The miniature motor is capable of effectively reducing the overall thickness of a manufactured electric appliance.

Description

Micro motor

Technical field

The utility model belongs to micro-vibration motor configuration design field.

Background technology

Tradition micro-vibration motor comprises motor body, metal support frame and pair of terminals; Described motor body comprises an off-centred dipole that is contained on the motor drive shaft; Described motor body is fixed in the bearing support; The mounting means of this kind micro-vibration motor is: the electric face that connects of the diapire of metal support frame and described pair of terminals is fixed on the printed circuit board (PCB) by the paster welding manner, thereby motor body also is fixed on the circuit board.

At present, the development trend of mobile phone and other vibration electrical equipment is more and more thinner, more and more littler.In order to reduce the electrical equipment volume, the available circuit plate generally all is double-sided PCBs, especially the circuit board in the mobile phone, tow sides all are laid with electronic component, the sort circuit plate is when assembling, electrical equipment will be reserved shallow storage space for the electronic component on the two sides, thereby compares with the single face circuit board, has increased thickness; But traditionally for the micro-vibration motor, all be to adopt the paster welding manner to be fixed on the one side of circuit board, because the micro-vibration motor is often all high than all the other electronic devices and components, so cause the height that thickness depends on micro-vibration motor self that takies of circuit board.But vibrating motor has the off-centred dipole of rotation, for the vibration force that guarantees to subscribe, in fact can not shorten the distance from center of rotation to the off-centred dipole outermost point.It also is limited constituting the tungsten of off-centred dipole and the proportion of other heavy metal.And in order to obtain bigger vibration force, often increase the weight of off-centred dipole.So be difficult to start with from the structure of vibrating motor self, remove to reduce thickness.

Summary of the invention

The purpose of this utility model provides a kind of micro motor that can effectively reduce made electrical equipment integral thickness.

The technical scheme that realizes the utility model purpose is: a kind of micro motor comprises motor body and the geometrical clamp that is arranged on the motor body; Described motor body comprises housing, rotating shaft, oscillator and end-cap assembly; Described housing comprises two sidewalls; Described geometrical clamp comprises the socket body that is set on the housing and protrudes from the part plate body of socket body both sides and form two welded plates that each welded plate is positioned at the middle part of the housing sidewall that is adjacent.

In the such scheme, the basic configuration of described housing is circular; The socket body of described geometrical clamp comprises straight tabular top board, protrudes the biside plate that extends to form and the connecting plate that is used for being connected the two side from the roof two side ends vertically downward; Each welded plate is to form from the outside die-cut bending of the part plate body of each side plate, and forms open-work at each side plate.

In the such scheme, described each side plate extends to the middle part that is adjacent sidewall, and the basic configuration of described connecting plate is arc shaped.

In the such scheme, described geometrical clamp is the integral piece that adopts same sheet material to make.

In the such scheme, described end-cap assembly comprises with insulation tail-hood body, is fixed on insulation tail-hood body away from two binding posts of housing one side; The diapire of described insulation tail-hood body is provided with straight locating surface; Described each binding post comprises and is fixed on insulation tail-hood body away from the fixed part on the side outer wall of housing with perpendicular to the power part of fixed part, the upper surface of described power part is connected on the locating surface, and the lower surface of described power part and the lower surface of welded plate are positioned at same plane.

In the utility model, described geometrical clamp comprises the socket body that is set on the housing and protrudes from the part plate body of socket body both sides and form two welded plates that each welded plate is positioned at the middle part of the housing sidewall that is adjacent.In actual use, can be at the default breach of circuit board, two welded plates of this geometrical clamp are weldingly fixed on the circuit board at place, described breach both sides of the edge, because each welded plate is positioned at the middle part of housing sidewall, so that the both sides of the top of motor and bottom separation circuit board, effectively reduce the integral thickness of double-sided circuit board component finished product, thereby under the prerequisite that does not change the vibrating motor body construction, effectively reduce made electrical equipment integral thickness.

Embodiment

(embodiment 1)

Fig. 1 to Fig. 2 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is a kind of perspective view of the present utility model; A kind of perspective view of Fig. 2 when to be micro motor shown in Figure 1 from another angle observe.

Present embodiment is a kind of micro-vibration motor, sees Fig. 1 to shown in Figure 2, comprises motor body 1 and the geometrical clamp 2 that is arranged on the motor body; Described motor body comprises housing 3, rotating shaft 4, oscillator 5 and end-cap assembly 6; Described housing comprises two sidewalls 31; Described geometrical clamp comprises the socket body 20 that is set on the housing and protrudes from the part plate body of socket body both sides and form two welded plates 21 that each welded plate is positioned at the middle part of the housing sidewall that is adjacent.The basic configuration of described housing is circular; The socket body of described geometrical clamp comprises straight tabular top board 22, protrudes the biside plate 23 that extends to form and the connecting plate 24 that is used for being connected the two side from the roof two side ends vertically downward; Each welded plate is to form from the outside die-cut bending of the part plate body of each side plate, and forms open-work 25 at each side plate.

In the present embodiment, described each side plate extends to the middle part that is adjacent sidewall, and the basic configuration of described connecting plate is arc shaped, also is the bottom that each welded plate is positioned at a corresponding side plate.

Geometrical clamp in the present embodiment is the integral piece that adopts same sheet material to make.
