Description

Golf club hitting plate and golf club with the hitting plate Technical Field

[0001] The utility model relates to the field of sports equipment, and more particularly to a hitting plate of a golf club and a golf club with the hitting plate. Background Art

[0002] Prior art improvements to golf clubs have primarily focused on the club head. For example, to improve the club head's center of gravity and the degree of freedom associated with its moment of inertia during impact, the weight of a portion of the club head, particularly the portion closest to the blade, is reduced, thereby altering the club head's center of gravity and moment of inertia during the swing. However, as club head volume increases, thinner-walled designs weaken the structural strength of the club head (particularly the crown), leading to a current bottleneck in weight reduction efforts. While some efforts have focused on optimizing the blade attached to the club head, prior art has largely focused on improving the faceplate's contact surface, typically by adding grooves to enhance contact with the golf ball. These improvements include increasing friction, improving ball retention, and increasing the sweet spot area. In this process, various composite materials with excellent elasticity (such as titanium alloys) have also been incorporated into blades, particularly for the number one club, which prioritizes efficient kinetic energy conversion. However, while these improved elasticity come with the added drawback of increased brittleness, significantly impacting the durability of the blade.

[0003] In this regard, it is necessary to consider improving the hitting plate of the golf club to optimize the force transmission path when hitting the ball and improve its durability. Technical issues

[0004] The present invention aims to overcome at least one of the above-mentioned defects of the prior art, and one of its purposes is to provide a hitting plate for a golf club, so as to solve the problem that the hitting plate is easily broken. Technical Solutions

[0005] The technical solution adopted by the utility model is a hitting plate of a golf club. The hitting plate has a certain thickness. Two sides of the hitting plate in the thickness direction are respectively set as a hitting surface and a supporting surface, wherein the supporting surface is provided with a plurality of grooves.

[0006] In this embodiment, the end surface of the groove receives the striking surface of the blade, while the opening of the groove is located on the support surface of the blade. When a golf ball is struck with a club equipped with this embodiment, the impact force of the ball on the blade is quickly transmitted to the support surface through the groove structure and then distributed around the support surface, thereby improving the blade's force transmission performance and avoiding the problem of localized breakage caused by uneven force distribution. Furthermore, the grooves reduce the material usage of the blade, saving manufacturing costs. More importantly, they reduce the weight of the blade, helping to optimize the club head's center of gravity and the moment of inertia during the swing.

[0007] Furthermore, the batting plate is an amorphous alloy plate, a high entropy alloy plate, or a titanium alloy plate.

[0008] In this solution, amorphous alloy plates, high entropy alloy plates, and titanium alloy plates all have excellent mechanical properties, exhibit high plasticity when compressed and bent, and have both high strength and high fracture toughness. When used in the hitting plate of a golf club, amorphous alloy plates, high entropy alloy plates or titanium alloy plates have excellent elasticity, which can greatly improve the conversion efficiency of kinetic energy when hitting the ball. By combining with the above-mentioned groove structure, while achieving excellent hitting effect, it also has a certain structural strength, thereby improving service life.

[0009] Furthermore, the groove is a U-shaped groove or a nearly U-shaped groove, with its opening facing the supporting surface.

[0010] The side of the U-shaped groove facing the hitting surface has an arc surface, which can speed up the guidance of the impact force generated when the hitting plate hits the ball to the supporting surface.

[0011] Furthermore, the portion of the approximately U-shaped groove facing the ball hitting surface has a rounded corner structure.

[0012] Through the rounded corner structure, the path length in all directions between the part of the U-shaped groove abutting the hitting surface and the opening facing the support surface is the same, so that the impact force when the hitting plate hits the ball can be guided to the support surface with high uniformity everywhere.

[0013] Furthermore, the U-shaped groove or the opening of the approximately U-shaped groove has a receiving section that receives the support surface, and the receiving section is a circular arc section.

[0014] Preferably, the arc segment bends outward from the hitting surface to the supporting surface.

[0015] The arc segment design of this solution allows the impact force transmitted to the opening of the U-shaped groove to quickly spread to the surrounding of the supporting surface, and finally guide to the club or other device where the hitting plate is set.

