Abstract
The present invention discloses an improved structure of a vibration motor rotor of a mobile phone, which comprises a printed-circuit board (PC board). One end of a center shaft of a rotor is sheathed with a shim, the printed-circuit board and a fixed ring in sequence, wherein the shim and the fixed ring are respectively fixed on the central shaft of the rotor and tightly press the PC board in an opposite direction, and in this way, the PC board and the central shaft are fixed mutually. Due to the fact that the fixed ring and a shim plate are fixed on the central shaft of the rotor and the PC board is arranged between the fixed ring and the shim plate, the PC board and the central shaft are fixed mutually. Therefore, the injection molding fixation is not needed, and the production cost can be substantially reduced. Moreover, the PC board can be matched with coils with various dimensions.
Description
Technical field
The present invention relates to a kind of rotor structure of mobile phone vibrating motor.
Background technology
Printed substrate (claiming the PC plate again) is fixed in rotor end-face, is used for the commutation of motor electrode; Referring to Fig. 1, printed substrate 10 is fixed in the centre of rotor axle in plastics 20 injection moulding modes at present, and cost is higher like this.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of structure of vibration motor rotor of mobile phone of improvement, this structure is easy to manufacture, and cost is lower, and can cooperate with the coil of multiple size.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of structure of vibration motor rotor of mobile phone of improvement, comprise printed substrate, the sheathed successively pad of centre of rotor axle one end, printed substrate (claiming the PC plate again), retainer plate, pad, retainer plate are individually fixed in the centre of rotor axle and press printed substrate in opposite directions, and the position of printed substrate and central shaft has just interfixed like this.
Pad dorsad on the central shaft of printed substrate one side fixed cover be provided with a plastic base plate, the diameter of plastic base plate is greater than the diameter of pad, further firm pad.
Pad is that copper product is made.
The invention has the beneficial effects as follows: because retainer plate and backing plate are fixed in the centre of rotor axle, the PC plate is located between retainer plate and the backing plate, and the position of PC plate and central shaft has just interfixed like this.Just do not need injection moulding to fix, can significantly reduce production costs, and can cooperate with the coil of multiple size.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is for commonly using mobile phone vibrating motor rotor portion structural representation;
Fig. 2 is a schematic diagram of the present invention.
Embodiment
Embodiment: referring to Fig. 2, a kind of structure of vibration motor rotor of mobile phone of improvement, comprise printed substrate (claiming the PC plate again), the sheathed successively pad 1 of centre of rotor axle one end, printed substrate 2, retainer plate 3, pad, retainer plate are individually fixed in the centre of rotor axle and press printed substrate in opposite directions, and the position of PC plate and central shaft has just interfixed like this.
Pad dorsad on the central shaft of PC plate one side fixed cover be provided with a plastic base plate 4, the diameter of plastic base plate 4 is greater than the diameter of pad, further firm pad.
Pad is that copper product is made.
