Description
Technical field
The invention belongs to there is the motor technology field of magnet, armature or coil system reciprocal, be oscillated or vibrated, specifically
Disclose a kind of micro motor of casing automatic buckling.
Background technique
Vibrating motor is primarily referred to as the vibrating motor for mobile phone, belongs to brush direct current motor.Micro-vibration
Motor is usually assembled by upper casing and lower casing, and the prior art is when assembling upper casing and lower casing, usually
It is assembled by the way of pressing, such mode is by blocking upper casing and lower casing edge by force under ambient pressure
Be combined, form interference fit, to realize the fixation of upper casing and lower casing, but due to vibrating motor volume compared with
It is small, therefore when being pressed, upper casing and lower casing edge are easy to produce deformation under external force, and then lead to upper casing
It is damaged with lower casing, yields is caused to reduce.
Summary of the invention
The invention discloses a kind of micro motors of casing automatic buckling, logical it is an object of the invention to solve the prior art
The problem of crossing the mode to press to assemble upper casing and lower casing, upper casing and lower casing be easy to cause to damage.
Base case of the invention are as follows: the micro motor of casing automatic buckling, including upper casing, lower casing, rotor, upper machine

Through-hole is provided with sliding slot on support column side wall, voussoir is slidably fitted in sliding slot, and elastic component is equipped between voussoir and sliding slot.
Technical principle and beneficial effect of the invention is: when assembling to upper casing and lower casing, it is only necessary to will
Support column alignment through-hole is simultaneously downwardly into, during support column passes through through-hole, voussoir and through-hole EDGE CONTACT, and by
To the reaction force from through-hole edge, so that voussoir is slided into sliding slot, and then overcomes the elastic force of elastic component and slide into sliding slot
It is interior, when voussoir pass through through-hole after, elastic component elastic force effect under, voussoir is popped up out of sliding slot so that voussoir upper surface with it is convex
Edge lower end surface offsets, and realizes the fixation between upper casing and lower casing.Compared to the prior art using by riveting by the way of
Assembly fixation is carried out to upper casing and lower casing, the invention avoids cause upper casing and lower casing to generate shape during riveting
The case where becoming and damaging has higher yields.
Further, rotor is in cam-like.Compared to rounded but non-uniform mass rotor is used, the present invention is used
Cam-like rotor makes the mass centre of rotor deviate center of rotation, so that center of gravity constantly changes rotor during rotation
Become, generates vibration.

It is provided with third blind hole and the 4th blind hole, the first slide bar and the second the lower end of the slider face are provided with fluid hole, are injected with A in the first blind hole
Glue is injected with B glue in the second blind hole.By above-mentioned design, it during motor is fixedly installed on circuit board, presses downwards
Pressure motor, so that the first slide bar and the second slide bar be with respect to the first blind hole and the second blind hole upward sliding, so that the first blind hole
Reduce with the volume of the second blind hole, so that the B glue in the A glue and the second blind hole in the first blind hole passes through the first slide bar and the respectively
Fluid hole on two slide bars flows out on circuit board, so that A glue and the mixing of B glue, and then support column is adhered fixed in circuit board
On.It is fixed compared to the prior art using double-sided adhesive and foam, this embodiment avoids the vibrations of motor by flexible double
Face glue and foam are absorbed, and then strengthen the vibrating effect of motor.And since support rod props up motor, motor with
There are gaps between circuit board, further promote distributing for heat.
Further, limited block is additionally provided on the support column, the distance between limited block and voussoir are equal to the thickness of flange.
By above-mentioned design, so that voussoir upper surface and flange lower end surface offset while, limited block lower end surface and flange upper surface phase
It supports, further strengthens locating effect.
