Description

Technical Field

[0001] The present invention relates to a golf club head, and in particular to a golf club head. Background Art

[0002] In order to improve the hitting performance of golf clubs and reduce the impact feedback on the player's hands when hitting the ball, in the currently known club head structures, multiple cavities are formed inside the hitting panel to make the hitting panel elastic and easy to bend, or a buffer component with buffering elasticity is installed on the back of the hitting panel to reduce the impact force when hitting the ball.

[0003] Although the above-mentioned known golf club heads utilize the structure of forming a cavity inside the above-mentioned striking panel or providing a buffer component on the back of the striking panel to reduce the impact force when hitting the ball, the structure of forming multiple cavities inside the striking panel to provide an elastic structure that is easy to bend has a limited effect on reducing the impact force when hitting the ball; as for the structure of installing a buffer component with buffer elasticity on the back of the striking panel, an open cavity must be formed on the back of the striking panel, making it difficult to set the buffer component at an appropriate position on the back of the striking panel, and it is also difficult to play an appropriate buffering and shock-absorbing function during the striking process. Therefore, when hitting the ball, the shock force generated after the impact will still be transmitted to the player's hand along the shaft, thereby affecting the feel after hitting the ball. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a golf club head to solve the problem that when the existing golf club head hits the ball, the shock generated by the impact is transmitted to the player's hand along the shaft, thereby affecting the feel after hitting the ball.

[0031] The following is a further description of the technical means adopted by the present invention to achieve the predetermined purpose of the invention with reference to the accompanying drawings and embodiments of the present invention.

[0032] like Figure 1 and Figure 2 FIG. 1 shows an embodiment of a golf club head according to the present invention. Figure 1 , Figure 2 It can be seen that the golf club head includes a club head body 10 and a ball striking panel 20 .

[0033] like Figures 1 to 3 As shown, the club head body 10 is a component made of metal material, carbon fiber material or other materials, and a panel mounting groove 11 is formed at the front end of the club head body 10. The front end of the club head body 10 has a rod connecting portion 12 protruding upward. The bottom or rear end of the club head body 10 can be provided with at least one weight component according to the needs of the club head product.

[0034] like Figures 1 to 3 As shown, the striking panel 20 is fixedly arranged in the panel assembly groove 11 of the club head body 10 by means of welding or bonding. The striking panel 20 includes a panel body 21 and a filling member 22. The panel body 21 is an integrally formed member. Figures 3 to 8As shown, the panel body 21 is provided with a hitting area 2101 and an outer ring area 2102 located outside the hitting area 2101. A chamber 211 is formed inside the panel body 21. The position of the chamber 211 corresponds to the hitting area 2101 of the hitting panel 20. The hitting area 2101 of the panel body 21 has a front side wall 212 and a rear side wall 213 respectively relative to the front and rear sides of the chamber 211. The panel body 21 is formed with an injection port 214 and an air escape port 215 connected to the chamber 211 in the rear side wall 213 located at the rear side of the chamber 211. Preferably, the diameter of the air escape port 215 is smaller than the diameter of the injection port 214, and the air escape port 215 is spaced apart from the injection port 214. In this embodiment, the air escape port 215 and the injection port 214 are respectively arranged at the left and right sides of the chamber 211.

[0035] like Figure 8 As shown, the filling component 22 is filled in the chamber 211 by injecting a predetermined amount of a filling material through the injection port 214. The filling material may be silica gel or a high molecular polymer, etc. In one embodiment, the injection amount of the filling material is 0.2g to 5.5g. The injection port 214 and the air escape port 215 can be fixed and formed after the filling material is injected into the chamber 211. In the process of injecting the filling material into the chamber 211 through the injection port 214, the air originally located in the chamber 211 is discharged through the air escape port 215 due to the injection of the filling material into the chamber 211, so that the filling material can be completely filled in the chamber 211. The injection port 214 and the air escape port 215 can be fixed and formed after the filling material is injected into the chamber 211, and maintained in an open state, or closed with plugs respectively.

