), Polyetheretherketone (PEEK) or polyamide, such as PA6 or PA66. In a specific embodiment, the crown member 202 and the elastic layer 152 may each include a woven carbon fiber cloth embedded in polyphenylene sulfide (PPS), and the structural layer 156 may include a filled polyphenylene sulfide (PPS) polymer.

結構層156可大致包括一前部236及一定義底部件208外周的外周部240。桿頭100組裝完成時，前部236是結合於該金屬前本體104，且外周部240是結合於冠部件204。結構層156具有複數個位於外周之內的孔洞244，各自延伸通過結構層156的厚度。再者，結構層156可包括一或個多結構件248，其係自該前部236延伸於至少兩個上述孔洞244之間。此外，如下所述，結構層156可配置為包含一金屬配重墊212及金屬重物220。 The structural layer 156 may generally include a front portion 236 and an outer peripheral portion 240 defining the outer periphery of the bottom member 208. When the club head 100 is assembled, the front part 236 is coupled to the metal front body 104, and the outer peripheral part 240 is coupled to the crown member 204. The structural layer 156 has a plurality of holes 244 located inside the outer circumference, each extending through the thickness of the structural layer 156. Furthermore, the structure layer 156 may include one or more multi-structure members 248 extending from the front portion 236 between the at least two holes 244 described above. In addition, as described below, the structure layer 156 may be configured to include a metal weight pad 212 and a metal weight 220.

彈性層152可結合於該結構層156而直接抵頂或覆蓋前部236、外周部240及複數結構件248的至少一部分。藉此，從桿頭100外部來看，彈性層152可完全涵蓋各該複數孔洞244。同樣，彈性層244的內部可含有一或多個結構件248做為選擇性的加固結構，類似於加強肋或角板。 The elastic layer 152 can be combined with the structural layer 156 to directly abut or cover at least a part of the front part 236, the outer peripheral part 240 and the plurality of structural members 248. Therefore, from the outside of the club head 100, the elastic layer 152 can completely cover each of the plurality of holes 244. Similarly, the inside of the elastic layer 244 may contain one or more structural members 248 as selective reinforcement structures, similar to reinforcing ribs or gussets.

關於冠部件204及底部件208兩者的聚合物構造，所用的填料式熱塑性材料或纖維加固式熱塑性複合材料宜包含一或多種具有足夠材料 強度及/或強度/重量比特性而能耐受通常使用，同時有助於減輕設計重量的工程聚合物。具體而言，高爾夫球桿頭100的材料必須能夠有效耐受因擊球面120與高爾夫球之間撞擊而產生的應力，並且不會造成高爾夫球桿頭100總重實質增加。整體而言，較佳的聚合物應具有大於約60MPa(純聚合物)的降伏抗拉強度，且當含有填料時，其降伏抗拉強度大於約110MPa，或更佳的是大於約180MPa，又更佳的是大於約220MPa。在某些實施例中，適合的填料式熱塑性聚合物可具有約60MPa至約350MPa的降伏抗拉強度。在某些實施例中，這些聚合物在填料及非填料狀態下的密度可為約1.15至約2.02，且熔化溫度較佳的是大於約210ºC，或更佳的是大於約250ºC。 Regarding the polymer construction of both the crown part 204 and the bottom part 208, the filler-type thermoplastic material or fiber-reinforced thermoplastic composite material used should preferably contain one or more materials with sufficient An engineering polymer with strength and/or strength/weight ratio that can withstand normal use while helping to reduce the design weight. Specifically, the material of the golf club head 100 must be able to effectively withstand the stress generated by the impact between the ball striking face 120 and the golf ball, and not cause the total weight of the golf club head 100 to increase substantially. On the whole, the preferred polymer should have a yield tensile strength greater than about 60 MPa (pure polymer), and when it contains fillers, its yield tensile strength is greater than about 110 MPa, or more preferably greater than about 180 MPa, and More preferably, it is greater than about 220 MPa. In certain embodiments, a suitable filled thermoplastic polymer may have a yield tensile strength of about 60 MPa to about 350 MPa. In certain embodiments, the density of these polymers in the filled and unfilled state can be from about 1.15 to about 2.02, and the melting temperature is preferably greater than about 210°C, or more preferably greater than about 250°C.