[0016] Furthermore, the groove is hemispherical with its opening facing the supporting surface.

[0017] When a golf ball is struck by a club equipped with the present invention, the impact force is transmitted inward from the front of the striking surface. After receiving the impact force through the hemispherical top, the impact force is transmitted to the supporting surface. Since the arc-shaped transmission path between the hemispherical top and the supporting surface is the same length, the impact force is evenly transmitted to all parts of the striking plate, so that the entire striking plate is evenly stressed, avoiding local excessive stress, and helping to increase the service life.

[0018] Optionally, the radius of the hemispherical / rounded corner or arc segment is 0.5 mm-3.0 mm.

[0019] When this size is set, the batting plate can obtain a better force transmission effect and can reduce the complexity of processing.

[0020] Preferably, the grooves are evenly distributed on the supporting surface.

[0021] This solution allows the impact energy received by the hitting plate when hitting the ball to be evenly transmitted to the four sides of the hitting plate. Part of the impact energy is absorbed by the deformation of the hitting plate, and the other part of the impact energy is transmitted to the ball head on which the hitting plate is set. The hitting plate is subjected to uniform force everywhere, thereby avoiding local damage and breakage caused by uneven force, thereby improving the durability of the hitting plate.

[0022] Preferably, the grooves are densely distributed on the supporting surface.

[0023] The densely distributed grooves can reduce the distance between adjacent grooves, so that the supporting surface has higher energy conduction efficiency.

[0024] Furthermore, the support surface gradually rises from the periphery to the middle to form a convex surface.

[0025] This solution uses a convex structure to achieve better support strength when the hitting plate support is set on the adapted golf club head.

[0026] Furthermore, a connecting portion is provided around the supporting surface, and the hitting plate is arranged on the golf club through the connecting portion.

[0027] Preferably, the connecting portion is arranged around the supporting surface.

[0028] This solution can increase the contact area between the support portion and the golf club body, thereby improving the support strength when the striking plate is set on the golf club body.

[0029] Preferably, the connecting portion and the supporting surface are integrally formed.

[0030] This solution can reduce the processing complexity of the hitting plate, reduce costs, and also improve the supporting strength.

[0031] Furthermore, the hitting plate has a thickness of 2.0 mm to 7.0 mm.

[0032] The dimensions of this solution can make the hitting plate have a light structure while ensuring a certain structural strength, so that the golf club provided with the hitting plate can obtain an excellent hitting effect, and also have the durability of the hitting plate.

[0033] Another object of the present invention is to provide a golf club having the golf club hitting plate. Beneficial effects

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: by providing grooves on the supporting surface, the transmission efficiency of the impact force received by the hitting plate when hitting the ball is improved, the overall force uniformity of the hitting plate is improved, which helps to obtain a good hitting effect and increase the service life of the hitting plate; secondly, by making the receiving section of the groove on the supporting surface an arc section, the efficiency of the impact force transmitted to the supporting plate to the surrounding area of ​​the supporting plate is accelerated; in addition, by using an amorphous alloy plate, a high entropy alloy plate or a titanium alloy plate as the hitting plate for the groove, the elasticity of the hitting plate is improved, thereby obtaining a better kinetic energy conversion rate when hitting the ball, and the combination with the groove structure can ensure high performance without sacrificing the service life of the hitting plate.

[0041] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings. Example 1

[0042] As shown in Figures 1-3, this embodiment provides a golf club blade 2. The blade 2 has a certain thickness. Two sides of the blade 2 in the thickness direction are respectively defined as a striking surface 21 and a support surface 22. The support surface 22 is provided with a plurality of grooves 23. In practice, to ensure a lightweight structure while maintaining a certain level of structural strength, the thickness of the blade 2 can be set between 2.0 mm and 7.0 mm. Furthermore, the striking surface 21 of the blade 2 can also be provided with grooves, protrusions, and other structures to enhance the contact between the striking surface 21 and the ball during impact, such as increasing friction and improving sustain, thereby making the impact more controllable and stable.

