The bearing housing η and the cover 12 are closed by a plurality of staking structures 13 to be closed. However, since the vehicle 曰 motor ι needs to use a set of punching jigs to join the bearing housing 11 and the cover 12 with the staking structure 13, the production cost is increased. D In addition to the above-mentioned conventional vehicle motor, it can also be locked by a cover having a plurality of screw holes and a bearing housing and through a plurality of screws (not shown). However, this method not only increases the assembly. The time required, and the life of the locking components (such as screws) also affect the life of the product. Therefore, 'how to provide a motor and its housing, which can ensure good sealing without using additional fixtures and locking components, thus reducing production costs, shortening production time and extending product life cycle, before 1353100 One of the important items [Explanation] In view of the above problems, an object of the present invention is to provide an excellent jig and a lock member, that is, to ensure a good fit and a casing thereof. The horse edge is 'for the above purpose, the system according to the invention comprises - the bearing housing and the -n". The motor of the motor and the cover. The circumference of the bearing housing has a wide interface - the interface portion. The peripheral edge has at least one second connection corresponding to the first joint portion. The bearing seat disk σβ square a, #笛也 " > degree /, Zhuo Yu is by relative displacement, so that the first joint and the second joint The joint connecting seat is in close contact with the cover.吏^ bearing 2 For the above purpose, a motor system according to the invention comprises a motor body and a housing. The housing is covered and secured to include a bearing housing and a cover. The circumference of the bearing housing has at least an engagement portion. The periphery of the cover has at least one second engaging portion corresponding to the first engaging portion. The bearing housing and the cover are coupled to the second engaging portion by relative displacement/method so that the bearing housing is in close contact with the 1 cover. According to the invention, in the motor and the housing thereof, the bearing housing and the cover of the force-receiving housing are coupled to each other by a correspondingly disposed joint portion. Compared with the prior art, the present invention does not require an additional fixture and a locking component to ensure good sealing, and the sweating reduces the production cost and shortens the production time, and prolongs the use of the product along the 1353100 period. [Embodiment] Hereinafter, a motor and a casing thereof according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, and the same components will be described with the same reference numerals.

After the closing, the first engaging portion 211 and the second engaging portion 221 are coupled in a fitting or engaging manner and provide axial and circumferential restraint between the bearing housing 31 and the cover 32. Further, in order to increase the joint strength, an adhesive may be applied between the first joining portion 211 and the second joining portion 221. Therefore, a barb (not shown) may be disposed at an end of the second joint portion 221 (ie, the flange), and the first joint portion 211 (ie, the groove) is provided with a limit portion (not shown). Corresponding to this barb, it is more able to increase the strength of the link. In this embodiment, the second engaging portion 221 is disposed on the inner circumference and the edge of the cover 22, and the first engaging portion 211 is disposed on the bearing housing μ corresponding to the second engaging portion 221 In the right place. Referring to FIG. 3A, a housing 30 for a vehicular motor according to a second embodiment of the present invention includes a bearing housing 31 and a cover 1353100. 32. The socket 31 has at least a joint portion 3ΐ. The two 'covers 32 are provided with at least one second joint portion 321 ^ < 3 11 with a groove as an example, for example. The first joint portion 321 has a flange as a two-in-one joint portion 311 and a second joint portion 321 by (4) being aligned with each other with the m 321 aligned with the bearing block 31. First: the first-connected "p seedling 312 axial combination Then, the cover is rotated relative to the bearing housing 31. The second engaging portion 321 is screwed into the first position to limit the axial direction of the bearing housing 31 and the cover 3. The bite is provided for further step-by-step reinforcement. The limit ensures that the joint is not displaced by the cover ” "the bearing block 31 is rotated relative to the circumference so that the second joint (2) is released from the port 312. Referring to Fig. 3, a partial enlarged view of the line 311 connected to the second joint portion 321 is shown. The second s milk system has a - card point ρ, and the first engaging portion 311 is provided with a card slot R'. The card point P is snapped into and fits into the card slot R. The structure of the card point p and the card slot R can provide a circumferential limit of the cover 32 and the bearing housing 31. In addition, in order to increase the joint strength, the first joint portion 3" and the second joint portion 32 may be joined by adhesive means. Of course, as shown in FIG. 3C, the click point P may be disposed on the first joint portion 3U, and The card slot is disposed on the second joint portion 32 h. The casing of the vehicle motor of the third embodiment is shown in Fig. 4. Another 1353100 body 40 of the present invention and the above embodiment 421 U are in the cover 42. The second joint portion is a plurality of discontinuous grooves, and the shackle bearing housing 41 is provided with a plurality of discontinuous first grooves 41 at the corresponding Zhoutian position. 411 (such as the flange). The ridges and the outer periphery of the shroud 2 are disposed on the bearing housing 41. The ridges and the recesses 421 are located opposite each other when the cover a and the bearing are assembled, and the first joint portion 411 and the stem are similar to the TMX The relative position of a joint portion 421 is aligned, and the axial force is applied to the pressure of the cover 42 and the bearing block 41 to generate an axial relative displacement. Further, the cover 42 and the bearing housing 41 are coupled; when the diameter of 4! is smaller than the cover 42, the groove on the cover 42 can be provided with the inner circumference of the cover 42. The flange of the bearing housing 41 is disposed on the bearing housing 41 corresponding to the recess. In summary, according to the motor and the casing thereof of the present invention, the bearing housing and the cover constituting the installation body are coupled to each other in a relative displacement manner by correspondingly disposed joint portions. Compared with the prior art, the present invention can ensure good sealing without using additional jigs and locking elements, thereby reducing production costs and shortening the production time period and extending the service life of the product. The above is intended to be illustrative only and not limiting. Any changes or modifications to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
