Description

A kind of flat vibration motor brush

Technical field

Utility model belongs to brush field, in particular to a kind of flat vibration motor brush.

Background technique

Straight flow vibrating motor is mainly used in mobile phone, wrist-watch, on flat lamp electronic product, and brush is Flat DC vibration Common components on motor.

The brush of system includes a brush head and an elastic slice, and elastic slice one end and brush head are affixed, and the elastic slice other end is welded on electricity On brush substrate, brush head is resisted against on commutation substrate, and when motor operation, brush head rubs on commutation substrate, when install brush, is welded It connects and is easy to cause irreversible deformation to elastic slice, therefore generally require to go to break brush head manually to adjust brush by the later period, so that It is certain value that brush head, which projects to the distance on brush substrate, so that have between brush head and commutation substrate one it is more appropriate Pressure value breaks brush head scale manually and is difficult to hold, and worker can change head shapes if experience is insufficient, before breaking and after breaking The position that brush head is contacted with commutation substrate can change, thus the problem of causing current waveform length, the prior art, which has, to be adjusted Save the big disadvantage of difficulty.

Utility model content

The purpose of utility model is to provide to overcome the prior art to adjust the big disadvantage of difficulty and a kind of facilitate the flat of adjusting Flat vibrating motor brush.

Realization above-mentioned purpose, the utility model use following technical scheme:

A kind of flat vibration motor brush, including for be resisted against commutation substrate on brush head, further include the first elastic slice and Second elastic slice, first elastic slice one end and brush head are affixed, and the first elastic slice other end and second elastic slice one end are affixed, described The second elastic slice other end is located at below brush head.

The brush of system includes a brush head and an elastic slice, and elastic slice one end and brush head are affixed, and the elastic slice other end is welded on electricity On brush substrate, brush head is resisted against on commutation substrate, and when motor operation, brush head rubs on commutation substrate, when install brush, is welded It connects and is easy to cause irreversible deformation to elastic slice, therefore generally require to go to break brush head manually to adjust brush by the later period, so that It is certain value that brush head, which projects to the distance on brush substrate, so that have between brush head and commutation substrate one it is more appropriate Pressure value breaks brush head scale manually and is difficult to hold, and worker can change head shapes if experience is insufficient, before breaking and after breaking The position that brush head is contacted with commutation substrate can change, thus the problem of causing current waveform length, the prior art, which has, to be adjusted Save the big disadvantage of difficulty；When installing the utility model, after the second elastic slice is welded on brush substrate, then by breaking the with hand The welding ends of two elastic slices, to change the height of the first elastic slice and the second elastic slice fixed connecting end, so that changing brush head projects to brush The distance of substrate, keeps away manual-free and breaks brush head and cause brush head deformation, has the characteristics that easy to adjust；In addition, the prior art is when long Between after use, the flexibility decrease of brush is especially being inverted in use, brush head is above commutation substrate, the prior art rely on from Weight can not very well with commutation substrate contact, the utility model be inverted in use, due to the utility model have the first elastic slice with Second elastic slice, therefore be self-possessed and increase, when inversion, the pressure between brush head and commutation substrate is bigger compared with the prior art, and connectivity is more Add reliably, the utility model has the characteristics that be inverted service-strong.

To be preferred, brush head is equipped with several drag reduction grooves.

Head is equipped with drag reduction groove, and the contact area between brush head and commutation substrate reduces, between brush head and commutation substrate Resistance reduce, motor rotation it is more energy efficient.

To be preferred, the first elastic slice is arc-shaped structure, and the center of arc of first elastic slice is located at the first elastic slice close to the The side of two elastic slices.

Have in technology, in order to enable the elastic force between brush head and commutation substrate is smaller, elastic slice is made into two meander line structures, elastic slice Smaller close to brush head one end and the angle for the substrate that commutates, the angle is smaller, and elastic force is with regard to smaller, but angle is easy to make if too small It is come into contact in a large area at elastic slice and commutation substrate, in the utility model, the first elastic slice is that arc-shaped structure and center of arc are located at the One elastic slice can accomplish angle of first elastic slice between brush head one end and commutation substrate very close to the side of the second elastic slice It is small, meanwhile, it can prevent the first elastic slice from coming into contact in a large area with commutation substrate.

To be preferred, second elastic slice one end is connected with welding piece, and the welding piece is located at below brush head.

If welding piece, the utility model is fixed on brush substrate by welding piece, welding is effectively reduced and causes second Elastic slice deformation.

The beneficial effect of utility model is: (1) by with hand break the welding ends of second elastic slice, thus change the first elastic slice with The height of second elastic slice fixed connecting end keeps away manual-free and breaks brush head and cause brush head to change the distance that brush head projects to brush substrate Deformation has the characteristics that easy to adjust；(2) self weight increases, and when inversion, the pressure between brush head and commutation substrate is compared with the prior art Bigger, connectivity is relatively reliable；(3) brush head is equipped with drag reduction groove, and the contact area between brush head and commutation substrate reduces, brush Resistance between head and commutation substrate reduces, and motor rotation is more energy efficient；(4) first elastic slices are arc-shaped structure and center of arc position In the first elastic slice close to the side of the second elastic slice, it can accomplish angle of first elastic slice between brush head one end and commutation substrate Very little, meanwhile, it can prevent the first elastic slice from coming into contact in a large area with commutation substrate；(5) welding piece is added, it will be originally practical by welding piece It is novel to be fixed on brush substrate, it effectively reduces welding and causes the second elastic slice deformation.
