In addition, the top portion of the hub 71 has the same thickness as the ring wall 711 of the hub 71. The inner wall surface of the ring wall 711 is axially formed with a plurality of coupling ribs 712. The outer diameter of a metal ring 8 is gradually enlarged from a first end 81 of the metal ring 8 toward a second end 82, and the first end 81 extends radially inward to form a ring lip 83 so that a magnet ring 9 When it is bonded to the inner wall surface of the metal ring 8, it can abut against the ring lip 83. Referring to FIGS. 1 and 2 again, since the outer diameter of the first end 81 of the metal ring 8 is slightly smaller than the inner diameter formed by the coupling rib 712 of the hub 71, the outer diameter of the second end 82 is slightly The inner diameter formed by the coupling rib 712 of the hub 71 is greater than the first inner end 81 of the metal ring 8 when the metal ring 8 is assembled into the rotor 7. [Unlabeled]; then, the external force is used to continuously force the metal PK10392 07/07/24 200906027 ring δ into the internal space until the (four) stop 'At this time the second end 82 of the metal ring 8 is: tightening = 71 疋 is located in each of the combined ribs 712 " Further, the filament is formed into a plastic wheel; ^^1 'The above-mentioned fan wheel structure has a lower point, for example, the top of the rim 71 usually has a sufficient thickness, and the wheel cap 71 is closer to the axis position avoidance = The situation occurs, and because of the round of teaching the ring wall 12:: crack degree (four) at the top of the trough 71, the thickness of the thickness of the valley is easy to form a plastic expansion to make the metal ring 8 enter, so 711, The inner wall surface of the wall 711 is provided with the joint rib 712 to read the ring plastic deformation capability, so that the metal ring 8 is tightly fitted into the core rib, so that the metal ring 8 needs to be specially ordered. The two ends of the metal ring 8 are formed to have different outer diameters. Therefore, it is customary to perform a plurality of pre-assembly processing operations for the above reasons, and it is indeed necessary to further improve. In view of the above, the present invention improves the above-mentioned disadvantages, such that the substantial thickness of the ring step is smaller than the essence of the cap-top portion of the fan wheel, which reduces the ring wall portion. The substantial thickness, and thus the plasticity of the metal, is such that the metal body is tightly fitted into the space surrounded by the wall portion, so that the present invention has a tangible effect. ^...有衣w易' 叫郎省材料耗[Summary] PK10392 07/07/24 200906027 The main object of the present invention is to provide a fan wheel structure (-), the thickness of a ring wall of a dragon / a fan wheel Less than the thickness of a cover portion of the fan wheel, thereby reducing the substantial thickness of the ring wall portion, thereby improving the tamping deformation ability, so that the metal ring body is tightly fitted to form a ship. Easy, and at the same time save material costs. A stator wheel structure (1) according to the present invention comprises a hub, a number 4, a blade and a metal ring body connected to the outer circumferential surface of the hub. The solid f further has a top cover portion, a ring wall portion and a shaft base, the = wheel::: the outer periphery of the cover portion and the inner portion of the top cover portion and the ring two, the shaft base The seat is placed in the device 'and located in the internal space. In addition, the actual position of the ring wall portion is smaller than that of the top cover portion, and the bedding degree is assembled in the inner space. Other purposes are only 5. The following is a better description of the present invention. The following is a detailed description of the following: e. For the sub-combination, please refer to the figure shown in Figure 3 for a plastic material (for example, 7 cases of "fan wheel 1 ether ketone, etc.] use injection molding: one:, wide propylene, resin and poly-axial flow fan wheel or two, shape 'and it can be selected as a fan wheel Real fan blades 12 and - shaft production /, with - wheel hub 11, . Guhai fan 苇 d # 亍, 'The hub η system is in the middle of the 'mouth' a certain 2 series to equidistant 壬 ΡΚ 10392 07/ 07/24 (4) is connected to the outer circumference of the volute 11 on the surface of the 200906027; the shaft 13 is coupled to the axial center of the hub 11. Referring to Figures 3 and 4, the hub 11 of the first embodiment of the present invention is shown. The utility model has an inner space 110, a top cover portion 111, a ring wall portion 112 and a shaft base 113; the inner space 110 is composed of the top cover portion 111 and the ring wall The portion 112 is defined by a metal ring body 2 and a ring magnet 3 correspondingly assembled and embedded; the ring wall portion 112 is formed by bending downward from the outer periphery of the top cover portion 111; the shaft The rod base 113 is disposed at the axial center of the hub 11 and is located in the inner space 110 for the shaft rod 13 to be coupled and positioned. In addition, the substantial thickness T2 of the annular wall portion 112 is smaller than the top cover portion 111. The thickness of the metal ring is 2, and the metal ring body 2 of the present embodiment is assembled in the inner space 110 of the hub 11 in a tight fit manner, and the ring magnet 3 is correspondingly embedded in the metal ring. One of the annular magnets 3 is disposed in the accommodating space 20, and the one end of the annular magnet 3 is fixed to the accommodating space 20: The outer diameter of the metal ring body 2 is preferably slightly larger than the inner diameter of the inner space 110. Since the annular wall portion 112 of the hub has a thickness T2 which is relatively thinner than the thickness of the top cover portion 111, the ring wall portion 112 can be Corresponding to the metal ring body 2 to provide a better plastic deformation ability, so that the metal ring body 2 is easy The inner ring space 110 is forced into the inner space 110 by a tight fit, and when the metal ring body 2 is completely embedded in the inner space 110, the ring wall portion 112 also provides a resilient restoring force to securely fix the metal ring body 2 In the inner space 110, the metal ring body 2 is thereby closed to the ring magnet 3 to avoid magnetic leakage; at the same time, the metal ring body 2 is used to support the ring wall portion PK10392 07/07/24 — g — 200906027 112 inner wall surface, while reinforcing the overall structural strength of the annular wall portion 112 having a substantial thickness Τ2 which is relatively thinner than the top cover portion Π1. Referring to FIGS. 4 and 5 again, since the present invention utilizes the reduction of the substantial thickness Τ2 of the annular wall portion 112, the substantial thickness Τ2 of the annular wall portion 112 is smaller than the substantial thickness Τ1 of the top cover portion 111, thereby reducing the The overall weight of the annular wall portion 112, thereby reducing the overall weight of the fan wheel 1, while further reducing the thickness error generated when the annular wall portion 112 is injection molded, and avoiding uneven weight on the outer peripheral portion of the hub 11. 5 This can effectively improve the balance accuracy of the fan wheel 1 while saving the materials required to form the hub 11.
