Abstract
The utility model discloses a kind of anti-interference motor brush to control route mechanism; including wiring board (1), brush (3); power supply (5) are housed on the wiring board; inductance (8) are housed on the wiring board and between the anode of power supply and the side of brush, overcurrent protector (6) are housed on the wiring board and between the cathode of power supply and the other side of brush；It is externally connected with left patch capacitor (41) between brush and inductance, right patch capacitor (42) is externally connected between brush and overcurrent protector, the other end of the left and right patch capacitor is grounded.The present invention effectively eliminates spark caused by brush and commutator wiper for installing and using for left and right patch capacitor; and there is good anti-interference function; the use of inductance has good filter action; the use of overcurrent protector also protects brush and commutator and related component very well; to ensure that the service life of product quality and motor, it is widely used in electric motor of automobile.
Description
Technical field
The present invention relates to a kind of electric motor of automobile, are specifically related to a kind of electricity for being especially applied to electric motor of automobile and scraping hydroelectric machine
Brush control route mechanism.
Background technique
Automobile wiper is the indispensable important component of automobile, including scrapes arm assembly, scraping blade, link mechanism, scrapes water power
Machine etc., the purposes for scraping arm assembly are to receive to be transmitted through the power come from link mechanism while generating scraping arm pressure, pass through scraping blade
Wiper is carried out to vehicle glass, to sweep the foreign matter on net glass.Currently, scrape commutator brush in hydroelectric machine at work,
Brush and commutator segment wiper can generate that spark, there are interference phenomenons, to affect the work of commutator and motor.Equally, seat
There is also the above problems for the electric motor of automobile such as chair motor, skylight motor.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings, and provides a kind of anti-interference motor that can eliminate wiper spark
Brush controls route mechanism.
The present invention is to realize by following technical solution: anti-interference motor brush controls route mechanism, including route
Plate, brush, brush carrier are equipped with power supply on the wiring board, the side of anode and brush on the wiring board and in power supply
Between be equipped with inductance, on the wiring board and between the cathode of power supply and the other side of brush be equipped with overcurrent protection；Institute
It states and is externally connected with left patch capacitor between brush and inductance, right patch electricity is externally connected between the brush and overcurrent protector
Hold, the left patch capacitor, right patch capacitor the other end be grounded.
The left patch capacitor is made of capacitor C1, C2 in parallel, and the right patch capacitor is by capacitor C3, C4 structure in parallel
At.
After structure of the invention, installing and using for left and right patch capacitor effectively eliminates brush and commutator wiper institute
The spark of generation, and there is good anti-interference function, inductance is installed and used with good filter action, overcurrent protector
Install and use and also protect brush and commutator and related component very well, to ensure that the use of product quality and motor
Service life.
Detailed description of the invention
The present invention is described in further detail with embodiment with reference to the accompanying drawing.
Fig. 1 is assembling structure schematic diagram of the invention.
Fig. 2 is circuit theory schematic diagram of the invention.
Specific embodiment
Referring to Fig.1, Fig. 2 is it is found that the present invention is applied to the anti-interference motor brush control for scraping hydroelectric machine of automobile wiper
Route mechanism processed, including wiring board 1, brush 3 (each one of left and right side), brush carrier 2 (each one of left and right side), in the wiring board
Power supply 5 is housed, on the wiring board 1 and between the anode of power supply and the side (i.e. on the left of the brush in left side) of brush on 1
Equipped with inductance 8, on the wiring board 1 and between the cathode of power supply and the other side (i.e. on the right side of the brush on right side) of brush
Equipped with overcurrent protector 6 (i.e. thermal protector FUO is one)；It is outer between the brush (brush in left side) and inductance 8 to connect
There is left patch capacitor 41, is externally connected with right patch capacitor 42, institute between the brush (brush on right side) and overcurrent protector 6
State left patch capacitor 41, the other end of right patch capacitor 42 is grounded.The left patch capacitor 41 is by capacitor C1, C2 structure in parallel
At the right patch capacitor 42 is made of capacitor C3, C4 in parallel.
Wherein, the brush 3 is by brush litzendraht wire 7 on wiring board 1.The brush 3 should move spirit in brush carrier 2
It lives, without catching phenomenon.As shown in Fig. 2, the left patch capacitor (C1, C2 are in parallel) be connected to inductance (L) and left side brush it
Between outer, the other end ground connection of the left patch capacitor；Right patch capacitor (C3, C4 are in parallel) be connected to overcurrent protector (FUO) with
It is outer between the brush on right side, the other end ground connection of the right patch capacitor；It is equipped with and changes between the brush in left side and the brush on right side
It is in contact to device (M) and by the brush on left side, right side with the commutator segment on commutator.The present invention can be widely used in seat electricity
The electric motor of automobile such as machine, skylight motor, glass lifting motor.
