Abstract
The present invention provides a vibration motor including stator, comprising a brush and a rotor which includes casing, magnet and bearing, wherein the bearing is made by die casting from resin material, the casing and the magnet are secured with the bearing by integration with the resin material through inserting die assembly in the die casting process. By applying the invention, the assembling steps of vibration motor and the number of components are reduced, thus the manufacturing cost is lowered.
Description
Invention field
The present invention relates to a kind of vibrating motor, particularly in the communication equipment such as mobile phone, beeper, be used for when signal comes, producing vibration to remind user's vibrating motor.
Background technology
Fig. 3 is the profile of prior art vibrating motor.As shown in Figure 3, stator 105 is made of shell 101, magnetite 102, magnetite cover 103 and oilless bearing 104, thereby rotor 107 inserts brush station 106 successively and stator 105 is formed complete vibrating motor 100, and wherein magnetite is made up of cobalt samarium (SmCo).
In above-mentioned vibrating motor, the assembling process of stator 105 is as follows, and at first, because magnetite 102 is sinter moldings, the physical dimension deviation is bigger, therefore need carry out shaping processing to be fit to the size of magnetite cover 103 to magnetite internal diameter and end face.Subsequently, magnetite 102 is fixed in the magnetite cover 103 and carries out destressing and handle to discharge gas.The magnetite cover 103 of putting into magnetite 102 is pressed into shell 101 subsequently, oilless bearing 104 is embedded at last again, finishes the assembling of stator thus.Therefore this vibrating motor need carry out shaping processing and destressing treatment step to magnetite, and amount of parts is also more, thereby has the higher shortcoming of manufacturing cost.
Summary of the invention
Therefore the purpose of this invention is to provide a kind of vibrating motor, thereby it can reduce the stator assembly process and number of components and parts reduces manufacturing cost.
According to vibrating motor of the present invention, comprise stator, brush station parts and the eccentric rotor that divides copper is installed, described stator comprises shell, magnetite and bearing, wherein, described bearing is made by the resin material injection molding, thereby and described shell and magnetite by in injection molded process, inserting mould and the one-body molded and described bearing fixing of resin material is in the same place.
Because bearing adopts resin material to make, shell and magnetite and bearing integrated molding, thus reduced vibrating motor assembly process and number of components and parts, thus manufacturing cost reduced.
Description of drawings
Fig. 1 is the profile according to vibrating motor of the present invention;
Fig. 2 is the profile according to the stator of vibrating motor of the present invention; And
Fig. 3 is the profile of prior art vibrating motor.
The concrete mode that carries out an invention
Below describe this inventive embodiment in detail by accompanying drawing.
Vibrating motor 1 shown in Figure 1 is made of stator 5, brush station parts 8 and rotor 14.Stator 5 is made of shell 2, magnetite 3, resin bearing 4, and brush station parts 8 are made of brush station 6 and brush 7, and rotor 14 is made of commutator 9, coil 10, commutator components 11, rotating shaft 12 and the eccentric copper 13 that divides.When mobile phone receives calling, produce electric current and flow into coil 10 through brush 7 and commutator 9, the coil 10 of energising and the electromagnetic force between the magnetite 3 make rotor 14 rotate, owing to be fixed on the effect that the off-centre in the rotating shaft 12 is divided copper 13, vibrating motor 1 will begin vibration to notify the user to have the people to call out.
The shell 2 of stator 5 is for made of iron and be cylindric, and it is cylindric that magnetite 3 also is, and bearing is made by the resin material injection molding, thereby and described shell be in the same place by insertion mould and the one-body molded and described bearing fixing of resin material in injection molded process with magnetite.As shown in Figure 2, the resin bearing 4 of stator 5 has the inserting hole 15 that can insert rotating shaft 12, this inserting hole 15 is positioned at the opposite side of eccentric branch copper 13 and comprises brearing bore 16 and grease storage position 17, and rotating shaft 12 is sandwiched in brearing bore 16 and brush station 6 rotates between the two.The resin material of making bearing can adopt thermoplastic resin (PPS etc.) material, because the intensity of PPS and so on material is higher and the moving property of Zhe is fine, so compare with the oilless bearing that prior art is adopted, it has moving property of better Zhe and useful life.
The assembling process of the vibrating motor with above-mentioned structure is below described.
It at first is the assembling process of stator.In the prior art, magnetite 3 is that sintering forms, dimensional discrepancy is bigger, therefore just can be fixed on the magnetite cover 103 after need processing the internal diameter of magnetite 3 and end face, but in the present invention, owing to adopted the resin and plastic molding process to make bearing, thereby shell 2 and magnetite 3 can be by inserting mould and the one-body molded and described bearing fixing of resin material together in injection molded process, so omitted behind the magnetite sintering operation that shaping is again processed.Secondly, rotating shaft 12 is pressed into commutator 11, installs coil 10, and such rotating shaft 12 is inserted in the brush station 6 of brush station parts 8, insert then in the in type stator 5.At last, off-centre is divided a end that copper 13 are combined in rotating shaft 12 and with the tail end of brush station parts 8 riveteds at motor.In above-mentioned assembling process, all apply lubricant grease in inserting hole 15, brearing bore 16 and the rotating shaft 12.
Claims (3)
1. vibrating motor, comprise stator, brush station parts and the eccentric rotor that divides copper is installed, described stator comprises shell, magnetite and bearing, it is characterized in that, described bearing is made by the resin material injection molding, thereby and described shell and magnetite by in injection molded process, inserting mould and the one-body molded and described bearing fixing of resin material is in the same place.
2. vibrating motor as claimed in claim 1 is characterized in that, described resin material is the thermoplastic resin material.
3. vibrating motor as claimed in claim 1 or 2 is characterized in that described bearing comprises the inserting hole that can insert rotating shaft, and this inserting hole comprises brearing bore and grease storage position.