丙.配重墊C. Weight pad

參照圖4及圖9-11，在許多實施例中，結構層156可包括一配重墊212。配重墊212包含一可用於容納金屬重物220的凹腔216。在某些實施例中，配重墊212概朝向桿頭100的最後端點設置，因此可整合及/或直接耦合於結構層156後部132。在某些實施例中，彈性層152可具有孔洞或開口252，以供配重墊212的一部分延伸通過其中。在某些實施例中，上述開口250與前本體104相隔一至少25毫米或至少30毫米或至少35毫米(沿桿頭外表面測量)的最小距離。如圖9所示，組裝完成時，配重墊212的外表面可與直接毗鄰的底部件208及/或彈性層152外表面齊平。以此方式，配重墊212的一部分可形成高爾夫球桿頭100外側底部116的一部分。此外，在某些實施例中，配重墊212的內表面可暴露於球桿頭的內部。配重墊212的作用是提供密集的向後質量以改善高爾夫球桿頭的整體MOI。由於複合材料後本體108 大幅減輕重量，因此自由設置質量可集中放置在配重墊212及重物220所在的區域。 4 and 9-11, in many embodiments, the structural layer 156 may include a weight pad 212. The weight pad 212 includes a cavity 216 that can be used to accommodate the metal weight 220. In some embodiments, the weight pad 212 is generally disposed toward the rear end of the club head 100, so it can be integrated and/or directly coupled to the rear 132 of the structural layer 156. In some embodiments, the elastic layer 152 may have holes or openings 252 for a portion of the weight pad 212 to extend therethrough. In some embodiments, the opening 250 is separated from the front body 104 by a minimum distance (measured along the outer surface of the club head) of at least 25 mm, or at least 30 mm, or at least 35 mm. As shown in FIG. 9, when the assembly is completed, the outer surface of the weight pad 212 may be flush with the outer surface of the immediately adjacent bottom member 208 and/or the elastic layer 152. In this way, a portion of the weight pad 212 may form a portion of the outer sole 116 of the golf club head 100. In addition, in certain embodiments, the inner surface of the weight pad 212 may be exposed to the inside of the club head. The function of the weight pad 212 is to provide dense rearward mass to improve the overall MOI of the golf club head. As the composite material rear body 108 The weight is greatly reduced, so the freely set mass can be concentrated in the area where the counterweight pad 212 and the weight 220 are located.

配重墊212可包含任何所需形狀，盡可能使最多質量放置在高爾夫球桿頭100後部132的外周。配重墊212形狀可為以下任一者：圓形、三角形、方形、矩形、梯形、五邊形、曲線、桃形或任何其他多邊形或具有至少一個彎弧表面的形狀。在一實施例中，配重墊212可概呈梯形。在另一實施例中，配重墊212可略呈矩形。此外，在另一實施例中，配重墊212可略呈圓形。又或者，在另一實施例中，配重墊212可略呈三角形。 The weight pad 212 may comprise any desired shape so as to place the most mass on the outer periphery of the rear portion 132 of the golf club head 100 as much as possible. The shape of the weight pad 212 may be any of the following: a circle, a triangle, a square, a rectangle, a trapezoid, a pentagon, a curve, a peach, or any other polygon or a shape with at least one curved surface. In one embodiment, the weight pad 212 may be generally trapezoidal. In another embodiment, the weight pad 212 may be slightly rectangular. In addition, in another embodiment, the weight pad 212 may be slightly circular. Or, in another embodiment, the weight pad 212 may be slightly triangular.

在多數實施例中，配重墊212可為金屬材質，因而能夠提供密集的向後部分以改善高爾夫球桿頭100的整體MOI。在某些實施例中，配重墊212的材質可為不鏽鋼、鈦、鋁、鋼合金(例如455鋼、475鋼、431鋼、17-4不鏽鋼、馬釘鋼)、鈦合金(例如Ti 7-4、Ti 6-4、T-9S)、鋁合金或複合材料。在一實施例中，配重墊212可為不鏽鋼。配重墊212可經鍛造或鑄造製成，而後再固定於後本體108的底部件208內。 In most embodiments, the weight pad 212 can be made of metal, which can provide a dense rearward portion to improve the overall MOI of the golf club head 100. In some embodiments, the material of the weight pad 212 can be stainless steel, titanium, aluminum, steel alloy (such as 455 steel, 475 steel, 431 steel, 17-4 stainless steel, horse nail steel), titanium alloy (such as Ti 7 -4, Ti 6-4, T-9S), aluminum alloy or composite materials. In an embodiment, the weight pad 212 may be stainless steel. The weight pad 212 can be made by forging or casting, and then fixed in the bottom part 208 of the rear body 108.

