Motor rotating part

The present invention relates to a rotating member, and more particularly to a motor rotating member that can incorporate a permanent magnet as a rotor of a motor.

Referring to FIG. 1 , it is a patent of the "Pivot Structure of a Small Motor Rotor" of the Republic of China Announcement No. 443671, which discloses a conventional motor structure. The motor 8 generally includes a housing 81 and a stator. 82 and a rotor 83. The housing 81 is coupled to a shaft tube 811; the stator base 82 is coupled to the shaft tube 811 of the housing 81; the rotor 83 includes a hub 831, a spindle 832 and a permanent magnet 833; the hub 831 is integrally molded and coated. One end of the mandrel 832, the other end of the mandrel 832 is rotatably coupled to the shaft tube 811, and the permanent magnet 833 is coupled to the inside of the hub 831; thereby, the stator seat 82 can be used to drive the magnetic field after being energized to generate the magnetic field. The rotor 83 is rotated.

The hub 831 of the above-described conventional motor 8 is covered with the mandrel 832 by integral injection molding, and then the mandrel 832 is coupled into the shaft tube 811. However, in view of various conventional motor structures currently available on the market, there are still some motor structures that are not suitable for assembling the hub 831 and the mandrel 832 which have been integrally formed in advance, and the mandrel and components such as the housing and the stator base must be clamped. After the assembly is completed (not shown), the hub 831 can be assembled to one end of the mandrel in an assembled manner.

For example, referring to FIG. 2, a conventional motor rotating member 9 in which a "hub" and a "mandrel" are not combined by an integral injection molding method is disclosed. The conventional rotating member 9 includes a hub 91. A mandrel 92 and a holding member 93. The hub 91 is provided with a through hole 911. The inner wall of the hole 911 defines a face 912 and a first protrusion 913. The outer periphery of the mandrel 92 is provided with a slot 921, a plane 922 and a second protrusion 923. The mandrel 92 extends through the through hole 911 of the hub 91 so that the plane 922 and the cut surface 912 can abut each other, thereby preventing the spindle 92 from rotating relative to the hub 91. In addition, the second protruding surface The 923 also abuts the first protruding surface 913. After the fastening member 93 is coupled to the slot 921 of the spindle 92, the holding member 93 can be used to prevent the spindle 92 from coming off the hub 91.

The hub 91 of the above-mentioned conventional motor rotating member 9 is generally made of a plastic material. Since the characteristics of the plastic material are elastic and easy to wear, when the conventional motor rotating member 9 is combined with a permanent magnet (not shown) In order to construct a rotor (not shown) of a motor, the motor is rotated during the long-time driving of the motor rotating member 9, assuming that the conventional rotating member 9 abuts only by the cut surface 912 formed by the hub 91. The plane 922 of the mandrel 92 does not effectively prevent the mandrel 92 from rotating relative to the hub 91. Moreover, after the motor rotating member 9 is rotated for a long time, the plane 922 and the section 912 are easy to each other. The wear is generated to generate a gap, so that the mandrel 92 is easily loosened in the through hole 911 of the hub 91. In addition to the inability to effectively prevent the mandrel 92 from rotating relative to the hub 91, problems such as noise are more likely to occur. Caused a lot of inconvenience in use.

The inner hole wall of the through hole 52 extends through a plurality of elastic buckles 53 for allowing the mandrel 2 to pass through. Each of the elastic cleats 53 has a distal end 531 extending into the slot 23 of the mandrel 2 so that the fixing piece 5 can be surely coupled to the mandrel 2, thereby preventing the mandrel 2 from being detached by the fixing piece 5. The hub 1.

More specifically, when the stopper portion 24 is formed on a plane of the outer peripheral surface of the mandrel 2, the abutting portion 51 of the fixing piece 5 may be formed on the inner wall of the through hole 52. The side 511 abuts the plane formed by the stop portion 24 to prevent the spindle 2 from rotating relative to the hub 1. In addition, as shown in FIG. 16, in the axial direction of the mandrel 2, the end 531 of each of the elastic clasps 53 and the trimming edge 511 formed by the abutting portion 51 have a height difference (h) for the fixing. When the end 531 of each of the elastic clasps 53 of the sheet 5 projects into the slot 23 of the spindle 2, the abutment portion 51 of the fixing piece 5 can surely abut the stopper portion 24.

The main feature of the motor rotating member according to the second embodiment of the present invention is that the fixing piece 5 can be further prevented from being effectively prevented by the fixing piece 5 under the premise that the fixing piece 5 is actually positioned on the assembling portion 12 of the hub 1. 2 rotating relative to the hub 1; more importantly, since the fixing piece 5 also has a function of preventing the spindle 2 from coming off the hub 1, the motor rotating member of the second embodiment of the present invention can be omitted as in the first embodiment The disclosed fastener 3 has a relatively reduced component composition and can reduce the overall structural complexity. In addition, the structural design of the fixing piece 5 of the motor rotating member and the hub 1 of the second embodiment of the present invention can be appropriately selected according to the actual needs, as disclosed in the foregoing Figures 3 to 14, which are in the technical field. Those who have the usual knowledge can implement it, and will not be described in detail here.

It is known that the motor rotating member of the present invention can effectively prevent the spindle 2 from rotating relative to the hub 1 by using the fixing pieces 4, 5; therefore, the motor rotating member of the present invention has various motor structures when applied to various motor structures. The structure is simple and can improve the operation quality and many other functions.
