Description

A kind of novel mobile phone shaking device

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,

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 end cap 1 effect is that power delivery with the outside is to brush body 2.Rotary body 200 is mobiles, and commutator segment 3 is installed in the center ledge 4-1 of whole commutator 4 and links together with plastic commutator 4-2 and eccentric wheel 5 parts in the rotary body 200, and eccentric wheel 5 is to produce vibrations when utilizing eccentric centrifugal force rotation.Eccentric wheel 5 cores are provided with the hole 5-3 that is connected usefulness with axle 6, the side of eccentric wheel 5 and commutator plastic cement 4 formation assembly 4-3, and a side of eccentric wheel 5 has groove 5-2, and the lower end of eccentric wheel 5 is provided with the groove 5-1 that is connected with coil 7.Magnet steel 11 is enclosed within the outside of rigid bearing chamber 10 in the motor fixed body 300, and rigid bearing chamber 10 is fixed on the lower end of housing 12, and bearing 9 is arranged on the inwall of rigid bearing chamber 10, and pad 8 is arranged on the upper end of bearing 9.

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.
