BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a golf club head. In particular, the present invention relates to a wood-type golf club head. [0003] 2. Description of Related Art [0004] U.S. Pat. No. 6,491,592 discloses a multiple material golf club head comprised of a face component and an aft-body. The face component is composed of a single piece of metal and includes a striking plate portion and a return portion extending laterally inward from the perimeter of the striking plate portion. The aft-body has a crown portion and a sole portion. The crown portion includes a crown under portion which is mounted under the return portion to enhance the flexibility of the striking plate portion, providing a greater coefficient of restitution (COR). The crown portion further includes a thicker section following the crown under portion and a thinner remaining portion having a thickness the same as that of the crown under portion. The crown portion and the sole portion are engaged with the return portion and made from materials different from that of the return portion. [0005] Multiple material wood-type golf club heads are popular among golf players. However, the impact-resistance property of the crown portion of the above-mentioned wood-type club head is not improved. The present invention is intended to provide a solution in this regard. OBJECT OF THE INVENTION [0006] An object of the present invention is to provide a wood-type golf club head with improved impact-resistance property. SUMMARY OF THE INVENTION [0007] In accordance with an aspect of the present invention, a wood-type golf club head comprises a body and a crown plate. The body includes a striking face and a crown. An opening is defined in the crown of the body. The crown further includes an engaging section between a front edge delimiting the opening and a top end of the striking face. The crown plate is bonded to the crown of the body and covers the opening of the body. The crown plate includes a front engaging portion having a thickness greater than a remaining portion of the crown plate. The front engaging portion is bonded with the front engaging section of the body for improving impact-resistance property of the crown plate. [0008] Preferably, the crown plate includes a plurality of layers made of light metals or light non-metal light materials. The layers may be made of materials selected from the group comprising aluminum, magnesium, titanium, aluminum alloy, magnesium alloy, titanium alloy, carbon fibers, and Kevlar fibers. [0009] In an embodiment, the front engaging portion of the crown plate includes a length ranging from 10 mm to 40 mm, the front engaging portion of the crown plate includes a thickness ranging from 0.6 mm to 1 mm, and the remaining portion of the crown plate includes a thickness ranging from 0.4 mm to 0.8 mm. [0010] Preferably, the front engaging portion of the crown plate includes a length greater than that of the engaging section of the body. [0011] In an embodiment of the invention, the front engaging portion of the crown plate includes a front end that is flush with the striking face of the body. The front engaging portion of the crown plate is bonded with an upper face of the engaging section of the body. [0012] In another embodiment of the invention, the engaging section of the body includes a recessed portion communicated with the opening, and the front engaging portion of the crown plate is engaged with the recessed portion. The recessed portion of the engaging section of the body faces outward. The crown portion has a length greater than that of the recessed portion of the engaging section of the body. [0013] Other objects, advantages and novel features of this invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
