Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model embodiment.
In figure: 1, upper casing; 2, lower casing; 3, steel axle; 4, slide plate; 5, bearing; 6, coil; 7, plastic wrapper; 8, oscillator; 9, brush; 10, commutator; 11, magnet steel ring; 12, edge is supported; 13, slot; 14, lug boss; 15, hard substrate; 16, soft substrate plate.
Embodiment
With reference to Fig. 1, the utility model embodiment comprises the upper casing 1 and lower casing 2 that mutually fasten, the center of described lower casing 2 is provided with slot 13, steel axle 3 is plugged with in slot 13, the top of steel axle 3 is fixed on the bottom surface of upper casing 1 by slide plate 4, the outside of steel axle 3 is socketed with bearing 5, the outside of bearing 5 is fixed with coil 6 and plastic wrapper 7, the outside of coil 6 is fixed with oscillator 8, lower casing 2 is fixed with brush 9, the top of brush 9 contacts with commutator 10 sliding friction, lower casing 2 is fixed with magnet steel ring 11, magnet steel ring 11 and steel axle 3 are coaxially arranged, the outer side edges of lower casing 2 supports along 12 along being provided with, upper casing 1 is fixed on and supports along on 12, the end face of upper casing 1 is 2mm to the distance of the bottom surface of lower casing 2, the external diameter of upper casing 1 is 7mm.By improving the structure of lower casing 2, under the prerequisite keeping vibrating effect, reduce the outer dia of whole motor.
The top of slide plate 4 is provided with lug boss 14, lug boss 14 and steel axle 3 interference fit, coordinated by the socket of lug boss 14 with steel axle 4, can improve the stability of steel axle in rotary course, reduce the play of steel axle, thus the concentration degree of vibration frequency when improving oscillator vibration.
The outer setting concordant with the outer of magnet steel ring 11 of oscillator 8, can reduce the external diameter of motor further.Because steel axle and slide plate 4 are fixed, so can ensure the steady of oscillator by lug boss 14.
The below of coil 6 is provided with hard substrate 15, and hard substrate 15 can reduce the resonance of brush, improves the stability that brush contacts with commutator, thus improves the stationarity of motor running, extends the useful life of brush.
The below of magnet steel ring 11 is provided with soft substrate plate 16, and brush 9 is fixed on soft substrate plate 16.Soft substrate plate 16 can reduce extraneous vibration and be delivered to intensity in motor, thus reduces brush by extraneous vibration effect, improves the smoothness that brush runs further.Meanwhile, soft substrate plate 16 can also reduce interfering with each other of the inside and outside vibration of motor.
Diameter of motor of the present utility model only has φ 7mm, greatly reduces installing space, and vibratory output can reach standard-required, and oscillator without the need to pasting, but is directly injected on pcb board, provides cost savings, improves efficiency.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