配重墊212是經由一或多種可提供牢固結構結合的技術而固定在彈性層152中的開口250內。由於材料種類/材料表面能有所差異，加上組件質量與接觸表面積比較高，單純使用習知黏膠可能難以耐受高爾夫球桿撞擊高爾夫球期間產生的力量。為解決此一問題，可利用封裝配重墊的至少一部分來將配重墊的至少一部分整合於結構層156及/或彈性層152。如此一來，封裝層的材料強度可帶來較單獨使用表面黏膠更耐久可靠的結合效果。參照圖9及13，適合的封裝方式可包括以結構膠帶261包覆配重墊212的邊緣252、直接將配重墊的至少一部分212包裹在結構層156內或是將配重 墊的一部分包裹在彈性層152的相鄰夾層之間。上述技術可替代或搭配使用在配重墊與底部件208之間的化學黏膠。 The weight pad 212 is fixed in the opening 250 in the elastic layer 152 through one or more technologies that can provide a firm structural connection. Due to the difference in material types/material surface energy, and the relatively high component quality and contact surface area, it may be difficult to withstand the force generated by the golf club hitting the golf ball using conventional adhesives alone. To solve this problem, at least a portion of the encapsulated weight pad can be used to integrate at least a portion of the weight pad with the structural layer 156 and/or the elastic layer 152. In this way, the material strength of the encapsulation layer can bring about a more durable and reliable bonding effect than using surface adhesive alone. 9 and 13, suitable packaging methods may include wrapping the edge 252 of the weight pad 212 with a structural tape 261, directly wrapping at least a portion 212 of the weight pad in the structural layer 156, or wrapping the weight A part of the pad is wrapped between adjacent interlayers of the elastic layer 152. The above technology can be used in place of or in combination with the chemical glue between the weight pad and the bottom part 208.

在一種配置中，配重墊212可附加至底部件208而不使用任何機械式緊固件。在一實施例中，配重墊212為鑄造而成，且結構層156是經由例如埋入射出成形或共模技術而成形在配重墊212的至少邊緣252處。如上所述，結構層156的填料式熱塑性構造能夠形成複雜幾何形狀並以具有結構穩定性的方式圍繞邊緣延伸，因此特別適合用以承接配重墊212。取決於配重墊的幾何形狀，此種連接技術可能較難利用固定形狀的膠帶或FRC來實現。 In one configuration, the weight pad 212 may be attached to the bottom member 208 without using any mechanical fasteners. In one embodiment, the weight pad 212 is cast, and the structural layer 156 is formed at at least the edge 252 of the weight pad 212 through, for example, embedding injection molding or common mold technology. As described above, the filled thermoplastic structure of the structural layer 156 can form a complex geometric shape and extend around the edge in a structurally stable manner, so it is particularly suitable for receiving the weight pad 212. Depending on the geometry of the weight pad, this connection technique may be difficult to achieve with fixed-shape tape or FRC.

配重墊212凹腔216自配重墊212向內延伸。在圖示實施例中，凹腔216為圓形。在其他實施例中，凹腔216可包含任何形狀。例如，凹腔216形狀可包含圓形、橢圓形、三角形、矩形、八邊形或任何其他多邊形或具有至少一個彎弧表面的形狀。凹腔216形成一個可供金屬重物220固定於其中的陷槽。金屬重物220可對高爾夫球桿頭100添加自由設置重量，藉此進一步改善高爾夫球桿頭100的MOI及CG。此外，透過凹腔216及金屬重物220的設置，不同密度的不同金屬重物可活動附加於高爾夫球桿頭100以改變其整體重量。 The cavity 216 of the weight pad 212 extends inwardly from the weight pad 212. In the illustrated embodiment, the cavity 216 is circular. In other embodiments, the cavity 216 may include any shape. For example, the shape of the cavity 216 may include a circle, an ellipse, a triangle, a rectangle, an octagon, or any other polygon or a shape having at least one curved surface. The cavity 216 forms a recessed groove in which the metal weight 220 can be fixed. The metal weight 220 can add freely set weight to the golf club head 100, thereby further improving the MOI and CG of the golf club head 100. In addition, through the arrangement of the cavity 216 and the metal weight 220, different metal weights of different densities can be movably attached to the golf club head 100 to change its overall weight.

