Abstract
The utility model relate to a flat-type vibration motor, particularly to a flat-type vibration motor which is mounted in communication tools such as a mobile phone and the like, and used for providing vibration information for users. The flat-type vibration motor comprises a lower casing and a cover-shaped upper casing partially covering the lower casing; a magnet steel is adhered to the upper surface of the lower casing; an electric brush substrate is laid on the upper surface of the lower casing and extends from the inside the upper casing to the outside of the upper casing; one end of an electric brush arranged in the upper casing is connected with the electric brush substrate; the other end of the electric brush is warped upwards; a rotator including a reversing substrate plate, a coil and a heavy hammer is integrated with a rotating shaft through injection molding; the upper end of the rotating shaft adopts a porous bearing to support the upper casing in spinning support manner; and the other end of the electric brush is in sliding contact with the lower surface of the reversing substrate plate. In the utility model, the rotating shaft is firmly connected with the rotor, so that the quality reliability is higher; and the flat-type vibration motor solves the problems of the prior flat-type vibration motor, such as frequent looseness between the rotating shaft and the rotor, poor quality reliability, etc.
Description
Technical field
The utility model relates to a kind of flat oscillating motor, and particularly a kind of being installed on is used for providing to the user flat oscillating motor of vibration information in the communication tools such as mobile phone.
Technical background
(patent No.: CN01109584.9), it comprises a kind of flat oscillating motor: lower casing; Upper casing; Connect and support the axle of upper and lower casing; The magnet of being close to the lower casing upper side; Supported by above-mentioned eccentric shaft, the bottom surface is provided with the upper substrate of rectifier; Be arranged at several spiral coils of upper substrate one side and the resin insulator of fixing these spiral coils; Cover lower casing from top to bottom, an end connects the brush that is connected with rectifier, and what the other end exposed from the casing lower end arranges the infrabasal plate of welded disc with same distance.Relatively rotate between the rotating shaft of above-mentioned flat oscillating motor and the rotor, and interfix between rotating shaft and the upper and lower casing, this kind flat oscillating motor is because that the eccentric rotary of rotor causes easily that rotating shaft connects between rotor is loosening, thereby influence the normal operation of motor, its reliability is relatively poor.
Summary of the invention
The utility model purpose is to provide a kind of rotating shaft and rotor to be connected firmly, the flat oscillating motor that reliability is higher, solved between rotating shaft that existing flat oscillating motor exists and the rotor easily loosening, problem such as reliability is relatively poor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the lid shape upper casing that lower casing and lower casing partly cover, the upper surface of lower casing is bonded with magnet steel, the brush substrate is overlying on the upper surface of lower casing and extends to outside the upper casing in upper casing, brush one end that is positioned at upper casing is connected with the brush substrate, the other end of brush is upturned, comprise the commutation substrate, the rotor and the rotating shaft of coil and weight are injected into one, pass through the oiliness bearing swivel bearing between the upper end of rotating shaft and the upper casing, the lower surface sliding contact of the other end of described brush and commutation substrate.The utility model is injected into one with rotor and rotating shaft, and with swivel bearing between rotating shaft and the upper casing, thereby has guaranteed the fastness that is connected between rotating shaft and the rotor, has improved the utility model quality of stability.
As preferably, described upper casing becomes cylinder hole corresponding to the downward spill in the position of oiliness bearing, described oiliness bearing close-fitting in cylinder hole, thereby guaranteed the reliability that is connected between oiliness bearing and the lower casing.
As preferably, have the gap between described rotating shaft lower end and the lower casing upper surface, thereby only need carry out the assembling between rotating shaft and the upper casing, simplified assembly structure of the present utility model.
As preferably, be formed centrally in the described commutation upper surface of base plate and oiliness bearing lower end corresponding groove, described bottom portion of groove be provided with oiliness bearing under the pad of end in contact, thereby preventing to commutate between substrate and the oiliness bearing upper end friction takes place and weares and teares.
As preferably, the groove that the position of described rotating shaft and commutation substrate injection is formed with, thus guaranteed the reliability of rotating shaft and the injection moulding between the substrate that commutates.
As preferably, described lower casing circumference is formed with the arc lug, and the inwall lower end of described upper casing is formed with ring-shaped step, and the arc lug of described ring-shaped step and lower casing matches.
Therefore, the utlity model has rotating shaft and rotor is connected firmly, reliability is than characteristics such as height.
