More particularly, the present invention relates to a golf club head having a main body made of a metal bismuth jade material, which is more effective for impact. The transmission of energy to the Gao Tongerfu ball and a non-metallic auxiliary body to control the mass distribution. Related technical description When the golf club head hits the golf ball, a large impact force is generated on the club head and the golf ball. However, Most of the energy is converted from the head to the golf ball-some energy is lost as a result of the collision. Golf balls are typically composed of a polyester cover material (such as an ionomer) surrounding a rubber-type core. This The softer polymer material has a deformation attenuation (loss) property and a deformation rate based on ί-loo times greater than that of the metal club surface. Therefore, during a collision, its small deformation relative to the surface of the metal club (〇〇 25 to 0.050 inches), most of the energy is lost due to high stress results and golf ball deformation (0.001 to 0.20 inches). More efficient energy conversion from the golf club head to the golf ball results in a larger flight distance of the golf ball The generally accepted method has increased the steepness of the club head surface and decreased -5- This paper size applies to China National Standard (CNS) Α4 size (210X297 mm) binding

Invention Explanation (16) The windability of the striking plate segment 72 is strengthened, which corresponds to less energy loss to the golf ball and a larger coefficient of restoration. Preferably, the main body 50 is cast from molten metal, such as a conventional lost wax. The method is used to make the metal. The metal used for forming is preferably 17-4 stainless steel. An additional method for manufacturing the main body 50 includes making the main body 50 from a flat metal sheet, and making the main body from a super flat plastic sheet. 50, machining the body 50 from a solid metal, electrochemically machining the body 50 from a preform made of Ik, and the same manufacturing method. Progressive methods include diffusion bonding titanium or steel sheets to produce a variable thickness surface, and then Made of super plastic. The present invention is a guide golf club head with a high coefficient of recovery, thereby enabling the golf ball to have a larger distance when it hits the golf club head of the present invention. The coefficient of recovery (also referred to herein as C〇 R) is determined by the following equation e ^ (v ^ ViA ^ -U2), where the ratio of the ratio of the club head before impacting it; the speed of the mountain golf before impact, which is zero; Vi system golf The velocity of the club head just after being separated from the surface of the club head; W is the velocity of the golf ball after the surface of the golf ball is just separated from the surface of the club head; and e is the coefficient of restoration between the golf ball and the surface of the club head. The value is limited to zero and 10 when no external energy is applied to the system. For materials such as soft clay or putty, the recovery coefficient e will be close to zero, and for completely elastic materials, when there is no energy loss after deformation, its e value will be Is 10. The present invention provides a club head with a coefficient of restoration in the range of 〇8 丨 to 094, which is measured under general test conditions.

The range is from 15 grams to just grams, and the better range of X is from 155 grams to 166 grams, and the best range is 6 gram. The preferred range of the second edition of 60 is from 4 grams to 20 grams, and the better range is from $ Gram to 1) grams' is best 7 grams. The mass of the rear weight member 122 preferably ranges from 1 gram to 5G grams, more preferably 3G grams to buckles, and most preferably 31 grams. Rod elbow The weight member 123 preferably has a mass ranging from 2 g to 15 g, more preferably 3 g to g, and most preferably 5 g. In addition, the number i of epoxy resin or other flowable material can range from 0.5 g to 5 g, which can be shot into the hollow interior 46 of the golf club head 40 for its selective weight. 10 and 10A illustrate the inertia axis passing through the center of gravity of the golf club. Inertial shafting is marked X, Y, and Z. The X-axis extends from the striker segment 72 through the center of gravity CG to the rear of the golf club head 40. The gamma axis extends from the club tip 40 of the golf club head 40 through the center of gravity CG to the elbow end 66 of the golf club head 40. The Z axis extends from the crown section 62 through the center of gravity CG to the bottom section 76. As Ralph Maltby's Golf Design, Accessories, Replacement and Repair 4th Edition means, the center of gravity or center of mass of a golf club head is a point on the inside of the club head, which is balanced when the club head is suspended, Determined by two or more vertical crossings. A more complete explanation of this focus definition is provided for golf design, fittings, replacements, and repairs. The center of gravity and moment of inertia of the golf club head 40 are preferably measured using test space coordinates (XT, Ydding, ZT), and then converted to head space coordinates (χΗ, γΗ, ZO), as shown in Figures 1 1 and 1 1Α As shown. The center of gravity of the golf club head is available with two -21-