凹腔212的深度是從凹腔212基底224沿概與基底224垂直的方向而測量至底部件208外輪廓。在許多實施例中，凹腔212深度是介於0.10英吋及0.50英吋之間。在某些實施例中，凹腔212深度小於0.50英吋、小於0.45英吋、小於0.40英吋、小於0.35英吋、小於0.30英吋、小於0.25英吋、小於0.20英吋或小於0.15英吋。 The depth of the cavity 212 is measured from the base 224 of the cavity 212 along a direction substantially perpendicular to the base 224 to the outer contour of the bottom member 208. In many embodiments, the depth of the cavity 212 is between 0.10 inches and 0.50 inches. In some embodiments, the depth of the cavity 212 is less than 0.50 inches, less than 0.45 inches, less than 0.40 inches, less than 0.35 inches, less than 0.30 inches, less than 0.25 inches, less than 0.20 inches, or less than 0.15 inches. .

再者，凹腔212包含位在基底224中的孔洞228。孔洞228自凹腔212基底224往內朝向高爾夫球桿頭100冠部112延伸。在某些實施例中，孔洞228可包含與緊固件230螺紋相配的螺紋，以便將金屬重物220固定在凹腔216內。在其他實施例中，孔洞228可不具有螺紋，而是搭配自攻或自鑽緊固件使用。 Furthermore, the cavity 212 includes a hole 228 located in the substrate 224. The hole 228 extends inward from the base 224 of the cavity 212 toward the crown 112 of the golf club head 100. In some embodiments, the hole 228 may include threads that match the threads of the fastener 230 so as to fix the metal weight 220 in the cavity 216. In other embodiments, the holes 228 may not have threads, but are used with self-tapping or self-drilling fasteners.

金屬重物220可在配重墊212的凹腔216中設置定位。在圖示實施例中，重物220為圓形以對應凹腔212的形狀。在其他實施例中，重物220可包含任何對應於凹腔212形狀的幾何形狀(例如圓形、橢圓形、三角形、矩形、梯形、八邊形或任何其他多邊形或具有至少一個彎弧表面的形狀)。 The metal weight 220 can be positioned in the cavity 216 of the weight pad 212.

圖14描繪一實施例中高爾夫球桿頭100的製造方法300，此桿頭具有一體結合的彈性層152、結構層156及底部件208的金屬配重墊220。所述方法300包含在步驟310將一纖維加固式熱塑性複合材料熱成形為桿頭100的外殼部。熱成形程序可涉及，例如，將熱塑性預浸體預先加熱到至少高於該熱塑性聚合物玻璃轉化溫度的成形溫度、使該預浸體成形為殼部形 狀而後將成形的零件修整為適當大小。 FIG. 14 depicts a method 300 of manufacturing a golf club head 100 in an embodiment. This club head has a metal weight pad 220 with an elastic layer 152, a structural layer 156, and a sole member 208 integrally combined. The method 300 includes thermoforming a fiber-reinforced thermoplastic composite material into the outer shell portion of the club head 100 at step 310. The thermoforming procedure may involve, for example, preheating a thermoplastic prepreg to a forming temperature that is at least higher than the glass transition temperature of the thermoplastic polymer, and forming the prepreg into a shell shape. Shape and then trim the formed part to an appropriate size.

待複合材料殼部構成適當形狀後，在步驟320中，便可透過射出成形方式，使填料式聚合物支撐結構直接接觸殼體。此一工序通常稱為埋入成形。在此工序中，殼體是直接放置在加熱的模具內，此模具設有一暴露於部分殼體的帶閘凹腔。將熔化的聚合物強制注入凹腔，使其直接與加熱後複合材料殼體的熔化狀態聚合物混合，或使其局部與呈軟化狀態的殼體黏結。待模型冷卻，複合材料殼體及支撐結構的聚合物共同硬化而構成熔接關係。若殼部的聚合物及支撐結構的聚合物彼此相容，結合效果更佳，而若上述兩種組件包含共用的熱塑性樹脂組件，則結合效果又更進一步。雖然埋入成形是形成該結構的較佳技術，但亦可使用其他模製成形技術，例如壓縮成形。 After the composite shell has a proper shape, in step 320, the filler-type polymer support structure can directly contact the shell through an injection molding method. This process is usually referred to as buried forming. In this process, the shell is directly placed in a heated mold, and the mold is provided with a cavity with a gate exposed to part of the shell. The molten polymer is forcibly injected into the cavity, so that it is directly mixed with the polymer in the molten state of the heated composite material shell, or is partially bonded to the shell in a softened state. When the model is cooled, the composite shell and the polymer of the support structure harden together to form a welded relationship. If the polymer of the shell part and the polymer of the support structure are compatible with each other, the bonding effect is better, and if the above two components include a common thermoplastic resin component, the bonding effect is even further. Although embedded molding is a preferred technique for forming the structure, other molding techniques, such as compression molding, can also be used.

