Abstract
The utility model relates to a riveting structure between a micro-motor housing and a lower bracket, wherein a total of 2-6 flanged strips are provided at the circumference of the opening end of the housing in a uniform manner and the flanged strips are bent inward and pressed against the annular platform of the external circumference of the lower bracket. A bending portion of the riveting structure has a larger contact area and improves the coupling strength; less flanged strips can allow the control of deformation and displacement following a bending operation, thereby ensuring the bending accuracy for each flanged strip. The utility model has a relatively simple process and easy quality control with less quality control points.
Description
Technical field
The utility model relates to a kind of micro motor, particularly the riveted structure of a kind of casing of micro motor and bottom bracket.
Technical background
As a kind of micromachine that is mainly used on the small-sized electronic products such as mobile phone, beeper, electronic toy, the performance of aspects such as it is shock-resistant, anti-vibration is one of emphasis of paying close attention to of consumer, the casing thickness of micromachine is less, at present, the connected mode that casing and bottom bracket are comparatively commonly used is: several small embossments are set on casing, the ring-shaped platform on small embossment bending and the bottom bracket excircle is interlocked.The bonding strength of this connected mode, impact resistance can reach the purpose of design and the instructions for use of micro motor, the single projection of this syndeton is little, each protruding needed bending power is less, the bending power that is produced during bending is difficult for causing the casing distortion, in addition, the projection of a greater number also is easy to guarantee the axially loaded balance on the whole circumference; But, this syndeton belongs to a contact, in order to guarantee to be connected firmly with shock-resistant, for satisfying the bonding strength requirement of complete machine, small embossment need be set to more quantity, and according to the whole requirement of micro motor, deflection, the end deformation displacement after the bending of all projection all needs to keep the unanimity on the degree of precision, needing in the manufacture process just to have caused each small embossment of controlling based on the requirement on the precision, small embossment quantity is complicated more on many bendings technology more, quality is wayward more.
As mentioned above, there is following deficiency in prior art: the manufacturing process of casing and bottom bracket syndeton is comparatively complicated, quality is wayward.
Summary of the invention
The utility model has solved the casing of prior art existence and comparatively complicated, the uppity problem of quality of manufacturing process of bottom bracket syndeton, and a kind of riveted structure of casing and bottom bracket of micro motor is provided.A kind of casing of micro motor and the riveted structure of bottom bracket are that the circumference of casing openend is provided with 2-6 crimping band, are circumferentially at the casing openend evenly to distribute; The crimping band bends inwards, withholds on the ring-shaped platform of bottom bracket excircle.This riveted structure is compared to small embossment, and its bending part is long and contact area obtains increasing, and makes bonding strength big; The negligible amounts of crimping band, deflection, deformation displacement after being easy to guarantee to bend are easy to guarantee the bending precision of each crimping band, technology is comparatively simple, the minimizing of quality control position is easy to controlled thereby bend.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: as preferably, the circumference of described casing openend is provided with the crimping band; Described crimping band bends inwards, withholds on the ring-shaped platform of bottom bracket excircle.The crimping band structure makes the contact site of casing and bottom bracket strengthen, bigger bonding strength can be provided, make be connected firmly, shock-resistant, improve the whole shock resistance of micro motor simultaneously, and can make micro motor in use produce may being reduced of noise because of the minimizing of contact point.
As preferably, described crimping band is 2-6.Can provide separately optimal selection according to the different dimensions of a kind of micro motor.
As preferably, described crimping band circumferentially evenly distributes at the casing openend.Make that contact pressure is even, disperse.
As preferably, described crimping band and casing ontology are structure as a whole.Can adopt one-shot forming to make, reduce connecting link, strengthen reliability.
As preferably, the central angle of described crimping band is 30 °-120 °.Guarantee the enough circumferential lengths of crimping band.
Therefore, the utlity model has technology simple, be easy to control characteristics such as product quality.

Specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the circumference of casing 1 openend is provided with crimping band 9; Crimping band 9 is the integrative-structure that one-shot forming is made with casing ontology, and its quantity is 2-6, and the central angle that is surrounded is 30 °-120 °, circumferentially evenly distributes at casing 1 openend.
After in casing 1 inner chamber, installing assemblies such as stator, magnet steel, rotor 7, alignd with notch on casing 1 port in convex edge on bottom bracket 2 excircles, bottom bracket 2 is placed on the port of casing 1 openend, utilize riveting set that crimping band 9 bendings on casing 1 port to the ring-shaped platform with the excircle of bottom bracket 2 is joined again.
