Description of the Invention: [Technical Field] The present invention relates to a frame of a motor, and more particularly to a base structure of a motor frame formed by a plastic-tube-body-gold-view plate. Technology] The conventional motor frame is generally composed of a base and a frame. It is known that the motor frame can be combined with components such as a stator and a rotor to form a motor structure. In general, the base and the frame of the conventional motor frame can be formed by material-body injection molding, but the overall structure of the motor frame is ploughed by plastic riding materials, which has problems such as poor structural strength. Moreover, in order to improve the problems arising from the aforementioned motor frame made of plastic material, it is also known in the market that the overall structure of the motor frame is made of metal material-body forming to increase the heat dissipation effect, or It is also known that the motor frame is made of a plastic material having a lower price, and the base is made of a metal material in order to maintain a certain structural strength and have a better scatter. Therefore, if the structural strength and heat dissipation effect of the conventional motor frame are taken as a precondition, it is preferable to use a base made of a metal material as a priority. Referring to Fig. 1, the base 9 of a conventional motor frame made of a metal material is described as an example. The base 9 includes a bottom plate 91 and a shaft tube 92. The bottom plate 91 is made of a metal material, and has a connecting portion 911 at the center of the bottom plate 91. The shaft tube 92 has a first end 921 and a second end 922. The first end 921 and the second end The 922 is open. When the assembly is actually performed, the first end 921 of the shaft tube 92 is assembled to the socket portion 911 of the bottom plate 91, and the first end 921 must be closed by a cover (not shown). Thereby, the bottom plate 91 can be combined with a frame (not shown) to constitute a conventional motor frame structure. The base 9 of the conventional motor frame made of the above-mentioned metal material can provide better structural strength after the motor frame structure is constructed, but has the following disadvantages in practical use: 1. The joint stability is not good: the shaft The tube 92 is usually assembled to the sleeve portion 911 of the bottom plate 91 in a tight fit manner, but the sleeve portion 911 of the bottom plate 91 is easily deformed by factors such as thermal expansion and contraction during long-term use, resulting in the shaft. The tube 92 cannot be firmly fitted into the socket portion 911 'causing the shaft tube 92 to loosen from the bottom plate 91. 2. Poor assembly convenience: the assembly mode of the bottom plate 91 and the shaft tube 92 is mainly to fit the shaft tube 92 tightly on the bottom plate 91. Since the assembly process, the first part of the shaft tube 92 must be considered. The assembly alignment relationship between the end 921 and the sleeve portion 911 of the bottom plate 91 thus causes a lot of inconvenience in assembly; further, after the assembly work of the shaft tube 92 is completed, the closure member must be additionally utilized ( The first end portion 21 is closed, so that the assembly step is too complicated and complicated. 3. The verticality of the shaft tube is not good: when the sleeve portion 9 of the bottom plate 91 or the first end 921 of the shaft member 92 is assembled and dimensionally produced after the manufacturing is completed, the shaft tube 92 is assembled to the sleeve of the bottom plate 91. When the joint portion 911 is used, in addition to the problems such as the front secret and the inconvenient assembly, the verticality of the shaft tube 92 relative to the horizontal plane of the bottom plate 91 may not be in conformity with the standard 'so' when the base 9 is combined with the stator And the composition of the rotor and other components - the motor structure - also easily affect the product quality of the motor. SUMMARY OF THE INVENTION The present invention is directed to a base of a motor frame, which can be modified to cover a conventional motor frame made of a metal material, which has poor combination stability, poor assembly convenience, and vertical axis of the shaft tube. Many shortcomings such as Jia are the main purpose of the invention. The base of the motor frame comprises a bottom plate and a shaft tube. The bottom plate is a metal plate. The bottom plate has a fixing area in the center, and the fixing area includes a perforation and a joint portion, wherein the fixing area is outside the perforation The joint portion is the joint portion; the shaft tube is a plastic tube body with an empty space, the shaft tube is - the town-made end, the other end is formed - the open end, and the closed end of the shaft tube is coupled to the bottom plate a fixed area, and the closed end closes the through hole and covers the joint. In this way, it can achieve many functions such as increasing the stability of the combination, facilitating the assembly, and improving the quality of the product. The closed end is divided into a first covering portion and a second covering portion. The first covering portion and the second covering portion jointly hold the joint portion of the bottom plate. By this, the progress of the joint between the shaft tube and the bottom plate is improved. il,, > 〇 s. The cymbal includes a plurality of tabs formed on the inner side of the hole of the perforation, and a joint circumference surrounding and adjacent to the perforation, one end of each of the tabs extending horizontally in a control direction toward a center of the perforation; and the closed end Preferably, the second cladding portion and the second cladding portion may cover each of the protrusions and the bonding periphery.

In the present embodiment, only the simple structural design of the perforation 72 is used, and it is not necessary to use the members such as the inclined piece 13 or the extending piece 531 of the foregoing various examples, so as to be the second And the third real-time lifting combined area and preventing the axis: 80 arbitrary rotation and other recorded points, so that the function of the (four) structure is further designed by the recessed portion 74 of the bottom plate 70, the second covering portion 812 can be Buried in the recessed portion 74 N, and the overall axial height is also effectively reduced. - As described above, by the structural design of the & seats 1, 2, 3, 4 of the motor frame of the above embodiments of the present invention, the present invention is mainly applied to the shaft tubes 2, 4, and 6G made of plastic material. In the process of injection molding, the 8G can cover the predetermined portions of the bottom plates 1G, 30, 5G, and 7G at the same time to constitute the structure of the bases 1, 2, 3, and 4. Therefore, the present invention can achieve the following effects. : '1. Increasing the combination stability: Since the shaft tube 20, 40, 60, 8Q is covered by the _ end 21 U, 6 卜 81 body, the joint portion of the bottom plate 1 %, %, 50, 70 π 33, 53, 73, therefore, the shaft tubes 2〇, 4〇, 60, 80 can be firmly coupled to the bottom plates 1〇, 3〇, 5〇, 7〇 without arbitrarily falling off. 2. Good assembly convenience: the bottom plates 10, 30, 50., 70 of the present invention are combined with the various embodiments of the joints 13, 33, 53, 73 of the bottom plates 10, 3, 5, and 7 The manner in which the shaft tubes 20, 40, 60, and 80 are coupled to each other is mainly to integrally mold the ribs of the shaft tubes 2, 4, and 4, and also to cover the joint portions π, 33, and 53, 73. Therefore, in the overall assembly process, it is not necessary to consider the assembly alignment relationship between the shaft portions 20, 40, 60, 80 and the joint portions 13, 33, 53, 73 of the bottom plates 10, 30, 50, 70. Moreover, when the shaft ends 2, 40, 60, 80 form the closed ends 21, 41, 61, 81, 'the perforations 12, 32, 52, 72 can be closed at the same time', so that the assembly work can be effectively reduced.