[0043] During use, the inner end surface of the groove 23 receives the striking surface 21 of the striking blade 2, while the opening of the groove 23 is located on the supporting surface 22 of the striking blade 2. When a golf ball is struck using a club equipped with the striking blade 2 of this embodiment, the impact force of the ball on the striking blade 2 is quickly transmitted to the supporting surface 22 through the groove 23 and then distributed around the supporting surface 22. This improves the force transmission performance of the striking blade 2 and avoids the problem of localized breakage caused by uneven force distribution. Furthermore, the provision of the groove 23 reduces the material usage of the striking blade 2, saving manufacturing costs. More importantly, it also reduces the weight of the striking blade 2, helping to optimize the center of gravity of the club head and the moment of inertia during the swing, thereby achieving a better hitting effect.

[0044] In a preferred embodiment, the grooves 23 are evenly arranged on the supporting surface 22. When in use, the impact energy received by the hitting plate 2 when hitting the ball is evenly transmitted to the four sides of the hitting plate 2. Part of the impact energy is absorbed by the deformation of the hitting plate 2, and the other part of the impact energy is transmitted to the ball head on which the hitting plate 2 is provided. The hitting plate 2 is subjected to uniform force at all parts, thereby avoiding local damage and breakage caused by uneven force, thereby improving the durability of the hitting plate 2.

[0045] In a more preferred embodiment, the grooves 23 are densely distributed on the support surface 22. When in use, the densely distributed grooves 23 can reduce the distance between adjacent grooves 23, so that the support surface 22 has a higher energy conduction efficiency, and further reduce the material usage of the hitting plate 2, which can reduce its weight, thereby improving the hitting effect.

[0046] In order to improve the hitting performance of the hitting plate 2, the hitting plate 2 of this embodiment can be made of an amorphous alloy plate, a high entropy alloy plate, or a titanium alloy plate.

[0047] Amorphous alloys are produced by ultra-rapid cooling and solidification. During solidification, the atoms in the alloy do not have time to arrange themselves into orderly crystals. The resulting solid alloy has a long-range disordered structure. The molecules (or atoms, or ions) that make up the alloy lack regular spatial periodicity, and the grains and grain boundaries found in crystalline alloys are absent. In terms of mechanical properties, amorphous alloys possess extremely high strength and hardness, but a low elastic modulus. Unlike metallic glass, which exhibits low elongation when stretched, amorphous alloys exhibit high plasticity when compressed and bent. Therefore, they possess both high strength and good toughness. When made into a batting blade 2, amorphous alloys can effectively absorb the impact energy of a ball, enhancing its durability.

[0048] High-entropy alloys are typically composed of five elements, with the atomic percentage of each element ranging from 5% to 35%. Broadly speaking, alloys containing four or more elements, with three or more being primary elements, are generally considered high-entropy alloys. Mechanically, high-entropy alloys typically exhibit high fracture toughness, so the batting blade 2 made from them can effectively absorb the impact energy received during hitting the ball, thereby improving durability.

[0049] The titanium alloy plate has the advantages of high strength and low density, good mechanical properties, excellent toughness and corrosion resistance, and is also suitable for use as the hitting plate 2.

[0050] It can be understood that amorphous alloy plates, high entropy alloy plates or titanium alloy plates all have excellent mechanical properties, show high plasticity when compressed and bent, and have both high strength and high fracture toughness. When used in the hitting plate 2 of a golf club, they have more superior elasticity, which can greatly improve the conversion efficiency of kinetic energy when hitting the ball. By cooperating with the above-mentioned groove 23 structure, while achieving excellent hitting effect, they also have a certain structural strength, thereby improving the service life.

[0051] In some preferred embodiments, the groove is a U-shaped groove or a nearly U-shaped groove, with the opening facing the support surface. When used, the U-shaped groove has a curved surface on the side facing the hitting surface, which can accelerate the guidance of the impact force generated by the hitting plate 2 when hitting the ball to the support surface.

[0052] In a more preferred embodiment, the portion of the approximately U-shaped groove facing the ball striking surface has a rounded corner structure. This rounded corner structure ensures that the path length between the portion of the U-shaped groove abutting the ball striking surface and the opening facing the support surface is uniform in all directions. This ensures that the impact force of the striking plate 2 when striking the ball is directed to the support surface with high uniformity. Furthermore, the rounded corner structure provides excellent support for the ball striking surface.

