Abstract
A novel vibration device for a mobile phone relates to the improvement of communication equipment, in particular to the improvement of the mobile phone. A machine shell fixing body (300) consists of a gasket (8), a bearing (9), an injection-molding bearing chamber (10), a magnetic steel (11) and a machine shell (12); an injection-molding piece of the fixing electric brush body (2) of an end cover (1) is inserted towards the inside of the machine shell (12); a commutator segment of a rotator is arranged on the central projecting part of a commutator and is partially connected with the plastic commutator and an eccentric wheel. In the utility model, the eccentric wheel of a vibrating motor is arranged inside the machine shell, so that the whole volume of the product is reduced and the communication equipment develops towards the trend of miniaturization, simultaneously the phenomenon, such as poor contact, falling off of the eccentric wheel, damage of the communication parts, and the like, will not happen.
Description
Technical field:
The utility model relates to a kind of improvement of communication apparatus, is specifically related to a kind of improvement of mobile phone.
Background technology:
The vibrations of mobile phone are a kind of common alerting patterns, and advantages such as, noiselessness effective owing to reminding are subjected to numerous users' welcome.The centrifugal shaking force that produces when the most employing of mobile phone shaking device eccentric wheel rotates on the existing market produces vibrating effect, the concrete course of work such as Fig. 1, shown in Figure 2, existing vibrating motor axle 25 combines with commutator plastic cement 24, commutator plastic cement 24 peripheries are pasted with coil 26, and the commutator segment 23 on coil 26 and commutator plastic cement 24 tops is welded together to form power supply and enters into the magnetic line of force that coil 26 produces magnetic force and magnet steel 28 by commutator segment 23 and form mutual motive force and form the motor rotation and finally reach rotation and stick on axle 25 other end eccentric wheels 33 and produce an effect that shakes.Its eccentric wheel 33 of such drive motor sticks on the inside that axle 25 other end casings 31 outsides are installed in communication equipment and other utensil; Install that the back produces friction with other parts easily or produce to collide when this type of vibrating motor and cause the vibrating motor cisco unity malfunction, other parts above the also easy defective communication equipment with other parts; Another shortcoming to be eccentric wheel 33 in the motor outside cause space hold area is bigger and influence the miniaturization development of whole communication equipment, also take place easily eccentric wheel at work with axle 25 disengagings.Existing these motors all are to have adopted casing 31 and stainless steel or copper bearing chamber 30, magnet steel 28, bearing 29,32 to combine, make up these parts and all need to use in a large number glue, adopt the many processing steps of glue combination not only on production technology, having increased, also the qualification rate that causes product descends because glue combination back itself comes off easily, has increased production cost.
The utility model content:
The purpose of this utility model provides a kind of novel mobile phone shaking device, it is installed in casing inside with the eccentric wheel of vibrating motor, the feasible overall volume miniaturization more that changes its product, make communication apparatus be easy to more to miniaturization development, and can not produce loose contact, eccentric wheel comes off, damages phenomenons such as communication component.In order to solve the existing problem of background technology, the utility model is by the following technical solutions: vibrating motor is made up of brush 100, rotary body 200, casing fixture 300,
The utility model is installed in the inside of casing 12 with eccentric wheel 5, has made things convenient for the miniaturization of communication apparatus to improve, meet the developing direction of communication apparatus, has reduced shaking device shared space in communication apparatus.Because eccentric wheel and commutator plastic cement are integral, simplified production technology, also make the more stable quality of product, improved the impact resistance of product, also make eccentric wheel in the high speed rotating process, can not come off, can not make that the part of communication apparatus inside is damaged yet, thus the whole stability of influence.Also save, glue makes up this very complicated and unsettled technology, has reduced the production cost of glue combination, has improved stability.

Fig. 1, Fig. 2 are prior art constructions schematic diagrames in the background technology, Fig. 3 is a decomposition texture schematic diagram of the present utility model, Fig. 4 is the cutaway view after the utility model assembling, Fig. 5 a is the decomposition texture schematic diagram of rotary body 200, Fig. 5 b is the structural representation of rotary body 200, Fig. 6 is the structural representation of casing fixed body 300, and Fig. 7 is the cutaway view of another section of the utility model.
Embodiment:
Shown in Fig. 3-7, this embodiment by the following technical solutions: vibrating motor is made up of brush 100, rotary body 200, casing fixture 300, and brush 100 is made up of end cap 1, brush body 2; Rotary body 200 is made up of commutator segment 3, commutator plastic cement 4, eccentric wheel 5, axle 6, coil 7; Casing fixed body 300 is made up of pad 8, bearing 9, injection moulding bearing chamber 10, magnet steel 11 and casing 12; The moulding of the fixed brush body 2 of end cap 1 inserts to the inside of casing 12, and effect is that power delivery with the outside is to brush body 2.
Periphery two sections semi-circular processing of formation of eccentric wheel 5 its objective is after being injection molded into circle at little semi-circular portions another side is inserted in coil 7.The main effect of large semicircle part is commutator plastic cement 4 and eccentric wheel to be closely linked commutator comes off when preventing to rotate; Another effect is when preventing that rotary impact power is big, and the distortion that prevents the brush on center fixation body and the end cap 1 causes the damage of motor.
Rigid bearing chamber 10, bearing 9, magnet steel 11, casing 12 adopt injection molding way to be combined as a whole in the motor fixed body 300, just bearing 9, magnet steel 11, casing 12 are put into single injection-molded rigid bearing chamber 10 behind the position of fixing on the mould separately, injected plastics material is generally selected PBT (G30) environment-friendly materials for use.Bearing 9 is to adopt materials such as aluminium, lead, iron to be immersed in press molding in the lubricant (being oiliness bearing), need not to add products such as lubricant.Magnet steel 11 is combined in the periphery of rigid bearing chamber 10, and bearing 9 is inserted in the upper end of rigid bearing chamber, and casing 12 utilizes injection moulding to be fixed on the end portion of rigid bearing chamber 10.Casing 12 outsides have put rubber sleeve 13,15 in order to combine closely with wiring board in the periphery.This embodiment has been simplified the course of work, got rid of because the various quality problems that glue too much causes have also reduced production cost, improved production efficiency, also made eccentric wheel can not come off, even can not come off when being subjected to powerful impulsive force yet, prolong the useful life of product.
