Description
Technical field
The utility model relates to motor parts technical field, especially a kind of brush knot for flat vibration motor
Structure.
Background technique
Flat vibration motor is mainly used in the miniature electrics such as mobile phone, beeper, electronic toy as a kind of micro motor
On product.Magneto flat vibration motor in the prior art is made of casing, rotor assembly, stator module, and wherein stator
Component is made of lower casing, magnet steel, shaft, FPCB and brush, and current has brush flat vibration motor stator structure generally to adopt
It with linear brush, is welded on FPCB, the critical component of the position in motor configuration is belonged to due to rotor portion, brush makes
It is deformed with compression can be touched in the process, but in micro motor, since overall structure is smaller, existing brush thickness is very thin,
Stress-bearing capability is poor, and in motor use process, need to apply brush certain active force, active force is usually set to low
In the critical value of brush bearing capacity to guarantee normal use, but after a period of use, with the accumulation of fatigue, brush is easy
It now deforms, so that brush end part vent sets and shifts, so that brush elastic force consistency is deteriorated, reduce brush uses the longevity
Life, while the use of motor is impacted.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of brush structure for flat vibration motor, knot
Structure is simple, is conducive to realize, effectively improves the stressed effect of brush, reduce the risk of stress deformation, improve service life.
The utility model provides a kind of brush structure for flat vibration motor, including pedestal and brush body, the brush body
One end is contact portion, and the contact portion is formed with bifurcated, and the other end is interconnecting piece, the arc-shaped setting of pedestal, the pedestal
One end is positioning region, and the other end is fixed part, and the brush body is connect by interconnecting piece with base stand location portion, the brush contact portion
It is disposed in proximity to pedestal fixed part position, is connected between the contact portion and interconnecting piece by connecting rod.
The beneficial effect being arranged in this way is: using the above scheme, this structure, when being fit into micro motor, due to
Micro motor is small in size, can be adapted to motor curved outline using the pedestal of arc, to increase the contact area of pedestal, increases
The stability for adding structure to install, while this structure, the locating height of brush bifurcated is identical with the locating height of existing brush after installation,
But existing brush structure is compared, contact portion and interconnecting piece present position respectively correspond pedestal fixed part and positioning region, elongate
Spacing between two parts, be arranged in this way it is that meet national standards simultaneously, effectively increase the length of connecting rod, increase the arm of force
Length is realized the case where not changing material so that the brush of this structure can be met deformation requirement by smaller active force
Under, increase Service Life of Carbon Brush, reduces the risk of stress deformation, effectively increase service life.
The utility model is further arranged to the pedestal fixed part and is also extended with mounting portion, the peace to interconnecting piece direction
Dress portion is provided with welding hole close to one end of pedestal interconnecting piece.
The beneficial effect being arranged in this way is: using the above scheme, in the position by welding hole setting, separate bifurcation site,
It avoids the high temperature generated when spot welding from influencing bifurcated, guarantees the using effect of brush entirety.
The utility model is further arranged to the fixed part medium position bending setting and is formed with arc-shaped notch.
The beneficial effect being arranged in this way is: using the above scheme, setting arc-shaped notch is convenient for cooperating with motor to be installed,
Structure is more reasonable, while further increasing the stability of brush installation.
Detailed description of the invention
Fig. 1 is the top view of the structure of the utility model embodiment；
Fig. 2 is the lateral plan of the utility model embodiment.
Specific embodiment
It can be seen that the utility model discloses a kind of brush structure for flat vibration motor, including base by Fig. 1 to Fig. 2
Seat 1 and brush body, described brush body one end are contact portion 22, and the contact portion 22 is formed with bifurcated, and the other end is interconnecting piece 21, described
The arc-shaped setting of pedestal 1, described 1 one end of pedestal are positioning region 12, and the other end is fixed part 11, and the brush body passes through interconnecting piece 21
It is connect with 1 positioning region 12 of pedestal, the brush contact portion 22 is disposed in proximity to 1 fixed part of pedestal, 11 position, the contact portion 22
It is connect between interconnecting piece 21 by connecting rod 23.Using the above scheme, this structure, when being fit into micro motor, due to
Micro motor is small in size, can be adapted to motor curved outline using the pedestal 1 of arc, thus increase the contact area of pedestal 1,
Increase the stability of structure installation, while this structure, the locating height of brush bifurcated and height phase locating for existing brush after installation
Together, but existing brush structure is compared, contact portion 22 and 21 present position of interconnecting piece respectively correspond 1 fixed part 11 of pedestal and positioning
Portion 12, has elongated the spacing between two parts, be arranged in this way it is that meet national standards simultaneously, effectively increase the length of connecting rod 23
Degree, increases torque arm length, so that the brush of this structure can be met deformation requirement by smaller active force, realization is not changing
In the case where becoming material, increases Service Life of Carbon Brush, reduce the risk of stress deformation, effectively increase service life.
1 fixed part 11 of said base is also extended with mounting portion 13 to 21 direction of interconnecting piece, and the mounting portion 13 is close to pedestal 1
One end of interconnecting piece 21 is provided with welding hole 14.In the position by the setting of welding hole 14, far from bifurcation site, production when avoiding spot welding
Raw high temperature influences bifurcated, guarantees the using effect of brush entirety.
The bending setting of 11 medium position of fixation portions is formed with arc-shaped notch 15.Be arranged arc-shaped notch 15 be convenient for wait pacify
The motor of dress cooperates, and structure is more reasonable, while further increasing the stability of brush installation.
The above embodiments are only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Range, therefore, equivalent variations made according to the patent scope of the utility model, such as using similar technique, similar structures
Equivalent product is still fallen within the scope of the utility model.