[0053] As shown in Figure 1, the U-shaped groove or the opening of a nearly U-shaped groove has a receiving section 24 that receives the support surface. The receiving section 24 is an arc section, which bends outward from the hitting surface 21 to the support surface 22. When in use, the arc section structure allows the impact force transmitted to the opening of the U-shaped groove to quickly diffuse to the surrounding area of ​​the support surface, and finally guide to the club or other device on which the hitting plate 2 is set.

[0054] Furthermore, in some embodiments, the groove 23 may be configured to be hemispherical.

[0055] When a golf ball is struck by a golf club equipped with the present embodiment, the impact force is transmitted inward from the front of the striking surface 21 and first passes through the hemispherical top. Since the arc-shaped conduction path between the hemispherical top and the support surface 22 is the same length, the impact force is evenly transmitted to all parts of the striking plate 2 during the process of receiving the impact and transmitting it to the support surface 22. This ensures that the entire striking plate 2 is subjected to uniform force, avoids local excessive force, and helps to increase the service life.

[0056] In a specific implementation, the radius of the hemispherical, chamfered groove or arc segment is 0.5 mm to 3.0 mm. By setting this size, the hitting plate 2 can obtain a better force conduction effect.

[0057] As shown in FIG1 , the support surface 22 gradually rises from the periphery to the center to form a convex surface. The convex surface structure enables the striking plate 2 to obtain better supporting strength when supported on an adapted golf club head.

[0058] Furthermore, a connecting portion 25 is provided around the support surface 22. During use, the golf club head typically includes a recessed structure for receiving the striking blade 2, which is positioned within the recessed structure via the connecting portion 25. In practice, the connecting portion 25 is disposed around the support surface 22 to increase the contact area between the supporting portion and the golf club body, thereby enhancing the support strength of the striking blade 2 when mounted on the golf club body. Furthermore, to reduce manufacturing complexity, in a preferred embodiment, the connecting portion 25 is integrally formed with the support surface 22, further enhancing support strength. Example 2

[0059] As shown in Figures 4-5, this embodiment provides a golf club 1 having a blade 2 of the golf club 1 described in Example 1. The golf club 1 includes a connected club shaft and a club head 3. The club head 3 defines a cavity 31 that mates with the blade 2, and the blade 2 is positioned within the cavity 31. Specifically, a support portion 32 is formed around the inner periphery of the cavity 31. When the blade 2 is positioned within the cavity 31, the connecting portion 25 of the blade 2 rests on the support portion 32 of the cavity 31, thereby providing stable support for the blade 2. Furthermore, to ensure the strength of the connection between the blade 2 and the club head 3, welding, gluing, or a connector between the blade 2 and the club head 3 can be employed.

[0060] During specific use, when the golf club 1 is swung to hit the golf ball, the striking surface 21 of the striking plate 2 is subjected to the impact force of the golf ball and is then transmitted to the supporting surface 22. During the transmission process, the impact force is absorbed by the rounded corner or hemispherical structure of the groove 23 toward the striking surface 21 and then evenly diffused to the supporting surface 22. Then, the impact force is rapidly diffused to the surrounding areas of the supporting surface 22 through the arc-shaped connecting section 24 between the groove 23 and the supporting surface 22. Finally, part of the impact force is absorbed by the deformation of the striking plate 2 itself, and the other part of the impact force is efficiently transmitted to the club head 3 structure of the golf club 1 on which the striking plate 2 is set. The striking plate 2 of the present invention can optimize the transmission path of the impact force. At the same time, the specially designed groove 23 can provide good support for the striking plate 2, reduce the amount of consumables of the striking plate 2, and reduce its weight, thereby optimizing the hitting effect of the golf club 1. In addition, the hitting plate 2 of the present invention adopts an amorphous alloy plate, a high entropy alloy plate, or a titanium alloy plate with superior performance, which reduces the weight of the hitting plate 2 while also improving the elasticity of the hitting plate 2. Combined with the above-mentioned groove 23 structure, the hitting performance of the golf club 1 equipped with the hitting plate 2 of the present invention can be greatly improved.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