[0036] The panel body 21 can be made of suitable materials, such as metal materials or non-metal materials, according to the requirements of the club head product design. In this embodiment, the panel body 21 can be made of metal materials and realized by 3D printing integrated forming means. The specific materials are stacked layer by layer and solidified by 3D printing means, so that the panel body 21 can directly form a cavity 211 in an integrated manner, and the back side wall 213 on the back of the cavity 211 forms an injection port 214 and an air escape port 215 connected to the cavity 211. Thus, the panel body 21 can easily realize a hollow structure with a cavity 211 inside, which is difficult to be made by forging, stamping or other mechanical processing means. Moreover, the shape of the cavity 211 can be changed according to different hitting performances.

[0037] like Figures 3 to 8As shown, in the above, the chamber 211 includes a central section 2110 and a peripheral section 2111 surrounding the central section 2110. The depth of the chamber 211 in the front-to-back direction may be equal, or the depth of the chamber 211 in the front-to-back direction is the depth of the central section 2110, and the depth of the central section 2110 is greater than the depth of the peripheral section 2111 in the front-to-back direction, or the depth of the chamber 211 in the front-to-back direction is equal to the depth of the central section 2110, and the peripheral section 2111 is in a state of decreasing depth from the periphery adjacent to the central section 2110 toward the outer periphery of the peripheral section 2111. In this way, the thickness of the front side wall 212 of the panel body 21 located at the front side of the chamber 211 corresponding to the central section 2110 is greater than the thickness of the corresponding outer ring area 2102, and the thickness of the front side wall 212 corresponding to the outer ring area 2102 increases from the outer periphery adjacent to the central section 2110 toward the outside. The thickness of the rear side wall 213 of the panel body 21 located at the rear side of the cavity 211 is uniform, so that the filling component 22 disposed in the cavity 211 can be integrated with the panel body 21 to form a composite structure, and can better exert the excellent performance when hitting the ball.

[0038] like Figures 3 to 8 As shown, in this embodiment, the thickness of the outer ring area 2102 of the panel body 21 outside the cavity 211 is less than the thickness of the hitting area 2101 with the cavity 211 inside. The thickness t1 of the outer ring area 2102 of the panel body 21 outside the cavity 211 is 2 mm to 3 mm, preferably, the thickness t1 of the outer ring area 2102 of the panel body 21 outside the cavity 211 is 2.4 mm or 2.5 mm. The thickness t2 of the front side wall 212 of the panel body 21 located in front of the cavity 211 in the corresponding central section 2110 is 1.2 mm to 1.8 mm, preferably, the thickness t2 of the front side wall 212 of the panel body 21 located in front of the cavity 211 in the corresponding central section 2110 is 1.4 mm or 1.5 mm. The depth d1 of the central section 2110 of the cavity 211 is 1.5 mm to 2.5 mm, preferably, the depth d1 of the central section 2110 of the cavity 211 is 2.0 mm. The thickness t3 of the rear side wall 213 of the panel body 21 located at the rear side of the cavity 211 is 0.8 mm to 1.0 mm. Preferably, the thickness t3 of the rear side wall 213 of the panel body 21 located at the rear side of the cavity 211 is 0.9 mm. Thus, the thickness of the composite structure of the striking face plate 20 is controlled in a preferred implementation state.

[0039] To sum up, the golf club head of the present invention mainly utilizes the cavity 211 formed in the panel body 21 integrally formed in the striking panel 20, and fills the cavity 211 with a formed filling component 22, and can control the filling component 22 to be set at the striking area 2101 position of the striking panel 20, thereby enabling the filling component 22 to provide a shock absorbing effect, reduce the impact force of the ball, improve the hitting feel, and enable the striking panel 20 to increase its rebound coefficient, thereby enhancing the hitting performance such as the flight distance of the golf ball after being hit.

[0040] In addition, the golf club head of the present invention utilizes a cavity 211 formed in the panel body 21 integrally formed in the striking panel 20, and an injection port 214 and an air escape port 215 connected to the cavity 211 are formed on the back of the panel body 21. Filling material can be directly injected into the cavity 211 through the injection port 214, and the air originally in the cavity 211 is naturally discharged through the air escape port 215 due to the injection of the filling material into the cavity. The filling material can fill the cavity 211, so that the striking panel 20 forms a composite structure of different materials, thereby enhancing the simplicity of manufacturing the composite structure of the striking panel 20.