續參照圖14，經由步驟310及320形成底部件208之後，可將FRC冠部件204結合於底部件208以實質完成後本體108的結構(步驟330)。在一較佳實施例中，冠部件204的材質可為熱塑性FRC材料，並利用類似於步驟310所述的熱成形技術而構成所需形狀。以熱塑性複合材料製成的冠部件204可透過局部焊接技術結合於底部件208。上述焊接技術可為例如雷射焊接或超音波焊接，若該聚合物具有導電性，亦可使用電阻焊接。若冠部件204是以熱固性聚合物形成，則可利用例如黏膠或機械性固定技術(柱螺栓、螺絲、螺釘、機械性干涉嚙合等等)將冠部件204結合於底部件208。 14, after the bottom member 208 is formed through steps 310 and 320, the FRC crown member 204 can be combined with the bottom member 208 to substantially complete the structure of the back body 108 (step 330). In a preferred embodiment, the material of the crown member 204 can be a thermoplastic FRC material, and the thermoforming technique similar to that described in step 310 is used to form the desired shape. The crown part 204 made of thermoplastic composite material can be joined to the bottom part 208 by a local welding technique. The above-mentioned welding technique can be, for example, laser welding or ultrasonic welding. If the polymer is conductive, resistance welding can also be used. If the crown member 204 is formed of a thermosetting polymer, the crown member 204 can be bonded to the bottom member 208 by using, for example, glue or mechanical fixing techniques (studs, screws, screws, mechanical interference engagement, etc.).

繼而在步驟340中，可將包含固定後冠部件204及底部件208的後本體108黏結於金屬前本體104。雖然黏膠可以固定多數金屬，但可能需要使用一或多種助黏劑或表面處理來加強黏膠與後本體108聚合物之間 的結合。 Then in step 340, the rear body 108 including the fixed rear crown member 204 and the bottom member 208 may be bonded to the metal front body 104. Although the adhesive can fix most metals, one or more adhesion promoters or surface treatments may be required to strengthen the adhesive and the polymer of the rear body 108 The combination.

三、優點3. Advantages

利用混合材料後本體構造可大幅減輕結構重量，且無需犧牲任何設計靈活性，並提供一種重新導入自由設置質量的可靠方式。雖然此種設計可完全使用填料式熱塑性材料，例如聚苯硫醚(PPS)，製成如上所述，但使用纖維加固式複合材料則能夠在連續外表面上提供更強且更輕的構造。反之，全FRC設計無法輕易納入重物承接結構，因此無法輕易利用於增加自由設置質量。 The body structure using mixed materials can greatly reduce the structural weight without sacrificing any design flexibility, and provides a reliable way to reintroduce freely set quality. Although this design can be made entirely of filler-type thermoplastic materials, such as polyphenylene sulfide (PPS), as described above, the use of fiber-reinforced composite materials can provide a stronger and lighter structure on a continuous outer surface. On the contrary, the full FRC design cannot be easily incorporated into the heavy object receiving structure, so it cannot be easily used to increase the free setting quality.

擁有金屬配重墊的混合材料高爾夫球桿頭較未設有金屬配重墊者的優勢在於，所述金屬配重墊可供變化及更換金屬重物，同時提供耐久可靠的金屬重物裝設位置。相較於未設有金屬配重墊的高爾夫球桿頭，金屬配重墊可耐受加掛重物時作用在配重墊上的扭力。再者，金屬配重墊可供製造商透過更換金屬重物而調整製造公差(亦即使整體桿頭的理想揮桿重量在206公克至209公克之間變化)，或因應顧客需求規格而調整(例如高爾夫球員可使其桿頭加重，206公克至209公克)。 The advantage of a mixed-material golf club head with a metal weight pad over those without a metal weight pad is that the metal weight pad can be used for changing and replacing metal weights, while providing a durable and reliable metal weight installation Location. Compared with a golf club head without a metal weight pad, the metal weight pad can withstand the torsion force that acts on the weight pad when a weight is added. In addition, the metal weight pad allows manufacturers to adjust manufacturing tolerances by replacing metal weights (even if the ideal swing weight of the overall club head varies between 206 grams and 209 grams), or can be adjusted according to customer requirements ( For example, golfers can make their club head heavier, 206 grams to 209 grams).
