New description: [New technical field] This is a motor assembly and buckle. [Prior Art] The motor uses the principle of electromagnetic effect to convert electrical energy into mechanical energy, and has been widely used in mechanical structures such as wind shoulders, CD players or hard disk drives. In general, the motor includes a rotor and a stator that drives the rotor to rotate relative to the stator by magnetic interaction between the rotor and the stator. Wherein, the rotor has a rotating shaft, and the rotating shaft is threaded through the bearing and supported by the bearing. The motor further includes a buckle that is snapped into the groove of the rotating shaft and abuts against the bearing to limit the axial movement caused by the rotation of the rotor. However, conventional buckles have some problems in assembly. The buckles can be divided into axial installation and radial installation according to different installation methods. Referring to FIG. 1 , a conventional axially mounted buckle 14 is a c-shaped ring, which mainly includes a through hole 141 and a crack 142. The through hole 141 is used for arranging a rotating shaft, and the crack I42 can help the through hole M1. Open to set the shaft. However, since the perforations 141 are rounded, the buckle 14 is not easily aligned with the axis of the shaft, thereby increasing the time required for installation. Further, the structure of the buckle 14 is monotonous, the structural strength thereof is small, and the stress is easily concentrated at a point, so that if an erroneous action, such as pulling, occurs in the case of a security, it is liable to cause damage. In addition, the buckle 14 is not easily disassembled after installation because it has no force application point. Therefore, how to provide a motor assembly and a buckle, which can easily align the rotating shaft and avoid stress concentration, thereby shortening the installation time and improving the yield, is one of the current important courses M335089. [New content] In view of the above problems, the purpose of the present invention is to provide a motor assembly and a buckle that can be easily aligned with a rotating shaft and avoid stress concentration. The reason is that, for the above purpose, the buckle of the present invention is mounted on a rotating shaft. The buckle includes a plurality of first fixing portions, a second fixing portion, and a plurality of buffer portions. The inner edges of the first fixing portion and the second fixing portion are formed in a perforation manner, and the sleeves are provided between the fixing portions and the fixing portions. A crack is connected to the perforation to assist the floor to open the perforation. The buffer portion is disposed between the first fixed portion and the second portion. :,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The shaft is threaded with bearings. The buckle ring is axially mounted on the rotating shaft, and has a plurality of eyelids, a plurality of second fixing portions, and a plurality of buffer portions. - the fixed portion and the second fixed portion are discontinuously formed - perforated, and the first: there is a crack between the fixed portions and the first step and the second are set with the opening of the 'hole' Between the departments. In accordance with the above-mentioned 'invented by the county-type motor components and buckles, the coefficient of the fixed part of the discontinuous ancient, hard, and style forming a perforated set of rotating shaft, and thus convenient alignment, ^ Bu, buffer The system is disposed between the two fixing portions to absorb the inside and avoid the stress pin to be buckled _ bad to improve the yield. [Embodiment] M335089 A motor and a buckle according to a preferred embodiment of the present invention will be described below with reference to the related drawings. - Month-seeking Fig. 2' Fig. 2 is a schematic view showing the combination of the buckle and the rotating shaft of the motor assembly of the present invention. The motor assembly 2 of the preferred embodiment of the present invention includes a bearing sleeve 21, a car spring 2 shaft 23 and a buckle core 24. The motor assembly 2 of the present embodiment can be applied to an inner rotor motor or an outer rotor motor. Spindle 23 series? A bearing 22 is provided and supported by the bearing 22. The shaft 23 has a groove 23, and the buckle ring 24 is axially mounted to the groove of the shaft 23. FIG. 3 is a schematic view of the buckle of FIG. 2. The buckle 24 of the embodiment has a plurality of first fixing portions n and F2, a plurality of second fixing portions Η, F4, and a plurality of buffer portions. B1 to B3 'f - the fixed portion 打, which is symmetrically arranged and has two phases of the phase two, and the first fixed portion is symmetrically arranged and has the same structure, and the & 卩PI F7 and the first solid portion The inner edge of the F4 is discontinuously formed - the second shaft is sleeved. In the present embodiment, since the inner edges of the first fixed portion F1 and the second fixed portion are curved, an inner shape is formed. ^23 _ ° of the discontinuous circle and 'outside the first _ Π, F2, = 晴 晴 晴 晴 晴 晴 晴 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且The structure also has the stress of distracting the assembly.

When the LH is installed for the first fixed part buckle 24, the .=, _ right is not _ shape, so it is assisted in the inner edge of the M335089 of the second fixed part F3, F4 4A. When buckled After the ring 24 is aligned with the rotating shaft 23 and then pressed down, the perforation H of the buckle 24 will be approximately extended to allow the rotating shaft 23 to enter the perforation. Finally, when the buckle % 24 is moved to the groove 231 of the rotating shaft 23, the buckle is buckled. The ring is restored to the original shaft, and is fixed to the rotating shaft 23, as shown in Fig. 2 and Fig. 4B. The cushioning portion to the B3 are respectively disposed between the first fixing portion FbF2 and the second fixing portions F3 and F4. In each of the buffer portions B1 to B3, a notch Q1 to 03 notch 〇i to 〇3 are connected to the through hole H, and the openings (1) to (7) are not limited to each other as shown in Fig. 3. In this embodiment, For example, the buffer portion Bi~ is in the shape of an arm. The buffer portions B1 to B3 and the notches 〇1 to 〇3 can form a buffer structure when the buckle 24 is mounted to absorb and disperse the force, thereby avoiding stress concentration and causing the buckle 24 to be deformed. In addition, the second fixing portions F3, F4 have a crack 243. The crack 243 is in communication with the through hole H, so the crack 243 can help the perforating raft to open to fit the rotating shaft 23. In the embodiment, the crack 243 It is disposed opposite to a buffer portion 。 1. In addition, the buckle 24 further includes at least a detaching port 244, which is coupled to The fixed portion F3 and the slit 243 are connected. The detaching port 244 is useful for disassembling the buckle after the installation is completed. It is worth mentioning that the detaching port does not need to be connected with the crack, as shown in Fig. 5, which shows the buckle 24a. There are a plurality of detaching mouths, 246, which are disposed on two sides of the crack 243, but the position of the detaching port is not limited to the position shown in the figure, which is easy to disassemble after assembly as a main consideration. According to the creation of the shaft and the buckle, the plurality of first and second jaws are formed in a discontinuous manner to form a perforated sleeve, thereby facilitating the M335089 to rotate the shaft and shorten the installation time. In addition, the absorption of strength, the role of stress needles and smuggling; between the Ministry of 忾 = ship complex, turn __. Any spirit that has not been created and (4), (4) its grain modifications shall be included in the scope of the patent application attached.
